Problem Importing Part into Assembly

[tsopkow]

I am trying to create an assembly hardware using .stp files I downloaded from a vendors site. Some items import in with no problems and I am able to create constraints. Others however give me the attached error message.

I do notice that if I import the files through the file menu the files that work have a blue box icon in treeview and the ones that don't have a part icon.

Could somebody explain to me what I need to do to get these parts usable in an assembly?

Thanks

My apologies.

Here is my FreeCAD info

OS: Windows 10
Word size of OS: 64-bit
Word size of FreeCAD: 64-bit
Version: 0.17.13541 (Git)
Build type: Release

Try a newer FreeCAD. I tested the first file and that's what I got:

Does it work the same for you? I see the Part icons in the tree, but there are blue blocks inside
The "good" file has a flat structure in the tree. Almost for sure there was a change in step import since v0.17. My version is:
OS: "Fedora release 28 (Twenty Eight)"
Word size of OS: 64-bit
Word size of FreeCAD: 64-bit
Version: 0.18.15263 (Git)
Build type: Unknown

Qt version: 4.8.7
Coin version: 3.1.3
OCC version: 6.9.1.oce-0.18

P.S. I don't remember anyone using FreeCAD to put together I/O panels - would be great if you could share some details of your work (no pressure, I understand not everything can be shared).

The error is self explanatory, Przemov's video shows the problem file contains more than one visible part.

You can do one of two things, make all but one part invisible, and make visible and import each part in turn.

Or create a sub-Assembly using the method above and import that.

Not sure if it is possible to create a part compound for import into assembly, you could try!

HTH Steve.

Actually, the real issue here is not with FreeCAD, it's with the Assembly2 add-on which AFAIK has not been updated to recognize the Part container (yellow step icon) introduced in v0.17. This container is used to organize STEP assemblies.

Assembly2 is no longer actively developed, you should have a look at A2Plus, a fork which is in active development. I believe it supports the Part container, but I'm not 100% certain.

Hi @NormandC,
A2plus supports Part- and Body-Containers. Edit: During importing parts /Edit Also it is able to import more than one visible object.

@tsopkow: It is worth to try A2plus. But it is unfortunately not compatible anymore with Assembly2. So your assemblies have to be done completely new, starting with an empty file and new imports.

Thanks for the confirmation kbwbe! I've briefly tested your workbench some time ago but my time was limited. I hope to spend more time testing it over the coming Holidays.
