Pi-angle Rotate Extrude Error
The console prints the following error for multiple points when I try to extrude-rotate a half circle, at an angle of Pi or multiple of Pi (to form a sphere).
Error : Could not find extruded vertex (0, 0.9427765746659805, -0.4803686579795019) Error : Could not find extruded vertex (0, 0.9688626331215779, -0.4936601686396281) Error : Could not find extruded vertex (0, 0.9427765746659805, -0.4803686579795019) Error : Could not find extruded vertex (0, 0.9688626331215779, -0.4936601686396281) Error : Could not find extruded vertex (0, 1.006315644616927, -0.3269717735633536) ...
To get around this it seems that users have to use an angle of 2*Pi/3 three times. This is how I am using the extrude-rotate routine. There's three of these:
s2=news;
Extrude {{1, 0, 0}, {0, 0, 0}, angle} { //Surface{41}; Surface{s2-1}; Layers{20}; Recombine; }
Why do I get that error when I make angle=2*Pi?
