Hello,
The 3D sketching capabilities of F360 are interesting but they don't match the flexibility and ease of use of more traditional nurbs modelers. In those apps I'm able to create a 3d wireframe with splines, arcs, lines, etc, that set the basic patch layout for building surfaces in a fraction of the time that it takes me to do it in F360.
But there's also an emerging trend of 3D sketching tools such as the about to be released Umake app ( https://www.umake.xyz )that allows designers to build 3d wireframes even more intuitively and faster. I've been testing this particular app and its workflow with Fusion 360º and was surprised to find that Fusion could not import wires from IGES or STEP files, but only 3D surfaces or solids.
From all the 3D apps that I use, F360 is the only one that don't have this feature.
So my suggestion is that Fusion 360º should be able to import wire 3d data from IGES and STEP files.
This feature will help optimize the design workflow by allowing the usage of 3D wires made in other software in early stages of concept exploration.
Best regards,
Carlos
