flexiblity issues

[benwalden]

Take a look at the picture below, it's a rubber bellows to cover a spring & rod assembly to prevent corossion and foreign matter from entering a sealed portion of the movement... That's the easy part.

However, I'm trying to make this bellows flexible in Pro/E WF1 (M170) and I've hit a speed bump. When trying to make to overall length & angle of the bellows flexible, some straight lines become zero length segments and it craps out. Here's the sketch for reference:

Thanks ahead of time for any help!

First thing is your sketch has too much going on. You can acheive your goal by simplifying your sketches. Create the upper and lower features in the first sketch. Then create the bellows afterward. You will have much greater control and...e'hem...flexibility in the regen.


You can let Intent Manager give you equal length assumptions on the bellows and control the amount of compression from the first sketch.

Create a warp feature after your main geometry-driving features... Then use the dimensions of the warp feature to make the part flexible.

looks like the warp feature will work, but I'm going to have to split up the sketch becasue I don't want the base (.800) to flex.


Thanks for the help!

Yep... You should be able to define the 'warp zone' to exclude that portion of the model.

Hey, the warp worked fine, but now I've hit another problem...


When the part is put into an assembly and then an assembly section is made, the "warped" part will not show a cross section and will give the error message :


WARNING: highlighted loop in cross-section A may be incomplete.


Any work arounds?
