Correcting the orientation of 3D models

[maui]

@Piotr

My problem this time is I still don’t know if that is good suggestion or not.
I decided to have all these parameters set to 0 but I had to learn to use FreeCAD and StepUp what took me significant time.

since the screenshot you posted, it is clear that the suggestion comes from the StepUp WB, then this suggestion is exactly for the use of the StepUp WB

@Piotr

If not using these parameters are practically not mandatory then it looks I lost time on learning how to not use them.

All depends on which level of precision you want in your 3d model design…

@maui

but in KiCAD 3d viewer you can align your model to the footprint only in a approximate way… your alignment is only based on visual feedback; you cannot measure anything in 3D, nor place a model in the center of anything or even a pin in the center of a pad.
The best way is act in a mechanical environment… that is why StepUp was created.

and

@Piotr

What that really means that this one parameter (and only this one) is free?

because in 3D environment you align your model to the footprint… the only variable respect the position of the pads in the footprint is the orientation of anchor reference in plane z

@Piotr

The problem is - what is the right suggestion to OP:

1. To freely use these parameters
2. To learn how to modify a mod

everyone has to find his/her way to work in designing environment…

IMO the best and only way is to use a mechanical integration with all the 3d library aligned to KLC.

@Piotr

If I do something as I was told to do it only that way for years and I don’t understand why I have to do it that way, it just frustrates me.

@Piotr

I remembered where I saw it. It’s still there. In kicadStepUp-cheat-sheet.pdf you see:

who told you that? (see the note on the initial mention few lines above)

Note:
please remember that in kicad very old version (apr 2016) there were not even the 3d preview of the placement of 3d model, so the placement was just try and catch.

Mario’s latest changes use his new 3DViewer to provide the preview in the Footprint Properties dialog. This means the preview now has a board with the component’s footprint on it so you can adjust the location (and scaling of VRML/X3D models).

here the old thread

Testing needed: new 3D plugin

Mario’s latest changes use his new 3DViewer to provide the preview in the Footprint Properties dialog. This means the preview now has a board with the component’s footprint on it so you can adjust the location (and scaling of VRML/X3D models). For those of you who may be using the OCE plugin, just remember that scaling an MCAD model is not a Good Thing™. Wait a day or so for the nightly builds to catch up, or if you build your own code you can just pull in the latest.

Okay, I think I have spent far too much time on this ‘issue’
