Please add a grouping feature to your laserbox software that allows you to treat different shapes as a single shape.
Have you tried the Union tool?
Please check at this link https://makeblock.yuque.com/docs/share/9236bb15-e62e-4d60-9f1b-7d195428b25e?# and search for Union
If you use the Union function, the overlapping part will disappear.
The Grouping function can be treated as a single figure without eliminating the overlapping parts.
I just forwarded your suggestion to our R&D team, and was told that they will evaluate the demand for this function in the next version
