I have made a model which suddenly appears like it is hollow. But it still behaves like a solid model (weigth normal, selecting is normal).
After I made some changes to the model it somehow changed to a hollow looking model. And now even after the first extrude action it already looks hollow.
It must be a graphical thing I would say. Updating, cleanup and restarting doesn't help.
What could it be?
Solved! Go to Solution.
Since you have already checked if it is a solid body so as a precaution can you run an Examine Geometry check (provided it is a graphical issue) on your model? Look for any sort of geometric inconsistency.
Also if you export your solid model in another part file...do you still get the same graphics issue?
The examine Geometry didn't find any errors on the concerning extrude.
I have exported it to step and imported it again. The step file model is just fine. A solid model.
