OpenGL/Multi-thread
NfDesign is based on OpenGL and Multi-thread. Multi-thread makes it possible to operate and to edit enormous data comfortably.

Generating Triangle-mesh by Polyline
make triangle-mesh inside closed polyline, make triangle-mesh between 2 polylines, linear-extrude, rotational-extrude, sweep
Editing Triangle-mesh
thicken(defined direction/each vector), smoothen, decrease mesh number, round, separate, extrude(defined direction/each vector), bevel etc
Generating NURBS-surface by NURBS-curve
linear-extrude, rotational-extrude, sweep, make surface between 2 curves, make surface inside 4 curves(Coon's patch), loft, connect, fold, separate, edge-extrude, concentrate on 1 point, round, chamfer, smoothen, 2D offset , 3D offset by control points etc
Conversion between Geometric Entities
