Trouble Scaling after copying and moving component.

[alfredordz86]

Hi guys, total beginner writing scripts here.

I'm trying to copy, move and rotate a body and then scale the new body in its new position. I didn't have much trobule moving it a few inches in the x axis and rotating it 90 degrees (see screenshot) but I've been stuck for hours trying to scale it. I get RuntimeError: 2 : InternalValidationError : Utils::getObjectPath(obj.get(), objPath, nullptr, path)  (line 80). I'm totally lost here, I'd really appreciate some input.

Thanks!

Hi @alfredordz86 ,

The ScaleFeatureInput need to be created with the parent component of the body.

So, in you code replace line 71 with this:

scales = baseBodyCopy.parentComponent.features.scaleFeatures

This solve your problem.

Hope this can help.

Jorge

Yes!!! I had been stuck for hours with this. I'm still starting to understand how everything works in Python.

Muchas gracias mi estimado Jorge.
