Compound type shows no sub solid

[Mannshoch]

I got a Step File and if I open it I get this :

In other STEP files Compond Type is a above an entry with 3 green dots and sub solids.

Does this mean that the body is one solid inside a Compound?

Maybe this is related to #78?
Can you share the STEP file for investigation?

@Mannshoch
I don't understand what's the issue with this IGES file. What model tree do you expect?

Mayo v0.9	CAD Assistant v1.6	FreeCad v0.18

Compound indicate that there is something inside which I could not see.

Most other Files I open with Mayo have Shape SOLID

Another one is from https://f3d.app/doc/GALLERY.html (the f3d-data.zip) here in eta_asm.stp
All bodies are Shape SOLID except "HAIR_SPRING" which is Shape COMPOUND. In this case the Body seems could not be viewed in Mayo.

It's empty as well in CAD Assistant:

Also with OpenCascade's Inspector tool:

Do I assume right that the DX20A-68S(50).iges case and the eta_asm.stp have a difference problem?

• DX20A-68S(50).iges - shows as a compound even it is a solid
• eta_asm.stp - miss a solid but does not reflect this case in the tree.
  (May show a red square instead of a blue and have a tooltip "body not available")
