I'm developing a bent spring object, using the TUBE command. I've got the maths working, but unfortunately, the TUBE command puts small creases in the profile as it starts to go over the bend. You will also see some large twists near the apex.
I've have tried playing with the angle parameter, but it has little effect.
I've conferred with some colleagues, who are confident this is either a bug, or beyond the capacity of TUBE to deal with.
I'm not an advanced GDL coder, but if this is one continuous tube around a centre of rotation then perhaps you might get around the graphic problems by creating the end spirals and then infill with a single 360 degree spiral?
This might also help if you haven't already got it...
Hi, you could examine the geometrics by switching the wireframe on. The tube section's orientation needs to be calculated and in some cases knots can appear. By splitting the tube into suitable pieces this problem can be avoided.
