Isometric dimensions in a 2D drawing.

When you create isometric drawings (2D) in AutoCAD, use the ISOPLANE command to switch isometric planes (Left/Top/Right) while drawing. For the isometric cursor you need to use the SNAP command and to set its Style to "Isometric".

For dimensioning then use the aligned dimensions - DIMALIGNED, modified by obliquing (oblique angle 30°/60°/330° depending on the isoplane) - see DIMEDIT, Oblique. With DIMEDIT Rotate you can edit rotation of the dimension text (the angle 0.001 makes it vertical).

You can also align the dimension text - just use DDEDIT to and change the oblique angle of the text (30°/60°/330°).
