how to do a 3d drawing in autocad
Topics covered in this Lesson:
Isometric Drafting Techniques
Isometic Cartoon
Using Isometric commands is i of the simplest ways to requite a 3-D representation while using simply two-D commands. This has been the usual way of doing things before CAD allowed true 3-D work to exist done. Many times an isometric drawing is used to compliment or give more information to a three view orthographic drawing. See the sample below.
You tin can see that information technology is a very simple drawing. This basic isometric cartoon of the object gives a very proficient idea of what information technology looks like. If this is all that is needed then isometric works well. Unfortunately, as before long as yous modify anything, like the block'due south summit, you'll demand to redraw all four views.
AutoCAD has a command called ISOPLANE which allows you lot to easily depict at a 30 caste angle as needed for an isometric drawing. Y'all can switch betwixt the three 'isoplanes' (top, right, left) by using this command or past pressing the F5 key.
Command: ISOPLANE <ENTER>
Current isoplane: Correct
Enter isometric plane setting [Left/Elevation/Right] <Left>: T <ENTER>
Current isoplane: Height
Newer versions of AutoCAD have an Isoplane icon on the status bar. You lot can click this to enter Isometric Drafting Mode equally shown below. You can also alter your Isoplanes here (merely F5 is faster).
By invoking this command, AutoCAD is now set to depict on the pinnacle isoplane past default. Your other choices would be Left or Right. Your outset do volition be to draw the object shown above using isometric methods.
Practice one - Isometric Drafting
Begin a new cartoon using the acad.dwt template
Create a layer called OBJECT and give it a light-green color. Brand this your current layer.
Type in DDRMODES to bring upward the Drawing Aids dialog box. Make your settings the same as what y'all see beneath (simply plough on Isometric Snap).
Notation :
Retrieve this dialog box for later. When you are washed with Isometric Drafting, open this dialog box again and change the radio push button from "Isometric snap" to "Rectangular snap" to get dorsum to the regular cartoon settings.
Printing OK and you'll see that the grid is set up for isometric drawing for the left isoplane in one/two unit increments. Your crosshairs are now angled to prove you which isoplane you are currently on and the Grid is laid out differently from what you may be used to.
Begin past drawing the left side of the box (shown at the peak of the lesson) using the line command. Ignore the hole at this point. You lot volition want to use the Direct Distance Entry Organisation for this exercise and make sure that you have Ortho ( F8) and Osnaps ( F3) turned on.
Switch to your right isoplane ( F5) and draw the correct side.
Switch to your top isoplane ( F5) and draw the top view.
Create the angle lines to add the angled surface.
Switch back to the left isoplane and start the ELLIPSE command. At the command prompt, press I for isocircle. This will allow yous to create an ellipse at the correct angle based on the radius of the circle in the orthographic drawing. Use the Osnap to pick the right middle point.
Save your drawing in your CAD folder. (You lot have a CAD Folder by at present, right?)
To dimension an isometric drawing, yous have to do a few things first. Create a text style called Left, and give it a thirty o obliquing angle, then create another called right with a -thirty o obliquing angle. So create a new dimension style that has the text aligned with the dimension line. Afterward yous accept placed a dimension, use the DIMEDIT command to change the obliquing angle of the dimension + or - thirty degrees. You may as well need to use the properties to change the text in the dimension to left or correct depending upon the orientation of the dimension.
Proceed in mind that this is nevertheless only 2d. Call up that in some instances, it may be quicker and easier to use this method rather than the more complex 3-D methods yous'll be learning in the following lessons.
Extra Practice: Re-create this drawing using isometric cartoon methods.
Extra Practice: Copy this drawing using isometric drawing methods. If you want to add together the hidden lines, jump ahead to Lesson 4-3 to larn about linetypes.

Fun fact: Autodesk, like many other software companies, was challenged past the effects of software piracy in the early 1990s. The visitor has prevailed in litigation to protect its copyrights, including a 1994 suit against Cadisys Corporation, the result of which was a $100,000 settlement in Autodesk'south favor on May 23, 1994.
