nurbssurface - PLAXIS 3D Input commands documentation

nurbssurface nrbss

Creates a nurbs surface.
Creates nurbs surface in a specified location from the specified points. It detects a best-fitting plane so it can be used to arbitrarily oriented surfaces.

Text Continuity
"c0" Continuity Only geometric continuity
"g1" Continuity For each point on the curve, the tangent vectors "on the right" and "on the left" are co-linear with the same orientation
"c1" Continuity Continuity of the first derivative. The "c1" curve is also "g1" but, in addition, the tangent vectors "on the right" and "on the left" are equal
"g2" Continuity For each point on the curve, the normalized normal vectors "on the right" and "on the left" are equal
"c2" Continuity Continuity of the second derivative. The "c2" curve is also "g2" but, in addition, the main directions of the curves also match.
"c3" Continuity Continuity of the third derivative
