With the new update for Fusion 360, it has become difficult to generate bodies from mesh sections using Fit Curves to Mesh Sections. The earlier versions allowed the process to be quick and easy by keeping it under the sketch tab, which allowed to choose different curves from the outside (workspace).
In the new version, it is first necessary to enter the sketch mode and click a sketch from the browser, which allows us to choose only a particular mesh section. Moreover, it has been resulting in the fitted curves to be displaced from the curve to be traced.
It would be nice to revert this feature as in the previous version.
