The Coons Patch entity is surface based on a BSpline Surface which is generated by interpolating between 2-4 BSpline curves whose end points are coincident. The surface is generated by linearly interpolating between the curves (bi-linear) or by cubically interpolating between the curves (bi-cubic) taking into account the tangent information of each curved defined by its adjacent curves. The coon patch entity is edited by modifying its definition curves although the surface itself can be extracted as a BSpline Surface.
Right-Click -> Multiple Selection -> Coons Patch
Create a Coons Patch by selecting 2-4 BSpline Curves whose end points are coincident.
The Coons Patch cannot be edited directly, but by it can be manipulated by editing any of its attached definition curves.
