I think I just learned something new from you too. This whole time I was wishing there was an easier way to take the difference of multiple objects, rather than selecting them all individually. Thanks!
@mforrester1962 I pretty much did the same thing @Jules did in Inkscape. I ungrouped the entire thing, clicked the stripes (individually unfortunately, going to be trying out jule’s tip now too) and than main rectangle and took the difference. After I did that for all the stripes, I clicked your gray area and hit union.
I left your engraved section off to the side, but before doing the union, you would probably like to center the engrave part over it for perfect alignment, then click the gray spot and union it to the main rectangle.
I’m attaching the SVG I played with. I made a duplicate copy underneath without unioning the gray part, so you can see how I aligned it first, then click the gray part and union it with the rest of the flag.
