Viewport background mask

[Anonymous]

It would be great if when placing a viewport on top of another viewport it would automatically mask out the viewport in the background (or at least have an option for background mask). From what I gather this can be done with wipeout and viewport clipping, etc. but it is somewhat of a pain. Also, it would be nice to have shapes (circle) as viewport options as well.

Because you put multiple ideas in a single post, I'm going to provide a solution to one of those ideas. If you still want the other ideas, make them into seperate posts so they can be better tracked.

For the viewport, you can make a viewport from a circle (using Civil 3D 2016). In the MView command, there is an option for polygonal. Use two arcs to set the circle.

Circular viewport:

1. Make a viewport
2. Make a circle
3. Use the VPCLIP command to clip the viewport to the circle.

Haha, its great that the minor thrown in question was answered but not the main question.

Also. Draw outer polygon for Viewport. Draw Circle or other polygon for inner hole (wipeout) inside the first polygon. Convert both entities to Regions. Subtract inner reigon from outer region. Create Viewport from resulting Region. You have your hole.

Still would be good to have this automated.

Let's not try to ignore the elephant in the room ...Viewport background mask property is desperately needed.

Worked perfectly. Thanks!

Try changing Visual Style of viewport you want to have with "background mask" mode. 2D wireframe in my case works as transparent, others make viewport "filled". You must "enter" viewport to change it (double click inside frame)
