How to make a pattern pitch grow
How to make a pattern pitch grow
(OP)
I'm guessing this isn't going to be possible...
I'm using a triangle pattern within a boundary, and I need for the pitch
to increase with each instance. So the pitch needs to grow from the center
of the pattern outwards. I work with rubber molds, and the reason for this is
to accommodate matching up to a hot mold that has thermal expansion. For instance,
the pitch may be a static 1" when it's cold, but 1"x% when it's hot.The % growth is
based on the distance from the instance to the center of pattern. Hopefully that
makes sense.

thanks!

Please Check with Pattern Increment Option in pattern feature.

doesn't do anything for incrementing the pitch.

RE: How to make a pattern pitch grow
1) Use Spacing Option with Count & pitch and now select Pattern Increment,
2) Select Direction offset and add to list and specify Increment value as you required or give Expression.
Check attached image for more understanding.
Thankyou.

RE: How to make a pattern pitch grow
Thanks, but this is a boundary fill pattern. With a boundary fill, I can pick "triangle" layout, which works really nice for a static pitch. You don't get the option to increment spacing as you do with a standard linear pattern (that you have shown).
See the attachment for my dialog.

My tool isn't the one getting hot, it just has to mate to the hot mold. So when the mold is cold, it would have a simple pattern. But when it's hot, the holes all spread apart from center (~.0015/"). So my tool's pattern needs to accommodate that expansion.
Thanks to you both for the efforts!
RE: How to make a pattern pitch grow
I was over thinking this. All I needed was for the pitch to be (i.e.) 1"x% of the original static pitch. This will make each row grow from center as desired.
