Entities missing in CAD blocks in Rhino 8

Hello,

I wanted to report a bug in Rhino 8. When opening some specific DXF files, there are some entities missing from some CAD blocks. When opening the same file in Rhino 7, the same block contains curves that are not visible or do not exist in the Rhino 8 session.

This might be related to changes in the block manager, I’m still investigating the possible reasons for this.

Context: The files were generated using the ExactFlat plug-in for SolidWorks, I’m just using Rhino to view and edit some of the CAD blocks.
