3d perspective view suddenly goes blank

[Anonymous]

all,

HELP!!!

My 3d perspective view has suddenly gone completely blank. Ive checked my settings, all is good. The 3d axon works fine, and the 3d perspective even works fine on other workstations. So i know its not a problem with the file. It has to be a setting on my machine. Ive had issues in the past where ive accidentally pressed some hotkey and had to figure out what the hell i did, i figure the same must have happened here.

"Fit in Window" doesnt work, zoom in and out doesnt work. The scroll bars aren't even showing up ( they're shaded, not blue) on the side and bottom.

Im using Archicad 11 on a Mac OS (whatever the latest is). I can always go to someone elses workstation, but this is a serious problem for me. Ive found that having the 3d perspective on the second monitor is like a crutch for me now. Ive searched the forum, and it seems that someone else has had this issue, or at least similar, but no help for me. Any ideas?

I recently had the same issue with Archicad 21. No perspective or sections or elevations.It turns out an array of rafters to a circular turret was the cause. Delete them and it was fine. Put even 1 in and it did not show. Even a roof wizard roof caused the problem. Do not know why

I find that this happens when a roof node ends up way off (infinity) the model. This can occur when the angle of a roof join is incorrectly trimmed.

To see if this is the problem, zoom extents without any tool selected and perform "select all" [CTRL][ A]. All items will be selected. If the model is not visible but a node is selected far from the rest then you have the problem solved. Isolate the errant node, select it using marquis or pointer selection and [delete].

I had this happen spontaneously in my project too, using ArchiCAD 22.

The solution for me was to go to:

View>Elements in 3D View>Filter and Cut Elements in 3D, (the shortcut is Ctrl+Alt+A), then change my settings to "Infinite" from "Limited".

I have never played with these settings before so I have NO idea how my view settings suddenly changed overnight. This was extremely frustrating.
