STL will not slice unless Wall Generator property is changed

I created a button with text on it using FreeCAD and the STL shows fine in WIndows 3D viewer and I even uploaded to STL to a few sites to check for issues and they all said the STL is OK.

When I place the STL in CP version 6.3.0.3420, it looks OK:

I then render the object and it comes out looking like this:

I loaded the STL into CP version 5.1.7.10514 and when rendered it looks OK. So there is a difference between how 6.x slices a model and how 5.x does it, and it seems to be not as good.

I found that in CP version 6.3.0.3420, if I change the Wall Generator property from Classic to Arachne, the model renders correctly.

Just thought I’d let everyone know what I found in case someone has the exact same issue.

STL attached.
