IFC4 problems with transparancy

BvanDalsum

For several weeks now, we have been exporting ifc4 files.
We are now running into and number of problems.
the view of some elements seem transparent while they are not, just from which angle you look at it.
And some elements are no longer in the same position.
Here are some screenshots

here the Slab is clearly visible
from this angle the slab is transparent
the button should be on the control box

Hi, are you using Revit? and is the button a nested family in the box family?

BvanDalsum

@bariscanpolat yes it is a nested family in Revit

if the nested family has some mechanical or electrical connections, the location of the nested family explodes. Although I don’t know if this is the case in this

@BvanDalsum said in IFC4 problems with transparancy:

This slab seems to have inverted faces. Might be problem of the IFC file or Solibri IFC importing.
Make this setting OFF to see both sides

For misplaced button

check that you have the latest version Solibri 24.9.0
If it is still misplaced, could you send a small IFC having this problem to Solibri support.

@Matti-Kannala , thnx.
it was back face culling indeed.
Normaly i leave the box unchecked but this time it wasn’t.

Fortunately, it was something simple I overlooked
