Convert decimal geographic coordinates to degrees, to UTM and draw in AutoCAD
How to change the unit of measure in AutoCAD. How to calculate the area in an auto cad. How to find the area in AutoCAD in a standard way This program is either present as an icon on your desktop, or you can find it in the Start menu in the lower left corner of the screen. Go to Model Space. Your drawing should be made in Model Space, and dimensions added later should be presented in Sheet Space. To switch between model and sheet spaces, look at the tabs at the bottom of the screen.
If in model space mode now, the screen background should be black. If you are in Sheet Space mode, the background should be white. Set the units. Engineers set different units of measurement: feet, meters, etc. In order to ensure accuracy and avoid confusion, it is important that the drawing is made in appropriate units. A dialog box should appear that allows you to specify the units and accuracy.
Type options for units of measure are as follows: Decimal, Scientific, Engineering, Architectural, Fractional. If you are doing a project for your teacher, he should have information regarding the specification of units.
Select the toolbars that will be used to create your drawing. To do this, hover over the blank space at the top of the screen next to the toolbars. Right-click and select "AutoCAD. Select these panels and they should appear on the screen.
Move them aside to create space for your drawing. The Drawing panel contains basic drawing tools. The Editor panel contains editing tools. The Object Properties panel contains style and color controls Turn on the "Snap" mode. It allows you to see where the middle and end point of the line is located, the tangent of a circle, and other useful information. To enable the Snap mode, press the F3 key on the keyboard. A dialog box should appear on the screen.
When you move the mouse cursor, the coordinates of its position are displayed simultaneously. They coordinates are shown with a status line. To mark the coordinates of points on the monitor, you can either enter them manually from the keyboard, or simply mark them using ordinary mouse clicks on the desired point. But before doing this, we need to understand what these coordinates are, how they scale and how they are displayed.
In AutoCAD, arbitrary units are entered as units. They are not tied to either metric or any other units of measure. And the number, say, 20, is only the number 20, and it depends entirely on you what meaning you put into this number - 20 millimeters, 20 feet or 20 meters. In addition, AutoCAD allows you to perform some calculations: calculate the area, length of plots, etc.
The result will also be displayed in arbitrary units. As a result of the above, you as a developer must accept for yourself some measurement system meters so meters, feet so feet and adhere to it throughout the entire development phase of the drawing. From the foregoing, the question naturally arises of the scale that will be used in our drawing.
Based on our extensive experience in developing projects in AutoCAD, we recommend choosing a drawing scale of 1: 1. Everything follows from the same convenience and possibility of calculating implicit and not specified, but required by us parameters, and when printing the drawing can be scaled to any paper size convenient for us. But in order for all the settings by coordinates to be displayed in a form that is readable to us, you need to enter some settings in AutoCAD using the Units command.
As a result, a dialog box appears on the screen with the ability to set parameters for units of measure. Consider this dialog in more detail. TYPE - type of units to select.
In this setting, we need to enter the number of significant decimal places for us. For example, on the monitor you see the coordinate To increase accuracy when drawing, you need to use, for example, coordinate input, but we'll talk about this later. This parameter specifies the accuracy for angular quantities such as radians, degrees, minutes, seconds. The direction of the positive angle reference is set here in the default settings, this direction is the counterclockwise direction , but if this direction does not suit you, you can change it in this parameter.
Drag and Drop Scale - in this parameter, units are set for their binding to fragments of other drawings when they are transferred to our created project, but this ratio will be used only if there are certain commands, so use this option with caution.
With its help, we have the opportunity to set the direction from which the angles will be counted. The default direction is East - East direction of the X axis. But if necessary, this direction can be changed by default. So, to summarize all of the above. In this lesson, we learned how to customize the unit system for our drawings. Follow these steps to set up linear units.
Select a command from the menu Format »Units or enter the command in the command window Units or simply units. In the dialog box that opens Drawing units fig. Value selection Scientific leads to the fact that all sizes will be indicated in the so-called scientific format for example, the value 2. In order to understand how the different types of unit systems differ, try to choose some other value from the list Format and pay attention to the examples presented in the field Example. To return to the metric units, select Decimal.
