3D STEP file not showing in Footprint editor 3D Models 9.0.3

Layout 3D Models

Hi All,

I’ve been using Kicad since 7.0 and created multiple PCBs with custom components, and full populated 3D models. This is the first time I ran into this issue that can’t be solved by converting the 3D model. Tried in Kicad 8.0.5 and 9.0.3

I want to add a STEP file from a Kingbright LED to my footprint but I can’t get it to show.
Other step files in the same folders do show.
I’ve tried:

  • Different folders
  • Importing the STEP in freecad and exporting it again
  • Converting it to IGS
  • Converting it to IGS and back to STEP
    Etc

If I open in Freecad coordinates are 0,0,0

This is the issue

Step/IGS can be downloaded here

I wanted to attach the STEP in this forum, but can’t do that as a new user.

Please let me know what I’m doing wrong…

The model looks like it’s centred really far away from the origin, over 3m in each of x and y. In FreeCAD:

You can enter the reverse translation and it appears roughly near the footprint origin:

But as the rotation is applied first, it’s not quite that simple (a bit of paper and rotating it front of you may help, plus some trial and error):

You can also re-centre the model in FreeCAD “somehow”, but I don’t have detailed instructions for that to hand.

The origin is meters away from the component . . .

Try this . . .

If it works let me know and I’ll see if I can quickly fix the colours.

Yep that shows the part.
Thanks @RaptorUK and @johnbeard

Sorry, it seems that I’ve misinterpreted freecad coordinates. (I’m not too familiar with freecad yet)
:person_facepalming:t2:

I was looking at base placement information which shows 0,0,0
Apparently when you select a part in the model tree it doesn’t show the coordinates.
But when you hoover the mouse over the actual part it shows the coordinates in the bottom left bar

This one “should” be the correct colours now . . .
