Hi all

I have a diamond pattern that fits neatly into a rectangle, I would like for this pattern to blend into an archway at the top

I accomplished the example on the right by manually adding move/copy body features

The downside to this is its an 'eyeball' technique that takes time and has to be reworked each time the width/height/pattern spacing changes.

Part of my design objectives is to be able to sit down with a customer and interactively alter the design to their wishes.  It's ok to do a lot of work up front, but when the time comes, the changes have got to be pretty quick.

I was wondering if anyone has any suggestions to improve this?

Fill Pattern seemed the logical first place to go, but I found it was not possible to specify the margins as the 'driving' dimension in the pattern.  And whilst it does a good job of clipping the boundary, it seems essentially the same as a linear pattern but with less control.

I've explored deform which looks promising if there's a way to build on it

I was thinking I could make a lot of tiny holes and then somehow pick them up. A triangle cut out would always give me a point to use with Move Body

or a similar idea with a flex feature that gets projected back onto the plane

I would need to get a surface more like this

A complicated 3d sketch solution seems my only way at present.  Can anyone suggest a better way before I disappear down a rabbit hole.
