Unless I am missing the point, at present, in Shapr3D, you can’t move spline points from their native work plane to other planes like Y or Z.
This feature would greatly aid in quick and easy complex object modeling, a time-saving benefit for architects and designers familiar with similar tools in software like AutoCAD, Revit, and Rhino.
Shapr3D already has precision drawing tools and features like lofting and sweeping in place. Overcoming this limitation is key to streamlined architectural surface object creation.
