Many sketches are more complicated than necessary. This applies in particular for imported logos or text.

The function Reduce sketch (experimental) function reduces the steps of a sketch as far as possible.

It is best to always use the function manually via the button in Sketcher. The option Reduce sketch history if Sketcher has been accepted (experimental) [Reduce sketch history on applying Sketcher (experimental)] via the settings dialog should only be activated if the function is used frequently (as the calculation takes some time)

If a message History element ... is not constant appears, this means that the sketch uses variables. These cannot be reduced.

If a sketch only contains a circle or rectangle, meaning all steps are relevant, it also cannot be reduced.

Otherwise, the number of elements that can be reduced to how many is specified.
