Doing a sweep up a spiral problem

brad.bylls — Thu, 17 Jun 2021 16:49:48 GMT

Since the API does not have the ability to do a coil, I have created a spiral and a sketch to make the coil.

However, it does not work properly.

It starts out as a simple rectangle at the bottom, but as it goes up the path it twists.

I have tried ParallelOrientationType also, but that does not work either.

Below is the code to create the sweep.

# Create a sweep input

sweeps = newComp.features.sweepFeatures

sweepInput = sweeps.createInput(prof, myPath, adsk.fusion.FeatureOperations.NewBodyFeatureOperation)

sweepInput.orientation = adsk.fusion.SweepOrientationTypes.PerpendicularOrientationType

Any help appreciated.

Thank you.

@brad.bylls , You can use a scaled version of your path as a guideRail. It works in UI, so I guess it works with API too.

In the following sample, the profile width is 10mm, the profile path radius is 25mm and the guiderail radius is 30mm. So:

guiderailRadius = profileWidth / 2 + pathRadius

Maybe it's better to use none for profile scaling so we do not have to worry about guideRail radius.

That did it.

Thanks so much.
