I stretched the part of the sketch and how to remove the feature with another part.
Use the sketch 3 and then cut extrude selecting inner contour.
Sorry,I don't mean this,please unzip the next feature,I want this effect,it should use the sketch c.but I don't know how to do!
For that you would have to delete and recreate the feature (cut extrude) using the S sketch.
Hi,
please make the sketch visible and pre-select "contour selection" in the context menu to use the rectangle of this sketch again to perform the cut.
Use the sketch 3 and then cut extrude selecting inner contour.
