Help me ! How to pattern this feature

[dat nguyen]

Hi ! every one here. I try to pattern the cut around A_2, but i can't. Please helpme

And this is my file : 2008-08-15_072532_hosho1.prt.zip

Is this what you mean??





if so, Copy the surfs of the cut , then make a patttern of the copy.


then just solidify... (and make a reference pattern of the solidify feature!)

Thanks tobbo!Buti use W2 so i can't open your file.Follow guide, i getresult below .





Which thing i concernis the side of yellow arrow. The molidify 'll be wrong if wecontinue this job ! How can we solve this problem ?

 

[tobbo]

Sorry, but i dont have WF2 here.

Anyway, please look at my attached pics, in the top pic i show you the surfs that i copy. In the lower pic you see the solidify feature.


Is this for any help? Otherwise i can see if i can fix a WF2 file for you!!


good luck!! // Tobias

Here is a WF2 file for you to take a look at.

this seems to be one of the things that Pro-E doesn't seem to do well. correct me if I'm wrong, but why won't a pattern of the solid geometry work but if you copy the surface geometry and pattern that it will work? fundamentally shouldn't it be the same thing?

I've had instances before where I had to do some rather strange things to get a pattern to actually work and I generally try to avoid them whenever possible.

You need to tie the cut to a movable datum feature to get it to pattern. Make a datum plane through the axis and use an angular reference to constrain it. Then constrain you cut to that. Whe you try to pattern that feature the angular dimention should come up.

Trouble with ProE is that it triesto pattern sketch + parameters + references and often gets stuck with this approach. There's not enough "intelligence" to let go of certain contraints and just copy the resulting feature. Simply said : capture design intent. There's a lot of improvement in WF2 but there's still things that go way easier in other programs.

Never use an orientation created in sketcher to use as your angular reference. Always make datum-on-the-fly. That said, solid geometry still encounters difficulty sue to edge and surfaces IDs changing throughout the patter. The most stable method is to create all your geometry including radii, then use a copied seed & boundary surface to maiantain updated to original geometry, then carry out a surface trnasform with distance '0'. Then use this to produce your pattern. Finally, solidify the first surface feature and then you should be able to reference pattern.

Thankall.I couldnot pattern the group because i keptsolidyfy_2 feature in it.Just need to move the solidyfy_2 goout

thenthe pattern'll run !
