Have a model created from which you can create a section and 3D view perspective.

1. Using the default 3D view that is in the project browser create a duplicate of this view.  Select the view then use the secondary mouse button to “Duplicate”
2. Select the new Copy of the view created and using the secondary mouse button rename the view.(ex: 3D Axonometric View)
3. Go to a plan view to create a new Section for a particular part of the model. (ie: Building  Section, Wall section)
4. Rename the section (ie: Axonometric Section) in the same manner that the 3D view was renamed.
5. Make the 3D Axonometric view in the project browser active by double clicking the name in the project browser.
6. Go to the View pull down menu and select “Orient” → ”To Other View” tool.
7. Select the name of the section that was just created from the “Orient to Other View” dialogue box.
8. The new active view will look just like the section view that was created before; the biggest difference will be when you select the “Dynamically Modify View tool” and select the Shift Key and hold down the scroll wheel on your mouse.
9. This will activate the rotate command and now you will see the section created from an axonometric view perspective.
