Lost patterns

[appinmi]

I am currently using WF1. and have a problem when I do patterns in manufacturing. I don't have a problem with the first pattern, but when I pattern other features referencing this pattern, they work perfectly, until I start using them for cutter paths.


An example is, to create a series of datum curves, I pattern the first surface, I then create a second surface and pattern that referencing the first pattern. I then merge the two surfaces and pattern the merge. I create a "trajectory" sequence using the curve from the "master" of the pattern. I then create new sequences that use the curves formed from the pattern. After I do this to 4 or 5 of the patterns, that is when the "computer fairy" takes over. The patterned features disappear on the screen, but they show up when I highlight them in the model tree. Proe acts like they are not there, and all but the first sequence "crashes". Sometimes, I can suppress and resumethe patterns, (don't change a thing), and everything is back to normal. However, if I redefine the first sequence , maybe to change the RPM or feed rate, the others crash again until I manually regenerate the patterns.


Has anyone else had this problem? Has it been fixed in WF2. or WF3.? Please, someone shed some light on this.

are you using copy and paste for the trajectory sequences?

No, I create all of the surfaces and datum curves first. Then I create each NC sequence independently, using the appropriate datum curve. I used to use patterning, but Proe got confused when it had to use different Coordinate system for each sequence.

sorry, i meant using copy and paste special on the sequences, since it is referring to patterned geometry. the patterns are not table driven, are they?

upload a sample file for us to see, is that ok?
