INTRODUCTION TO ISOMETRIC VIEW
AutoCAD has a command called ISOPLANEwhich allows you to easily draw at a 30degree angle as needed for an isometric drawing. You can switch between the three 'isoplanes'
(top, right, left) by using this command or by pressing the F5key.
Command: ISOPLANE
Current isoplane: Right
Enter isometric plane setting [Left/Top/Right] : T
Current isoplane: Top
By invoking this command, AutoCAD is now set to draw on the top isoplane. Your other
choices would be Left or Right. Your first exercise will be to draw the object shown above usingisometric methods.
ISOMETRIC DRAWING
Begin anewdrawing using the acad.dwt template
Create alayercalled OBJECTand give it a green color. Make this your current layer.
Type in DDRMODESto bring up the Drawing Aids dialog box. Make your settings the same as
what you see below (just turn on Isometric Snap).

Press OKand you'll see that the grid is set up for isometric drawing for the left isoplane
in 1/2" increments. Your crosshairs are now angled to show you which isoplane you arecurrently on and the Grid is laid out differently from what you may be used to..
Begin by drawing the left side of the box (shown at the top of the lesson) using
the linecommand. Ignore the hole at this point. You will want to use theDirect Distance Entry
Systemfor this exercise and make sure that you have Ortho (F8)and Osnaps (F3) turned on.
Switch to your right isoplane (F5) and draw the right 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 ellipsecommand. At the command prompt,
press I for isocircle. This will allow you 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 correct center point.
Save your drawing in your CAD folder.

To dimension an isometric drawing, you have to do a few things first. Create a text stylecalled Left, and give it a 30
oobliquing angle, then create another called right with a -
30oobliquing angle. Then create a new dimension style that has the text aligned with the
dimension line. After you have placed a dimension, use the DIMEDITcommand to change theobliquing angle of the dimension + or - 30 degrees. You may also need to use the properties to
change the text in the dimension to left or right depending upon the orientation of the dimension.
