generic perspective going blank

Anonymous — Tue, 18 Aug 2009 14:41:05 GMT

Hey, I was working with a model, and sudenly when I pressed F3 (3d view) there is no model, justa a blank white view... I can see model in generic axonometry, but not in perspective... All other views are working ok.. Does maybe someone know hot to solve that? I'm in a hurry

Hi,
Check either these things:
1-Zoom all/extend
2-Press F2 (black to plan view), then press ESC (maybe more than one), then press F3 again (or F4/F5)
3-Quit AC and open your file again.

Good luck
cheers

non of that worked...
Here is the file.. Is there a way to delete perspective view and create it again, because it seams that that is the only empty view...

It could be that your perspective camera is not pointing at the model.
Check your perspective setting to make sure the view cone is pointing
at the model and the elevation of the camera and target are reasonable.

This happens to me every so often when I use the mouse to zoom when in perspective mode. Somehow the camera and the viewpoint get messed up that way. The way to avoid this is to use "Walk" to get around a perspective view.
As to a solution, bring up your "3D Perspective Settings" dialog box and change the various settings to something really simple. You may see that the distance from camera to eye is really small (in my case 3/8") This is the problem. This should reset the perspective rendering. After that you can bring up your previously saved perspectives.
Let me know if this works.

yeah it worked.. in settings, i had 'E+21' for distance from cammera... have no idea what that E is for... Thank you all

E+21 means 10 on the 21st power.
So you were light years from the model

For one explanation of scientific notation, including the use of "E", see:
Scientific Notation
and scroll down to E notation.

I have issues in 3D once in a blue moon. Sometimes, all my layers are on in 3D, and only the floor slabs and fixtures are showing, for example. I restart archicad and things are ok. When it first happened, I thought I accidentally deleted some layers or walls or something...
