About time to fix the "Radius is too small or number of segments is too large for given angle."?

@Anssi

a nifty way to calculate the optimum number of circle and arc segments for a given radius and printer resolution?

How many points for a smooth curve?

If you’ve ever 3D printed some sort of circular shape, you will notice the faceted look you get if not enough points are used. A larger radius will require more points than a smaller radius, but how do you determine how many are good enough? The answer is pretty straightforward, but the calculations may be beyond some users. In order to facilitate this, I’ve created a simple plugin that will tell you how many segments you need to specify for either a full circle or an arc, given the radius, the …

Arcs and Circle line segments for CNC

Is there a way to automatically draw arcs and circles with the appropriate number of line segments for designs that will eventually go to a CNC? I know you can many change the number of segments when creating arcs and circles, but calculating for each one is a real pain. IS there a setting for this? An extension that automatically computes this when drawing?
