Is there anyone out there who uses the "Undercut Detection" in SW05? Has anyone noticed that it's completely wrong?
Here's a very simple example part:
Here's how the undercut analysis should read for this part:
Dir1 undercut: 0 Dir 2 undercut: 0 Occluded undercut: 0 Straddle undercut: 0 No undercut: 17
But instead, it reads this way:
Dir1 undercut: 5 Dir 2 undercut: 5 Occluded undercut: 0 Straddle undercut: 0 No undercut: 7
Looking at it, the part obviously has no undercut faces when the Front plane is the direction of pull. SW seems to think that the only types of faces that cannot be undercut are faces with no draft, in other words, ALL DRAFTED FACES ARE UNDERCUT.
I don't have any problem with the calculations, I just have a real problem with the classifications. Instead of "Direction 1 undercut", the interface should read "Pulls from Direction 1". Likewise for Direction 2. What most people think of as "undercuts" are actually listed under "Occluded undercut". See "Other" config for occluded undercuts.
Anyway, is there something I'm not getting or has this function always been simply wrong?
