Viewport problems

[Tobias]

Here is the issue I am having now:

I have a viewport made up of 3 layers, all containing roof objects (a combination of Roofs and roof slabs. The settings of the viewport are top/plan and wireframe

Everything looks as it should as long as the actual design layers are set to Top/Plan and Unified view. If for whatever reason one/all or some of the actual design layers are not in Top/Plan or unified view, the viewport no longer displays correctly. To get the viewport to display correctly, I usually need to navigate to 'Edit Design Layer' from within the viewport.

Took me a long time to figure out what was up, and then how to fix it.

No one is experiencing this? It showed up in a completely different file. What a PITA.

Also, floor objects tend to disappear when I zoom in in a viewport, another pain.

Am I the only one?

I have problems with viewports and OpenGL.

Sometimes the viewports just wont render properly. The only solution I have found is to redo the viewport or render it in another render mode. Very tedious.

I had no such problems with 2008, 2009 and I have no idea what causes it.

I must say I have had a lot more problems across the board (rendering, exporting boolean ops etc) since the layer/screen plane was introduced and I can't help thinking that is still not been incorporated properly.

No help, I know, but you're not alone!!

I have had problems with OpenGL not rendering properly. I usually resort to using the Flyover tool to "jiggle" it, and eventually it renders.
