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

The following instructions volition inform you lot on how to perform the proper set up-upward of your AutoCAD settings. This set-upward is crucial in lodge for you to produce a drawing that makes sense and is visually attractive. Read each stride carefully before performing the action required.

Things You Should Know

• At that place are two different drawing environments in AutoCAD—Model Space, in which you lot'll create 3D drawings, and Newspaper Space, in which y'all'll prepare your drawings for printing.
• When setting up your new project, you can choose appropriate measurement units, such equally decimal, architectural, or fractional.
• If a drawing is not to scale, you tin use uncomplicated math tools built into AutoCAD to scale information technology based on the measurement of one of its sides.

1. 1

   Open the AutoCAD program. The program is either shown as an icon on your desktop, or you lot may observe information technology in the Beginning menu on the lesser left corner of your calculator screen.

2. 2

   Go to modelspace. In that location are two views in AutoCAD: modelspace and paperspace. Your drawing should always exist fabricated in modelspace, and dimensions that are added later should be represented in paperspace. To switch betwixt modelspace and paperspace, view the tabs located at the bottom of the screen. 1 tab is labeled 'modelspace' and the other tabs are labeled either as 'sheet' or 'layout'. The 'sheet' or 'layout' tabs betoken paperspace.If you lot are in modelspace, the background of the screen should announced blackness. If yous are in paperspace, the groundwork should appear white.

   Gear up your units. Engineers represent units in various ways: feet, meters, etc. To ensure accuracy and eliminate confusion, it is important that the cartoon is set in the proper units. To gear up your units, type 'UN' into your keyboard and and then select the 'ENTER' fundamental. A dialog box should pop-up on the screen allowing yous to specify the unit 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 y'all are doing a project for your instructor, she should have information regarding unit specifications.

4. 4

   Select the toolbars that yous will use throughout your drawing. To do this, hover your mouse over an empty space at the top of your screen virtually the toolbars. Then right-click and select AutoCAD. A long list should bear witness up, displaying diverse toolbars containing dissimilar commands. The near pop toolbars that are used for AutoCAD 2D drawings are the Describe, MODIFY, and OBJECT Backdrop toolbars. Select these toolbars and they should pop-up on your screen. Movement them to the side to create space for your drawing. Describe TOOLBAR: contains common cartoon tools. MODIFY TOOLBAR: contains editing options. OBJECT Properties TOOLBAR: contains style and color options

5. 5

   Turn on OSNAP. OSNAP, which refers to object snap, is an extremely useful property when creating a drawing. Information technology allows you lot 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-upwardly on the screen. Click the 'SELECT ALL' push, ensuring that all OSNAP properties are turned on.

1. 1

   Import or go to the Autocad drawing that is not to scale. It is okay if the Autocad drawing is not to calibration, equally long as yous know at to the lowest degree 1 length. Type in "Un" followed by the space bar to change the units. Make certain the units are architectural and the precision is i/half dozen".

2. 2

   Identify one line segment in the cartoon that you know the length of. This can be a wall length or the length of a building. Larger lengths make more authentic scaling in Autocad. You practise not desire to scale the whole drawing past the width of a door or the length of a slice of article of furniture, for example.

3. iii

   Measure the length of the line segment that you lot chose in Step 2. Click on the line, type "properties" followed by the space bar in the command prompt. Gyre downwards the pop upwards window until you meet the length of the line. Write this number down. Yous can also depict a new line in the drawing to scale from, if the line doesn't exist in the drawing, like the length of a building, for case.

4. 4

   Split up the length the line should be past the length the line is in the drawing. (length total scale) / (length measured in drawing). You should get a decimal number. Write this number down.

5. 5

   Type "scale" into the command prompt followed by the space bar. So select the unabridged AutoCad cartoon and press the space bar. So click whatsoever part of the drawing. You will come across equally y'all move your mouse, AutoCad is attempting to manually scale the drawing. Do not click a second fourth dimension. Instead blazon in the command prompt the decimal number y'all got from Step 5. Then press the space bar. The cartoon should exist scaled accurately.

6. vi

   Check the line that you measured in step two to make sure the calibration is at present accurate. If it is close, but slightly off, you may take non included enough decimal places in your scale calculation. Only repeat steps iii-half-dozen for the new scaled drawing to get the scale fifty-fifty more than precise. Later on a second run of the calibration, the AutoCad drawing should be accurately scaled.

1. 1

   Check the settings. Earlier scaling, you lot should make certain that all layers are set to ON and UNLOCKED.

   • Note: Pretty much the aforementioned procedure tin be used when rotating an object by an undefined angle.

2. 2

   Apply the following:

   • Command: Line --> Draw a line of a length that you want to use (for example, you have an object in your drawing, and you lot desire information technology to be 100 units long, then draw a 100 units long line). This is going to be your reference length.
   • Command: Scale --> select entire cartoon, except your reference line, printing space.

3. 3

   Select the base point.

   • Blazon "re" (as reference), press space.
   • Option showtime bespeak and endpoint of the object from your drawing, that you want information technology to be 100 units long.
   • Type "po" (equally points), press space.

4. 4

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

5. 5

   Done. Instead of you having to calculate and writing down decimals, now AutoCAD will practise it instead, and the result will be most accurately scaled drawing.

• Question

  How do I remove the grid background then that I have a blank canvas?

  

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

• Question

  How exercise I increase dimensions in AutoCAD?

  

  There are two simple ways to change the overall size of your drawing: stretch or calibration. If y'all're drawing a 2x2 foursquare, for example, you tin stretch it to make it 2x3, 2x4, etc. It moves the endpoints of your windowed selection. Scaling the drawing would involve selecting a base indicate as well as onetime and new reference points. You lot could then scale the 2x2 drawing to 3x3, 4x4, etc.

• The following lists unremarkably used commands that are helpful in creating an AutoCAD cartoon:

  • Abolish - cancels a control. 'ESC'
  • Undo - undoes your terminal command. 'CTRL' + 'Z'
  • Erase - erases an object, line, or other item. E' + 'ENTER' fundamental
  • Circumvolve - creates a circle with a specific radius. 'C' + 'ENTER' key --> input radius length + 'ENTER' fundamental
  • Line - creates a line of a certain length. 'L' + 'ENTER' fundamental --> input length of line + 'ENTER' fundamental
  • Rectangle - creates a rectangle of certain dimensions. 'REC' + 'ENTER' key --> input dimensions +'ENTER' key
  • Trim - trims a line to an earlier betoken of intersection. 'TR' + 'ENTER' key --> select line beingness trimmed +'ENTER' key --> select side of line to exist trimmed
    • Note: line must be intersected by another line in order for it to be trimmed.
