Axons/Isometrics in AutoCAD

Several users have noticed that when they create axons or isometrics wih the View/3D View sub commands, the items they create get scaled in distorted ways when plotting from AutoCAD 2005, ADT 3.3 or ADT 2005.

So for example, a 10' X 10' X 10' cube set up with 315 deg on the X axis and 45 deg on the XY produces a cube in paper space that measures accurately in it's viewport in paper space. However, when plotted to an HP DesignJet 800 or an HP LaserJet 4100 or an HP DesignJet 9300, they all plot with distorted dimensions: the X and Y scales to 8.5' and the Z to 9'

Here's some others with the measurements all for a 10' X 10' X 10' cube printed/plotted.

15 deg 15 deg ISO
7.25' 7.25' 9.5'

30 deg 30 deg ISO
8' 8' 8'

45 deg 45 deg

8.5' X 8.5' 7'

 

AutoCAD only supports generation of Isometrics. It is not possible to generate Axons with AutoCAD. You would have to import the 3d models into something like FormZ or ArchiCAD to get an Axon. I think those programs support Axons.

FWIW, Isometric projection is a type of Axonometric.

Any axonometric is drawn by rotating the object away from the plane of projection which will always distort the projected line dimensions.

"The distinguishing feature of axonometric projection, as compared to multiview projection, is the inclined position of the object with respect to the plane of project. Since the principal edges and surfaces of the object are inclined to the plane of projection, the lengths of lthe lines, the sizes of the angles, and the general proportions of the object vary with the infinite number of possible positions in which the object may be placed with respect to the plane of projection."
