is there a way to add a custom seed pattern to the fill pattern?
Any way would be considered i.e. using api, macro, editing dll etc?
Do you mean a custom hole shape used as the seed for a fill pattern? This can be done. Simply create the seed feature first, then start a fill pattern and pick 'Selected features' instead of 'Create seed cut'.
Hi Jamil, using 'create seed cut' aligns the pattern symmetrically but when using 'selected features' symmetry appears to rely on where the feature is positioned. I'm hoping to symmetrically fill an area with rectangular thru cuts without using dims, table driven pattern data or placing initial features and then patterning.
Hmm, I can't help you there. Do you want the pattern to extend off the boundary, or did you want each instance to lie withing the boundary? If you want them to extend past, then I think I have a workaround you could use.
What is the workaround you have in mind? I have this scenario as well. I have a custom shaped hole, but I would like them all to be arranged symmetrically.
D'oh, in the last 4 months I have forgotten what my workaround was. I should have just said what it was at the time :-/. I believe that since Michael had mentioned rectangular holes my workaround involved doing multiple fill patterns with square holes that were adjacent to each other. What is the hole shape you need?
I had been experimenting with hexagons. Right now I am using a 1.046" x 1.796" rectangle with .179" radius in the corners. I think one way to do it is to draw a cut extrude in the center of the face, and pattern that.
Yes you can definitely do it that way.
A possible work around would be to pattern solid bodies about a phantom boundary. You can then do a subtraction of the solid bodies.
Just a thought.
The fill pattern works just fine for patterning a manually-created seed cut. The workaround I mentioned to the OP was because he wanted the pattern to automatically be arranged symmetrically within the boundary, and he didn't want to have to figure out where one of the features should go when making the seed cut. He specifically wanted to avoid manually locating the seed feature.
