Looking for an easier approach to cutting up a pattern

[RichM (Rich Morris)]

I’m attempting to create a checkerboard ring and looking for an easier solution than what I think I’m going to have to do to create the alternating sets of ‘squares’.

I’ve created 4 circles, each offset by 1/4" and 58 1/4" x 3/4" rectangles in a circular array which gave me the pattern I wanted. Next I want to create individual boxes, grouped into alternating sets, so I can carve the pattern. Really I need only one set, the alternate group will form naturally when the first is carved.

Does anyone have any suggestions to shortcut the process of trimming vectors on a couple hundred squares in the shape of a ring?

I’ve attached the file if anyone is inclined to get into the weeds on this one.

Thanks!

Just draw one set:

and delete what is not wanted

Then duplicate the line:

and flip it:

and drag into registration:

You’ll want to slightly double up the interior lines (I’m assuming you’ll want to do some sort of V carving to make the shapes, so will want closed regions):

and you’ll also want to replace offset geometry w/ drawn circles…

Probably the lines need to be a bit more angled — doing that can be used to set the gap:

Duplicate the line and drag into registration w/ the original:

and Join Vectors:

Then Node Edit to remove the extraneous node:

d

Done

Duplicate/Delete what is not wanted as necessary:

Adjust the interior lines:

and also make additional lines for the interior/exterior:

(remembering to double)

Select everything but the interior and exterior:

Trim Vectors:

Remove what is not wanted:

Until one arrives at:

OK

OK

Join Vectors

Yes

Use Circular Array:

m

to make the desired copies:

which then allows V-carving as expected:

Ummm, well crap… I wasn’t expecting that much help! Thanks!

Have you always been an overachiever?!

I’ll go back to playing with my banana and tire swing now.

Seriously though, thank you for all of that!

The cut I was going for was slightly different than the one you created, but I used some of your techniques to accomplish it. Ended up being much quicker and precise than my previous approach. Thank you again for all of your help with this.
