Fill Pattern where the shape of the body to be patterned is different each direction

BStump

I am looking to see if there is a fill pattern in Featurescript that has the ability to control both direction dimensions independently.  I have a fill where the shape of the body to be patterned is different each direction, so to pattern it I need to control both directions.  Anyone done this or suggestions?

I'd suggest copying the FeatureScript Fill Pattern, adding a parameter named definition.length2 and making the following changes:

Change line 70 to

var maximumIndex = round((norm(diagonal) - (definition.border * 2)) / min(definition.distance, definition.distance2));

and change line 90 to

var translation = (direction * i)  * definition.distance + (angled * j)) * definition.distance2;

If you want the two directions to be perpendicular (rather than the current hex grid), you'll also want to change line 45 to use 90 degree angles.

Cheers to @NeilCooke for writing clean code that's this easy to modify
Let us know if you encounter any issues!

Well that is a good start. In this case you need to consider the shapes I want to pattern to be something like dog bones (https://macrotrac.com/wp-content/uploads/2016/12/i-trac-pic.png ). I just need to be able to do a fill using the basic shape with appropriate offsets in each direction ( I don't need the surface details, the tabs, pins, locks, or tread). The shape nests, so a bounding box would show significant overlap. The angle is not 0, 45 , or 90, but about 29.56 degrees. I am seeing if I can find a way to simplify layouts using Onshape.

@kevin_o_toole_1 as much as I'd like to take credit for it, the master code comes from the master coder himself @paul_chastell
