Make pattern failed in diagonal line

Hello everyone, I got a trouble when try to create herringbone pattern using Make pattern

The hatch was created by Make pattern didn’t smooth. As you can see in the picture below, the pattern is on the right hand side.

I think this is a bug, because when I rotated my drawings 45 degree and created pattern again then rotated the pattern 45 degree too, it became normal

Thank you for reading my topic. I hope pyRevit can fix it on next release

this is my picture after rotate 45 degree