Now pay attention to the two drop-down lists. Accuracywhich in groups Linear and Corner are under the lists Format. Click on the expand button Accuracy in Group Linear. Decimal Fig. Drop-down lists are controls in which the current item is displayed in a minimized state. After clicking on the button for expanding the list it shows a triangle pointing down , the entire list is displayed on the screen, which allows you to select another element from it. After selection, the list is closed and only the selected item is displayed in it.
As with switches, only one item can be selected from the drop-down list. The accuracy set using this list only affects the accuracy of the linear dimensions in the AutoCAD drawing. If the accuracy is 0. However, the line will actually have a given length of 2. If you change the accuracy value to 0. Select from the list Accuracy paragraph 0.
After you have configured the program and saved, if there is such a need, the settings in the file, you must go to the drawing settings. All settings and manipulations performed on the drawing will be saved along with it.
Moreover, all settings will be available for editing at each drawing opening session and will relate to this particular drawing. The main settings of the drawing are: limits, line types, dimensional and text styles.
Basically, the tincture of the drawing in programs like AutoCAD are performed interactively or in the form of a user dialogue with the program. All this activity is carried out with the help of teams.
In turn, commands are entered using the menu, on the toolbar, or by entering the name of the command on the command line. We will not consider entering commands using the menu and toolbar. To enter commands directly into the command line requires knowledge of their names. About limits.
AutoCAD has two spaces — these are model and sheet spaces. Basically, a drawing is created in the model space, in which the workspace is infinite. Limits are set by the coordinates of the lower left and upper right corner of the rectangular area. AutoCAD will display a comment line below the command.
What does it mean? This, for example, means that when you set the coordinates of the upper right corner when setting limits to ,, then only you will know what these numbers mean specifically.
That is, they are given in millimeters, kilometers, or other units. Let's adjust the value of the units. See pic. To do this, in the list Accuracy set the value to. By default, positive angles are counted counterclockwise from the direction of the axis X.
If necessary, specify a different direction of the reference angles in the dialog box Drawing units need to press a button Direction and in the called dialog Direction selectionnote the required reference direction. Now you need to check these settings, to do this, move the mouse in the drawing area and see how the coordinates change. Yeltsin Design in AutoCad
How to make dimensions in AutoCAD. Computer help. Dimension Styles in AutoCAD
This is due to misunderstanding the AutoCAD drawing space and how it works. Drawing Units Generally you will draw in either: Metric mm, m, km etc. Imperial inches, ft etc. These could be anything, i. During drawing setup, you choose settings for length units for measuring linear objects and distances and angle units for measuring angles between nonparallel objects or points on arcs or circles in the Drawing Units dialog box. The base unit is the inch unless otherwise specified, so if you enter a number like An example would be Scientific units, also unitless and show values as exponents, are used for drawing really tiny or really large things.
If you design molecules or galaxies, this is the unit type for you. Examples would be There is no degree symbol on a standard keyboard, so AutoCAD uses the lowercase letter d. One nautical mile 6, feet is approximately 1 minute of arc of longitude on the equator. David Letterman once said that the equator is so long that it would reach once around the world. Grads and Radians are mathematically beautiful but are not widely used in drafting.
The only setting that you might need to specify is the one that controls the display style of the units that you plan to use. For example, the Architectural units style displays symbols for feet and inches, while the Decimal units style does not. So where do I change these? You can change them in the drawing units dialogue box in AutoCAD. Of course that means you can draw you entire floorplan in the units you want to draw, and if you realize you would like to change them later on, simply use the above menu.
No modification needed. But what if, for example, you want to add in a block that is drawn in inches to a drawing that is done in mm? Well, here you would have to use a little math to scale the relationships in. You can also do this to the entire drawing: Click Home tab.
Enter data with bearings and distances in Microstation
Delete the "save last angle" This is a fairly common error, and if it is not configured when creating a line, the system considers the last line as a base angle, as if we were to work by deflections and it is necessary to be right-clicking each line segment. To avoid the problem, when activating the line command, you have to remove the option "Rotate AccuDraw to segments" as it appears in the following graph.
Activating the AccuDraw Once you start inserting lines, when you place the first point the "Place smart lines" panel appears, to activate the "AccuDraw" panel press the "Toggle AccuDraw" button, if no being available is activated by right-clicking on that zone and selecting an option to display it.
