Controlling multiple asymmetric chamfers (NX5)

[speedster29]

Hi all,

In NX 5.0.4.1, sometimes when adding more than one asymmetric chamfer in the same feature, one or more of them will not be the correct direction, meaning the short side and the long side need to be swapped. However, the Reverse Direction toggle flips all the chamfers sides together. Is there a way to control these individually?

This topic has been discussed before and basically there is no 100% sure-fire way of ensuring that each selected edge, which is to be chamfered, has the same sense of 'up & down' as it were. The best that we can do is try to at least keep pairs of adjacent edges consistent, but when the first edge has no link to the second edge, all bets are off as to how the software should interpret the 'intended' result.

In other words, the best way to control them individually is to create them individually. ;-)

For the absolute most control, YES. But if you can leverage adjacent pairs of edges, this can help minimize the number of features created.

Maybe it could be possible to imagine a right or left selection to indicate the short side ?

Didier,

It's good that you're thinking about this but there is a now a reverse vector in the command with a preview which helps control the output unless you select multiple unconnected edges. The thing is if you add extra keystrokes and you always have to use them even if you probably don't have need of them then that becomes counter intuitive, but if you just hit apply you stay in the dialog and simply pick the next edge. Okay so the tool isn't designed to do separate chamfers inside a single feature, but chances are it is easier to do one at a time if you stick within those limitations. Going outside the limitations makes for complexity and that could actually make things worse.
