|0002369||FreeCAD||[All Projects] General||public||2015-12-13 15:13||2017-07-12 11:37|
|Target Version||Fixed in Version||0.17|
|Summary||0002369: STEP import is not grouping parts|
|Description||.step file imports all the internal parts (not sure what's the proper term for these) into single flat list and doesn't perform any grouping.|
|Steps To Reproduce||1. Import step file|
2. Observe the list of elements in "Labels & Attributes" section:
Under "Application -> Unnamed" there's a flat list of all the lowest-level objects defined in the file.
And so on..
When importing the same file in Solidworks, the object list contains a tree of properly grouped and named elements (Board, C57, C56, C55, LC1, C54, and so on).
|Additional Information||Seems like the STEP import is built on top of https://github.com/stepcode/stepcode but it's now outdated.|
Per the forum thread:
"Freecad does not use stepcode but the occ step importer. And it does not group the imports because there is no functionality for that available in Freecad, hence groups are ignored."

||@plaes do you mind re-uploading step file and screenshots ? (I know it was a long while ago but since then we had a backup failure for the tracker and lost attachments). Thanks!|
In FreeCAD there is a hidden function to get the structure of a STEP or IGES file (or better the structure of the ocaf document). You can load it with:
which shows a tree with all the content. Does anybody know how to get the grouping information out of this?
@plaes in the bug report you said that SW shows the grouping properly. How many groups are there and how many levels? Maybe an image would help.
I tried the file with CADExchanger which shows also some group structure but they are labeled "=> [0:1:1:2]" and so on but not "Board", "C57", ...
"The URL of the step file is at http://terzo.acmesystems.it/download/mechanicals/arietta.step
Thanks to vejmarie's p:FreeCAD:871: FC now groups parts. Thanks!
