Model disappears behind "curtain," ...reappears in

[Anonymous]

It's as if an invisible plane cuts off our model as we rotate through it.

The model fragments, walls peel off and disappear, then the whole thing vaporizes. Poof. Gone. When we rotate backwards it sometimes reappears in the reverse order of disappearance.

This is an interesting and artistic phenomenon, ...but fatal to presentations to our more serious clients who always seem to expect walls on all the sides of their buildings, ...etc.

The problem is in Open GL where we often edit in the 3D window.

This afternoon we will be showing rendered views and must sacrifice manipulating the model itself, and the tours of the interiors etc.

Sadly, it's often the tours and walk-throughs that sell the designs.

We're using ArchiCAD 10, Intel Mac, 4GB Ram.

There is and object that makes trouble in 3d. Find&destroy it.

My sugestion is to delete half of work and see if the rest works in 3d. If it doesn't work that means the bad object is still there - delete half of the rest and so on until you find it.

If this doesn't help, try to copy-paste your work in a new document.

Instead of deleting, switch on and off layers, and/or use the marquee on half the model, then another half ... and so on ...

Although, the marquee is not always the good thing to do, as some object lose parts of itself when in marquee (for example, the cars from Transportation library)
