Why isn't it possible to pattern a spline?

I'm trying to remove drawer edges and I'm wanting to do a linear pattern in the sketch. Would this process be better done at the feature level?

    How do you pattern a feature when you can only pattern parts, it seems.

    In the pattern feature, select feature pattern instead of part.

    linear pattern in sketch doesn't seem to have a feature pattern option (or any options). and yet it cannot linear pattern a spline

    I think that's also the case with SolidWorks, so it's probably a Parasolid Kernel limitation. Using '3D Fit Spline' you can convert your spline into a 'curve' and that then can be patterned.

    @CADNurd I would use Composite Curve instead to avoid any issues with approximations from 3D fit spline.

    I'm sad to report that you can pattern style splines in SolidWorks (I checked in 2025). You can also pattern regular splines, but not parametrically.

    Edit: Sad because it means it's not a Parasolid kernel problem.

    You can also pattern the sketch feature itself. Not the sketch pattern tool, the pattern feature (set to "feature") and picking the sketch containing the spline.

    Useful. Will try to remember that. Have you always known this workaround, or did you just discover it today? None of the LLMs seem to know about it.

    It works, I've also used that to create brake discs in the past. Many times, creating a solid and then patterning that is the better approach, but there may be times where we don't want that.

    Don't forget this is a feature pattern. Else it won't let you select a sketch.