As you can see, there appears the panel to enter the distance and angle in "Bearing" format. Once entered the data must be entered, and so on until the polygon is completed. Switch between Rectangular and Polar To change between this option and the one of XY coordinates, the shortcut letters are used: It means that when the AccuDraw is activated, the blue zone is clicked and any of the "X" or "Y" keys are pressed, the panel changes immediately to be able to enter coordinates.
To move to distance form, angle any of the "A" or "D" keys is pressed. Dropdown Fraction format Fraction Format You can select the display option for fractions. This setting is available only when the list Unit format Unit format item selected Architectural Architectural or Fractional Fractional.
If the list Unit format Unit format value selected Decimal Decimal then dropdown Decimal separator Decimal separator You can set the character used as the decimal separator.
In field Round off Rounding sets the rounding rule for dimensions of all types except corner. If you enter 0. If you enter 1. The number of digits displayed after the decimal point depends on the parameter value Precision Accuracy. In field Prefix Prefix You can set a prefix for the text value of the dimension. The specified text will be placed before the default value. You can enter any text in this field or use control codes to display special characters. In field Suffix Suffix you can also specify additional text, but in this case it will be placed after the default value.
For example, you can enter the inch character " and the program will insert it after each dimension value. Region Measurement scale Measurement Scale contains options to define the scale factor for the default dimension values.
Parameter Scale factor Scale factor defines the scale factor for linear measurements. The value of any linear dimension is multiplied by this factor, and the final value is used as the default text. For example, if you set a dimension scale factor to 2, then the text dimension value for a 1 "line will be displayed as 2". The value does not apply to angular measurements, rounding, or positive or negative tolerances.
If the checkbox is checked Apply to layout dimensions only Apply only to layout dimensionsthe scaled size value will only apply to dimensions created in layouts view sheet space. Settings in the area Zero suppression Suppress Zeros controls the display of leading and trailing zeros in text dimension values. For example, if you are using decimal units, check the box Leading Leading means that the value 0. When checked Trailing The final size Using fields Sub-units factor Subsize factor and Sub-units suffix Sub-size suffix You can specify the sub-size factor and suffix.
For example, if the unit is 1 m, you can specify a sub-size factor of and a sub-size suffix cm. In this case, when the size value is less than 1, for example 0. Checkboxes 0 feet 0 in feet and 0 inches 0 in inches controls the display of zeros in dimensions expressed in feet and inches. For example, if the checkbox 0 feet 0 in feet is checked, a value of 0 "8" will display as 8 ". When checked 0 inches 0 in inches a value of 12 "0" will display as 12 ".
Alternative units Tab Alternate units Alternative units allows you to display dimensions in two different formats fig. A typical example is displaying dimensions in both millimeters and inches at the same time, for example 2.
To allow the use of alternate units, select the checkbox Display alternate units Display alternative units. Alternate unit options Parameter value Unit format Unit format and Precision Accuracy does not differ from similar settings on the tab Primary Units Basic units.
When using fractional formats architectural and fractionalyou can choose between framed and uncomposed fraction types. Settings Multiplier for alt units Multiplier for alternate units and Round distances to Round distances to define the conversion factor between the primary and alternative units. For example, to convert inches to millimeters, enter a factor of This value does not affect angular dimensions.
This rounding value is independent of the primary unit rounding value. Options Prefix PrefixSuffix Suffix and checkboxes in the area Zero supression Suppression of zeros are set in the same way as for base units. For example, to place mm after the alternate units, enter Suffix Suffix the corresponding value. By switch Placement Placement you can choose where the alternate units will be displayed: after the main value After primary value or under it Below primary value.
Setting up Method Method controls the display of tolerances.
Parameter Precision Precision and checkboxes in areas Zero supression Suppression of zeros works the same way as in tabs Primary Units Basic units and Alternate units Alternative unitsbut only control the tolerance values. Tolerance parameters In the fields Upper value Upper limit and Lower value Lower limit You can set the upper and lower limits of the tolerance parameter values.
Using the field Scaling for height Scaling for Heightyou can set the relative size of the text tolerance value. This is the scale factor multiplied by the base unit text height. For example, if you specify a value of 0.
