Multiple .step file export driven by a changing variable in sketch.

[tireblower]

Hello everyone!

I have a question - 

Is it possible to add a variable in the sketch, produce all of the extrusions, etc, to get the solids, and then, when exporting the .step files out, have the .step files export with that variable changing its value?

Let's say I had made that variable for the length of the workpiece, ( originally 30mm let's say ) and then the first .step file export would have 30mm as the workpiece length, then the next as 29mm as the workpiece length, then the next 28mm, and so on, based on my pre-set change in the variable.

So here I would be left with 30 .step files, with workpiece length varying from 30mm to 1 mm.

Thank you in advance!

Hi @tireblower .

Does "variable in sketch" mean letters in the sketch?

For now, I have created a sample that exports a Step file while varying the extrusion height from 30 to 1.
Please open the attached f3d and then run the script.

        # query
        res = getExportFolder()
        if len(res) < 1:
            return
