At Rill Architects we run ArchiCAD on macOS. If you work at Rill, this is your stuff. If you don't, but you work in ArchiCAD, you may find something interesting. Anybody else, I don't know.

The only difference between a perspective and an axon is in the 3D projection settings. And you usually do more than one axon, so you'll probably want to know about that.

1. Image | 3D Projection Settings (Cmd+1). Parallel Projection Settings. If the box in perspective mode, click the parallel button.


3D Projection Settings (Cmd+1)

2. The projection is probably random. Get it in shape by clicking the projection flyout and selecting 'isometric axonometry'.



Then move the camera around to the bottom. The azimuth should be 270�.



3. The default angle for this axon is 30�. This shows more wall and less roof, so it's good. We don't use it. A 45� axon shows nothing but roof and barely looks like a house. We use that.

To change the angle, substitute 45 for 30 in the X and Y fields.


I know. Well, let's do 45 anyway.

Set the angle with the camera at 270� since it makes the numbers easier. Then you can roll the camera to the other sides and leave the angles alone.

4. OK the projection settings and go to the 3D window. Activate the Marquee tool, and select the flat (4th) geometry method. Draw a marquee around what you want to present.

5. Copy. Make sure you have 'Edges' and 'Hatching lines' (assuming you are displaying the vectorial hatching). Check the 'Remove Redundant Lines' box. OK. Wait.

6. If you haven't got it already, create a detail window with the ID 'Ax1'. (You'll need Ax2, 3, etc. if making more axons.) Open the window and paste. Make sure you choose 'Original Location'. Make any line edits you want.

7. Place a drawing title object.

OK that one is done.

8. Return to 3D projection settings. Move the camera to the right side (0�).



OK the box and return to 3D. Do the whole copy-paste-title thing again in detail window Ax2.

Two down.

9. Repeat, moving the camera 90� each time, to the top (90�), and the left side (180�).
