Small tangential arcs
-
Hi. I experienced some problems in drawing small arcs with the plain SU arc tool. So I thought it would be worthwhile to find out the limits of the tool. Got as low as an arc with a radius of 2.6 mm. Trying to produce something smaller, resulted in corrupted geometry or line segments, but not an arc.
Are there ways of stretching a bit the limits of a regular arc? Hint: Scaling doesn't help.

I guess the number of segments does matter. Did not check that though.
You are correct, the arc instantly explodes at small radii. Resulting the first endpoints nearest to the original lines to snap to them.
How to stretch the limits? Do not use the straight way to create the small radius arc.
(I didn't try scaling down. You said that didn't work)
I just made a tangent arc with radius o.2mm by creating a larger one that is "accepted" by SU and then entered the smaller radius in 'Entity Info'. The arc stays tangent but adjusts the radius. -

That works. I arrived at the same level of 0.0002 m by using your trick... and that's good enough for our purposes. - Thanks for good advice.
