| − | 1. 2D curve editing operations on the parameter space. This is used for surface trimming and loops. Now the project only supports creating simple 2D lines.

| |
| − | 2. Improve support for trim and loop on surfaces in Brep. Now the project supports NURBS surface editing operations. But we can't precisely trim the surface. Functions needed include finding 2 parameters and a geometric intersection line of two NURBS surfaces, the intersection between two parameter/geometry curves, and so on.

| − | 3. Simplify user operations. For example, users need to manually input the directions of the curves while creating loops.

| − | These can be automatically judged to reduce user input.
