Create a Blend with a constant radius with 2 guide-line. <fshape> sets the type of fillet surface. The -- default value is Convert_TgtThetaOver2 (classical -- nurbs -- representation of circles). ChFi3d_QuasiAngular -- corresponds to a nurbs representation of circles -- which parameterisation matches the circle one. -- ChFi3d_Polynomial corresponds to a polynomial -- representation of circles. . | |
