Question

accelerated pattern

Hi,

I have to manage sheet metal parts with big patterns (air flow cuts).

Regenerate them is very long.

Patterns are already set to identical".

I've seen in the pass a method to accelerate pattern regenerations.

It was something like making surface quilt and cut by solidify.

I've made unsuccessful trails (it's longer).

Does someone knows how to do ?

Thanks

I think you are referring to the "Turbo Pattern" as shown in this video.  Never tried it in sheet metal.  Let us know if it works.

Select a surface of the feature.

Press and hold Shift, select bounding surface and let go of shift.  You now have all  surfaces connected to the initial surface upto the bounding surface.

Press and hold Shift, select opposite bounding surface and let go.  You now have all of the surfaces of the feature.  This will update if you change the feature adding or removing surfaces except for deleting the original surface.

Press Ctrl+C the Ctrl+V to create a copy of the surface.

Pattern the surface.  I did 9X9 (81 holes)

Select the first surface and Solidify (cut).  I had to add a 0 degree flat to give it something to cut.  Sometimes it works without adding material, sometimes it doesn't.

Pattern the Solidify.

This will regenerate much faster.

Thank you very much,

First method will be helpful for a lot of things.

In my sheet metal part, second method help me a little bit.

I can copy the surface made by the cut but can't do solidify with this one.

Even after unbend bend...

So, I've made a surface quilt instead of cut.

Then I can repeat it.  > Solidify first surface > repeat solidify.

However, regeneration process is improved about 7%.

(I've expected a little bit more).

Thanks,

Kevin has a lot of great information.  It is all about what has to happened in the regeneration.

We've done a "Borg cube" discussion where we realized how much work intersecting solids create.

A non-conventional means may be to apply a "thickness" at the end of the quilt development.

Rounds have a similar issue.  A fully rounded, highly ribbed plastic part can take hours to regenerate on just this one feature.

It belongs at the end and suppressed for most of the revision time.  Simplified reps might help here too.
