45 chamfer

[htm01]

never ran into this before, when adding a 45 deg chamfer in wire or solid if it's a flat to a curve it doesn't come out to a 45deg

if i draw a vertical  line at the intersection it does the 45

is it making the 45 tangent to the curve intersection point?

Does the angle change if you make a bigger chamfer?

yes

Other cam software does it too. It must average it.

Ive seen customer models like that where they called 45 on the print.

Correct- the intersection of the chamfer at the tangent of the arc is affecting the outcome. If you're adding an equal Width+height chamfer to any corner that isn't a true 90 degrees, it has to pick a median. Here you know the answer you want- you'd like the chamfer to remain 45 to the bottom edge- but to the software, 45 to the tangent of the arc rather than your bottom edge would be just as valid- so it's a case where you need a very specific relationship for the chamfer angle and should draw it out.

doesn't do that in Solidworks, would think that the 45 deg is locked in

i don't have SW for MC loaded will have the other programmer try it when he's back from vacation

If you're adding via the 1 or 2 distances method, then you aren't actually asking that it respect a 45 to either edge- you're asking for specific conditions for the bestfit of the chamfer between the two edges you're applying the chamfer to.

but did the same function in both systems, i d 

if you do 1d with angle it doesn't let you select an arc
