To Create a Rectangular Surface Using Four Curves
1. Click
Restyle >
Polynomial Surface >
4 Curves.
2. Select four curves to create a rectangular surface.
To obtain the correct surface, holding down the CTRL key, first select two curves in the first direction and similarly select the other two curves in the second direction.
If the curves do not form a closed loop, the first direction curves are modified so as to form a closed loop for creating the surface. A surface bounded by these curves is created.
