Scale or transform in a pattern?

[jakerocker1338]

I'm looking for a way to transform when making patterns - both on bodies and in sketches.  Think: spiral pattern of increasing diameter spheres or circles.  It would be 2D in a sketch or 3D for bodies.  It would ideally also have reference points for rotation, direction, or along a path.  This would affect all attributes of the original sketch object or body with an extensible option to add another pattern with transform on otherwise unconstrained subattributes.

Example: increasing diamter spiral staircase around an established column - start with bottom stair - set pattern to move up and rotate around center of column - also scale the length of the stair. For this example, the stair will also have a gear orthogonal to the end face which you could subsequently chose to rotate a set angle.

Is there a good way to do something like this?  If not, let me know to add it to the requested features.

PS - still having trouble with symmetrical patterns moving and not suppressing correct instances.

Thanks

The extensible part would be that the gear I was talking about rotating would/could rotate once before copy or rotate additionally per instance.

Unfortunately, there is no automatic way to do this in Fusion today.  The best that I can think of is:  Make the pattern that you want as a Feature or Body pattern, then use the Scale command to scale each instance by whatever factor you want.  Here is a circular pattern with a different scale applied to each instance:

The problem with this approach is that if you add instances, you have to manually scale the new instances, so it's not automatic.

Hey its been half a decade since this was brought up is there now a method for this in fusion 360?

Hi,

Please show a use case so that we can deal with it in a targeted manner.

Please share the file.

No, there is no feature set for this in Fusion 360 and this only cones up very rarely.

I believe, however that this can easily be done with Autodesk Dynamo.

As you can see when following the link Dynamo is way too expensive for occasional use and AFAIK there is no hobby or free-for-non-commercial-use license available.
