Millions of civil engineers worldwide use AutoCAD to help create visual representations of important projects. Buildings, bridges, and cityscapes come alive in AutoCAD and allow engineers, clients, and the public to better empathize a certain design. AutoCAD is an essential visual communication tool for civil engineers.

The post-obit instructions will inform you on how to perform the proper set-up of your AutoCAD settings. This prepare-up is crucial in gild for you to produce a drawing that makes sense and is visually attractive. Read each footstep carefully before performing the action required.

Things You Should Know

There are two different drawing environments in AutoCAD—Model Infinite, in which you lot'll create 3D drawings, and Paper Space, in which you'll prepare your drawings for printing.
When setting upwardly your new project, y'all can choose appropriate measurement units, such as decimal, architectural, or fractional.
If a drawing is non to scale, you can use simple math tools built into AutoCAD to scale information technology based on the measurement of one of its sides.

one

Open the AutoCAD plan. The program is either shown as an icon on your desktop, or y'all may find it in the START menu on the bottom left corner of your computer screen.
2

Get to modelspace. In that location are two views in AutoCAD: modelspace and paperspace. Your drawing should always be made in modelspace, and dimensions that are added afterwards should be represented in paperspace. To switch between modelspace and paperspace, view the tabs located at the lesser of the screen. One tab is labeled 'modelspace' and the other tabs are labeled either as 'sail' or 'layout'. The 'canvas' or 'layout' tabs indicate paperspace.If you are in modelspace, the background of the screen should announced black. If you are in paperspace, the background should appear white.

Fix your units. Engineers represent units in various ways: feet, meters, etc. To ensure accuracy and eliminate confusion, it is of import that the cartoon is set in the proper units. To ready your units, type 'UN' into your keyboard and then select the 'ENTER' key. A dialog box should pop-up on the screen allowing you to specify the unit of measurement type and precision for your units. The options for the unit types are: DECIMAL, SCIENTIFIC, Engineering, ARCHITECTURAL, Fractional. The 'precision' section allows yous to pick the number of decimal places for your dimensions. If you lot are doing a project for your teacher, she should have information regarding unit of measurement specifications.
4

Select the toolbars that you will apply throughout your drawing. To do this, hover your mouse over an empty space at the top of your screen well-nigh the toolbars. And then correct-click and select AutoCAD. A long listing should show upwardly, displaying various toolbars containing different commands. The most popular toolbars that are used for AutoCAD 2D drawings are the Draw, Change, and OBJECT Properties toolbars. Select these toolbars and they should pop-up on your screen. Move them to the side to create space for your drawing. Describe TOOLBAR: contains common drawing tools. Alter TOOLBAR: contains editing options. OBJECT Backdrop TOOLBAR: contains style and color options

Turn on OSNAP. OSNAP, which refers to object snap, is an extremely useful belongings when creating a drawing. Information technology allows you to see where the midpoint and endpoint of a line is located, where a tangent is on a circle, and other useful information. To turn on OSNAP, printing the F3 button on your keyboard. To ensure your OSNAP settings are on, right-click on the icon reading 'OSNAP' located at the bottom left-hand corner of the screen. A dialog box should pop-upwards on the screen. Click the 'SELECT ALL' button, ensuring that all OSNAP backdrop are turned on.

Import or go to the Autocad cartoon that is not to scale. It is okay if the Autocad drawing is non to scale, equally long equally you know at least one length. Type in "Un" followed by the space bar to change the units. Brand sure the units are architectural and the precision is 1/half dozen".
two

Identify one line segment in the drawing that you know the length of. This can exist a wall length or the length of a edifice. Larger lengths make more accurate scaling in Autocad. Y'all do not desire to scale the whole cartoon by the width of a door or the length of a piece of furniture, for example.
3

Measure out the length of the line segment that yous chose in Step 2. Click on the line, type "properties" followed by the space bar in the command prompt. Ringlet downwardly the pop up window until y'all run across the length of the line. Write this number down. You can also draw a new line in the drawing to scale from, if the line doesn't exist in the drawing, like the length of a edifice, for example.
iv

Separate the length the line should be by the length the line is in the drawing. (length full calibration) / (length measured in cartoon). You lot should get a decimal number. Write this number down.
five

Type "scale" into the control prompt followed by the infinite bar. So select the entire AutoCad drawing and press the infinite bar. Then click any part of the drawing. Y'all will run into as y'all movement your mouse, AutoCad is attempting to manually scale the cartoon. Practise not click a 2d fourth dimension. Instead type in the command prompt the decimal number you got from Step 5. Then press the space bar. The drawing should be scaled accurately.
6

Cheque the line that you measured in pace two to brand certain the scale is now accurate. If it is close, but slightly off, you may have not included enough decimal places in your scale calculation. Simply repeat steps 3-6 for the new scaled drawing to get the scale even more precise. After a second run of the calibration, the AutoCad cartoon should be accurately scaled.

one
Check the settings. Before scaling, you should make sure that all layers are set to ON and UNLOCKED.
- Note: Pretty much the aforementioned process tin can exist used when rotating an object by an undefined angle.
2
Use the following:
- Command: Line --> Draw a line of a length that you want to use (for example, y'all have an object in your drawing, and y'all want it to be 100 units long, so draw a 100 units long line). This is going to exist your reference length.
- Command: Scale --> select entire drawing, except your reference line, printing space.
3
Select the base betoken.
- Blazon "re" (as reference), printing space.
- Option first point and endpoint of the object from your cartoon, that you desire it to exist 100 units long.
- Blazon "po" (equally points), press infinite.
4

Pick outset point and endpoint of your referenced line that you drew.
5

Washed. Instead of y'all having to summate and writing downward decimals, at present AutoCAD will do it instead, and the upshot will be most accurately scaled drawing.

Question

How do I remove the filigree background so that I have a bare canvas?

Select the layout filigree. Click the grid line to be removed from the grid.
Question

How do I increase dimensions in AutoCAD?

In that location are 2 unproblematic ways to alter the overall size of your cartoon: stretch or calibration. If you're drawing a 2x2 square, for example, you tin stretch information technology to get in 2x3, 2x4, etc. It moves the endpoints of your windowed selection. Scaling the drawing would involve selecting a base indicate as well as one-time and new reference points. You could then scale the 2x2 drawing to 3x3, 4x4, etc.

The following lists commonly used commands that are helpful in creating an AutoCAD drawing:
- Cancel - cancels a command. 'ESC'
- Undo - undoes your final control. 'CTRL' + 'Z'
- Erase - erases an object, line, or other item. Eastward' + 'ENTER' cardinal
- Circle - creates a circle with a specific radius. 'C' + 'ENTER' key --> input radius length + 'ENTER' key
- Line - creates a line of a certain length. 'L' + 'ENTER' key --> input length of line + 'ENTER' key
- Rectangle - creates a rectangle of sure dimensions. 'REC' + 'ENTER' key --> input dimensions +'ENTER' key
- Trim - trims a line to an before point of intersection. 'TR' + 'ENTER' central --> select line existence trimmed +'ENTER' key --> select side of line to be trimmed
  - Note: line must exist intersected by another line in order for it to be trimmed.