In the list Vertical position Vertical Position select the vertical position of the main text value of the dimension in relation to the tolerance text: Bottom From below Middle Middle or Top Top. Let's look at how to modify an existing sizing style. Select the dimension style you created earlier Mech and click on the button Modify Edit. A dialog box will appear Modify Dimension Style Change dimension style.
On the tab Text Text click the ellipsis button next to the list Text style Text style. A dialog box will appear Text Style Text style. Select from the list Text style Text style text style DIM, which you just created and set the parameter Text height Text height equal to 0. Press the button OK, to save the sizing style changes and return to the window Dimension Style Manager Dimension style manager. Choose size style Mech and click on the button Set Current Set Current to set this dimension style as current.
The dimensions associated with this style will be updated. Any drawing in AutoCAD contains various sizes, which are an integral part of graphic information for workers in production, construction, management and many other industries.
In this chapter, we covered the basic commands and interface elements in AutoCAD for inserting and editing linear and angular dimensions. AutoCAD provides the user with a variety of tools for creating, modifying and updating dimensional objects.
Effective use of dimension styles and the ability to properly set dimension parameters is the key to your success in AutoCAD. It is recommended to set dimensions in AutoCAD after all types and elements of the drawing are ready.
Having learned how to put them, you will understand how to change sizes in AutoCAD. The topic is very important, since the presence of dimensions distinguishes a drawing from an ordinary picture. Most sizes have tolerances and corresponding qualifications of manufacturing accuracy, a competent specialist is obliged to appoint and indicate them on the drawings.
The panel has only two buttons related to dimensions. Under the number 1 there is an opportunity to select the type of size, under the number 2 there is an automatic selection of the size, that is, the program itself determines what type of size the user wants to indicate diameter, angle, arc length, etc.
To select the size type manually, click on the triangle next to button 1 and see the possible options. Before setting the dimensions, you need to adjust the style. Without the appropriate settings, the picture will look like this. This indicates that nothing is configured. Setting up. So, in the panel, select "Annotations". Then select the dimension style line. This is the second line with the size character. Click on the inscription "Standard" and then "Control Dimension Styles".
The current style must be edited with the necessary settings. In the line settings, you must specify the color and type of lines by layer. Specify the line weight 0. We set the step in base dimensions 10, then the color of the extension lines, as well as the type of the first and second lines - by layer. We also set the line weight to 0. Moving on to symbols and arrows.
In this section, it is enough to adjust the dimensions of the arrow and the location of the arc length above the dimension text. Optionally, you can choose how the arrows will look. The filled closed arrow is a classic look.
One of the most interesting and important tabs is text. Editing the color and placement of the text. I prefer vertical alignment in the center of the line, and orientation along the line. The location and size of the text of the dimension line in the drawing is regulated, pay attention to this.
Understanding Units in AutoCAD
You need to edit the text style, or create a new one, for this, click the ellipsis next to the name of the default style. Shown in the picture with an arrow and number 1. There is a choice to customize the current style, or create a new one.
In a style, you can customize the font name, typeface, character height, stretch ratio and effect. The typeface can be regular, italic, bold, bold italic. Any height value can be chosen, but pay attention to the regulations.
The stretch ratio is usually set to 0. After entering all the values, click "Apply" and go to the placement tab. It doesn't make much sense to make changes in placement. Optionally, you can set the scale of the dimensions to the sheet and fit the elements.
If you decide to fit the elements, I recommend manual placement. The basic units allow you to determine the dimensional accuracy as well as the scale.
In the tutorial, I said that when you scale, the dimensions change. In the base units section, you can enter a scale factor that will take into account the scale of the view. The precision is responsible for the number of characters after the decimal point. It makes no sense to focus on alternative units, since they are used very rarely, and, if you wish, you can deal with them yourself.
In tolerances, we set deviations for the nominal size. Choose a size type, or automatic size. To specify the diameter, select the size type diameter, for the radius, respectively, the radius. To edit any size, just double-click on it with the left mouse button and make changes. Now you know how to set dimensions in AutoCAD and you can answer. Anything that remains incomprehensible, please state it in the comments at the bottom of the page. Answer: Theory: The size in the drawing shows the dimensions of the part or circuit: length, width, radius of a circle, hole diameter, wire twist pitch, etc.
