Sketch circular pattern not updating when changing parameter

[glpontus]

I have a parametric design with a rotating pattern. Inside the rotating pattern is a spline. The problem is that the spline does not update properly when the parameters are changed. If I open the "Edit Circular Pattern" and close it again it updates properly.

In the picture the top inner spline is the correct one, the rest five have not been updated.

I can share the design if someone want to inspect it.

Hi,

From text and screenshot I can´t see the conditions.

Therefore I have to look at.

Please share your Design.

I ripped out the component from a bigger design.

It's available at https://a360.co/2VQRDeO

It's the parameter numTeeth_1 that should be modified keep it above 240 or some parts degenerate.

It's the spline in "Sketch3" that does not update.

The design is a bit heavy, it takes a few seconds to update the parameter.

I tried adding the "arms" (what are they called? the lines defining the bend) of the spline to the circular pattern but get some a "Computer Failed" warning instead.

Sketch1 is not fully defined.

It is generally preferable to pattern Bodies or Features rather than sketch elements.

You might be right, better to pattern bodies instead. It's easier to get all the details included

.

It seems reasonable to expect the feature "Circular Pattern" in sketches to work properly though.
