1. Create a New empty document.
2. Ensure "Enable STEP compound merge" is OFF in Import/Export (STEP) preferences.
3. Import the STEP file (You will be prompted to Save the file, pick a name)
4. You will see three bodies (Parts?) created.
5. Create a new Body
6. Try dragging one of the parts (I am using the small Top part) into the Body
7. Error pop-up

Code: Select all

Bad Object "Unnamed#Part__Feature002 (Part::Feature) linked to the Origin of Unnamed#Body"

I can't seem to make it work although someone on Reddit tried it and it apparently worked for them.

I must be doing something wrong but I don't know what that might be.

for me, it works very well
pay attention to the reported overlap

[easyw-fc]

to be able to compare the result we need to apply the same STEP import options

EDIT:
a workaround is to add a binder

binding-option.FCStd

Yes, it is that very overlap which prompted me to try this.

Did you do the exact same steps I did? If not, then what steps did you follow? If Yes, then what could be the difference that causes mine to fail?

Can you elaborate a bit and explain what you mean?

Did you try the same steps that I did and get different results? If so, what could be the difference?

Is that error a bug or user error in your opinion? I don’t rule out user error as I am fairly new to Freecad.

the other users should have used the same STEP import option to be able to compare their results with your
go to FC Preferences

just disable the first checkbox in the 'Import' section

same results with the same error

a bug imo
