Good news on this front, 2015 R2 begins reducing this restriction!
The following are available in perspective views now:
- Editing tools: Move, Align, Pin and Unpin
- Reset Target tool: Restores the position of the camera target to the center of the field of view
- Toggle between the perspective and parallel representations of the 3D view
Reset Target is a new button when the view's crop region (perspective views) is selected. It places the camera target back at the center of the crop region. It may be useful if the changes you made switching back and forth between view modes has altered the view in a confusing way.
Toggling between view modes is possible through the View Cube and right click. CLICK TO find out more about these enhancements.
The online help documentation specifically notes these items when switching from parallel to perspective view modes.
- If you add elements to the parallel view that are not supported by a perspective view (such as annotations or displacement sets), and select to toggle to the perspective view, a dialog displays.
You have the option of duplicating the view without the non-supported elements and opening the duplicate view in perspective.
- The Toggle to Perspective 3D option is only available from the parallel view if the Crop Region Visible property is selected for the view.
- Some modes are not supported in the perspective view. For example, if you are in Reveal Constraints mode in the parallel view, this mode is automatically closed when switching to perspective.
- Changes made to the View Scale in the parallel view are reset when switching back to perspective.
It's not quite the 60's, the era of free modelling, but it's a start.
