Hello Jackk,
When I hit the VIEW FROM 3D icon, I get a prompt to select a view from the 3D document. It only allows me to select an existing view that I used to create annotations. Clicking on the background does nothing. I could select one of my existing views, but they would make a front or side view (like you said). I did create a view in my 3D model that is oriented in a way that if I select it, it would result in something similar to an isometric view. Only problem with that is there is no 3D annotation on it, and I can’t transfer any annotations to that view because it’s not perpendicular to the geometry that is being dimensioned.
In the case of selecting a capture, that’s no possible, catia wont let me choose them.
