I've had to import sketches from inkscape (mostly because I can't curve text in plane in Fusion 360) and the sketches come in with many, many points, which slows down the computer far more than any 3D geometry I've ever created. Every line segment and points imports in as fixed. If I select the entire sketch and click "fix/unfix" I assume only so many points can be selected, because not all of the sketch is converted to the unfixed condition. If I try to select all and perform this function again, it will switch back to the fixed condition. I have to manually zoom in and hunt down the slight color difference between the blue and green fix/unfixed sections, select ONLY them, and hit the fix/unfix button again. I will then try to move my sketch, and I'll know I failed in my fixed point/line segment search when the sketch won't move (nothing tells me that some point is fixed!). The best way to find out if there is a fixed point or line segment is to try to ROTATE the sketch- which will rotate all the unfixed line segments and points, but not the fixed. I then note what isn't rotating, go back and try to find those points again.
This is how this can be fixed:
1. Allow highlighting of fixed points. This should be a heavy line, high contrasting color
2. Have the fix and unfixing as SEPARATE toggles. This way, I'm not accidently fixing something that I want to unfix!
This little issue has been the most time consuming part of my prototype design. Every minor change in the prototype requires me to change the curved text of the version label. Because of this import from inkscape combined with this fix/unfix issue, I spend roughly 45minutes to 1.5 HOURS changing the version number on the model.
Best Regards,
