Electronic – Altium: problems with generation 3D body with IPC component wizard

3daltiumlibrary

I'm a big fan of this feature embedded in Altium. However some of the component generators have flaws:

Chip resistor and chip capacitor generators making me a wrong component height (despite the "minimum height" setting the resistor appearing too high, and the capacitor is too low)
SOD123FL body have no cathode designator

I think that there should be an editable file which I could edit to correct these errors or a setting section. But I did not find any.

The STEP model created by the Alitum Wizard is not editable, at least inside Altium. Actually you can't modify any STEP model in Altium.

I suppose you could go around this doing this:

It doesn't seem worthy at all.

I would suggest one of the next options:

Searching on the manufacturer website. Some of them provide the 3D model, mainly for connectors.
Searching for the STEP model in these repositories 3D content or TraceParts or https://b2b.partcommunity.com/3d-cad-models/ .
Creating the 3D model in a CAD tool by yourself.

Failing all this, you can create a basic 3D model in Altium extruding basic shapes.
