Hi, I imported a dwg a friend sent me from Archicad. Since I imported it in Rhino 8 I can’t zoom in anymore. Everytime I zoom in the objects disappear at a specific point of zooming. I already deleted the imported objects, created a new layer and imported something else from Allplan, but the problem is still there.. Does anyone know what might be the reason?

Normally this means there is a very large object, or one object a long way away from the other objects that is messing up the limits of the model.
Can you send us the example?
you mean the complete Rhino file?

here’s a screen recording.. maybe this will help..
Try selecting some of the objects you want to zoom in toward and use Zoom Selected.
Zoom Extents in All 4 views. Does the drawing fill up the whole viewport in all 4 or does it get small or disapear?
