Cut/family problem

[Aleksander_Bachrouch]

Hi everyone!
I’m running into an issue in my workflow related to cutting elements.
I created a simple family, like this:

My goal was to cut it inside Revit using Generic Models. However, for some reason, I couldn’t perform the cut on the bottom brep. To work around this, I exported the cutter solids to Rhino and used a Boolean Difference on the initial brep.
Here are the cutters:

And here’s the result - a valid polysurface in Rhino:

But when I create a New Component Family in Revit, something seems wrong with the geometry.

This isn’t the first time I’ve faced a similar issue, and I suspect it might be related to tolerances, but honestly, I’m not sure what’s causing it.

With direct Shape it does come through

You can also create separate void family to cut the elements inside the Revit

Thank you @MSAwan for the reply. This morning I found out that my initial geometry was incorrect. There was one inaccurate section, that caused the problem. In this case, saying “trash in, trash out” proved true in full.
