Hi - I have a similar problem to @Anonymous but with a complication. I too cannot offset a curve, and the curved object I want to offset was moved by me from its original position. Problem is, I've only just started using Fusion (<1 week); I'm not sure exactly what I did to move the curved object, but ever since moving it, it has left an identically shaped blue outline behind it; your comment to the previous user seemed to be to move the object back to its original position before off-setting it. But I need the curved object to stay where it is now when I off-set it, I don't want it back in its original position. (It's the fin of a rocket ship booster, and when first drawn was disconnected from the main booster with a big space between the two. I moved it so the two parts would 'join up' and become one booster)
So 2 questions please:
(1) How do I keep the curved object where it is to offset it; and
(2) How do I get rid of the blue outline which really doesn't look like it should be there ?
Any help appreciated. Sorry to be such a novice !
