Fixing the Sweep is really simple, but your sketch has a number of other problems.
The correct process to start a project like this would be to edit/rotate the canvas so that :
- One key element of the sword on the hand sketch coincides with the origin of the design.
- The center line of the canvas sketch is as horizontal as possible.
then, when you start sketching/tracing the lines of the sword, the starting point will be the origin.
Many of your sketch elements are not properly constrain, so its very easy to break the sketch and ultimately the design so make sure to use constraints.
@jeff_strater It would be interesting to look at this sketch for the Fusion 360 team. Even though there is not really much in the sketch, the performance when sketching, e.g. just moving line ends around is absolutely terrible.
