Hi folks,

i want to draw a line in 2D or 3D in an ark form of 180 degree (half round line). the function draw_line seems to be not very useful in that case.

I will be very gratefull for any sugestion.

thanks in advance

draw_line is exactly what you are looking for. Just create a draw_circle function where you specify radius, starting angle, arc and number of iterations/ nodes, which implements a for loop that uses sinus and cosinus to get the appropriate node positions on the circle (in relation to starting angle, arc and max iterations) and draw_line between consecutive nodes.

OK, thanks a lot.
Will try it that way.

Cheers
