offset a spline

bikr7549bikr7549 Member Posts: 23 ✭✭
Hello,
I am working on making a model for a kids puzzle to 3D print, tracing over a cartoon figure jpeg imported into a sketch. To make the individual puzzle pieces that lock together I planned on making a spline for each part in a sketch and then in another sketch (in a new part) offset the shape of the previous part by some small amount (.50 mm) to create the fit of the joint. But I cannot offset the previous sketch's spline, I get the error 'offset failed, one spline generated multiple offset curves'. Is it not possible to offset a sketched spline?

    Do you need to offset the splines in a sketch? I think this will be easier if you extrude the parts first, then use the Move face feature on the side faces. Like so:

    Excellent Anton, this works perfectly, thank you! I had to experiment a bit to figure out how to use it, but it does exactly what I need to do.

    and, including the example model was a big help to figure this out. Words may have done it, but the model made this much simpler.

    And protip: switch to side view and box-select (right to left) to select all the side faces at once into the move face feature.
