2d&3d curves


New member
your question is very vague. list any specific issue. however, you can create curves in lot of ways. easiest would be sketch a curve which would be obviously 2d. you can chose points or vertices to create 3d curves, can chose edges of solid/surface geometry tocreate curves (either splines or curves with bend radii).

Hi Try this in create curve using equation

/* For cylindrical coordinate system, enter parametric equation

theta = t*360*5
r = theta^.5
z = 0
/*5 is the amount of circles