Dimensions in AutoCAD are needed in order to indicate to the installer, locksmith, or any other person who will manufacture the product according to your drawing - what size should this or that element of the drawing be made, what tolerances to take. In addition, the dimensions on the drawing in AutoCAD or Compass are a tribute to the Soviet era, in which it was customary to designate the dimensions of parts according to certain rules.
Simply put, dimensions are nothing more than arrows with numbers. All of you have probably seen them sometime. Practice: Now we will master in practice the techniques of specifying dimensions in the drawing in AutoCAD. Since almost all parts of the drawing represent some kind of geometric figure, you first need to figure out for yourself how to set the dimensions in the AutoCAD for such simple figures as a rectangle, a circle, 2 parallel lines, an angle.
If you look at this item, you will see that there are different types of sizes: linear, parallel, angular, radius and others. All of them, in fact, represent a line with an arrow-pointer, as well as a numeric designation of the size above the arrow or inside the arrow you can change it yourself.
But the shape of the arrow will change depending on which geometric shape you set the size. Consider the main types dimensions in the drawing. I have prepared a segment in advance, the size of which I want to indicate. After the linear dimension is selected, you need to left-click the left and right ends of the segment once.
A preview of the dimension will appear, which now needs to be raised to the height you want to make the leader line with the dimension. The size indicator can be omitted, but in ESKD it is customary to designate the size above the part. We left-click on the part of the screen where you want to place the dimension line, and our size is ready! Now you can not only put dimensions in autocad for a simple line, but also indicate almost all dimensions of parts. To apply the size of the part in the AutoCAD we do exactly the same, but now we mark with the mouse the start and end points of the part, and not the lines.
There are 2 small remarks. The first concerns the case when you want to set the size of the part not completely, but say, the size half of the part. In this case, we mark the second point with the mouse not at the end of the part, but where you want to end the dimension line. If you have already drawn a dimension line and want to move it, this is easily done using the blue squares that appear when you select the size of the part with the right mouse button.
Second important note. How to resize in AutoCAD? AutoCAD supplied the size number automatically. You can change this number in the size properties. To do this, do the following: 1. Select the dimension line with the left mouse button. Right-click on the line with the size to call the menu Properties I have Properties appeared as a window in the upper right corner of the screen. Scroll down the field with properties, and find the item there Textwhich has a field Text string This is what we brian haney wedding to resize in autocad We write in it the value we need.
The dimension above the dimension line has now changed. In the same menu, you can set various size properties in AutoCAD, such as font, size, alignment, color, arrow type and much more. I will not describe in detail all the properties here.
Who needs - see the menu Properties at the size. The size of the circle in AutoCAD radius or diameter. They are essentially the same size, since the radius is half the diameter. Let's set the size for the previously prepared circle in AutoCAD. We choose: Size-Radiusmustache or Dimensions-Diameter. It turns out one of the options: The size number above the line changes in the same way as in the case of the linear size: PropertiesText - Text string.
Parallel Dimension in AutoCAD Now let's try to put a parallel dimension - the dimension between two parallel lines in the drawing.
Measure almost anything with the MEASUREGEOM command
For a change, I have drawn a rectangle, and I want to put the size between its two parallel sides. In the top autocad menu, select: Dimensions-Parallel.
With the left mouse button, select 2 lines of the rectangle in turn. We get the size between two parallel sides: In principle, the example is not very successful, since here one could get by with a linear dimension. But if you need to put in AutoCAD the size between two parallel lines that are not connected to each other in any way, then in this case the parallel size will be simply irreplaceable. We already know how to change the number 40 read above Angular dimension in AutoCAD The penultimate example for today is the designation of the angular dimension.
Let's say we have a triangle, and we need to indicate in degrees the value of one of its angles. We choose: Dimensions-Angular Then, with the left mouse button, select two adjacent sides of the triangle, between which you need to set the size of the corner. Push Enterand our angular size is ready! In the drawing, it looks like this: I talked about the most common types of dimensions in AutoCAD, and how they can be put on the drawing.
