Sketch scaling

michael_klinemichael_kline Member Posts: 21 ✭✭
There have been several posts asking about sketch scaling, but most of them have not been touched in a while. I was looking to see if anyone has created a faster work around than starting a new sketch with all of the dimensions based on a variable called "scale factor".

As seen in the attached, I have a fairly complex shape that I would like to scale down to the part I copied it into from the part I drew it in. The sketch has already been modified for scaling, including making the gaps wider and lowering the amount of detail involved. I have also rotated it to the correct angle, but that is a simple transformation.

    Today if a quick re-scale of the sketch wasn't giving desired results I'd probably still resort to scaling the solid part rather than messing with the sketch.  Possibly using a measure distance feature to grab an initial reference so we know what to scale it by.

    Sketch scaling with parameters is almost impossible (for anything other than the simplest of profiles). It works well when there are NO parameters - other than the one you add to control a known dimension. The best solution for scaling complex profiles is exactly as Owen says, extrude the profile and then scale the part. At that point you can re-extract the edges to a new sketch and make any additional modifications as needed.

    Quick Tip - now that sketches can have as a parent a mate connector - it is now possible to move/derive sketches to different planes and angles very easily - WAHOO!!! :)
