(hoping one of our devs chimes in) the correct fix (or workaround depending on your point of view) as you pointed out is to untrim, keep your e…

if i rectangular-sub-Select the area i get: 1 edge, 2 vertices added to selection. so there is a really tiny (0-length ?) edge curve index 9 curve2d[ 0]: TL_NurbsCurve domain(-3.5,-0) start(-31.25,-14.1) end(-31.25,-14.1) curve2d[ 1]: TL_NurbsCurve domain(-12,-3) start(-31.25,-14.1) end(-31.25,…
