Any idea why the GFUI would choose to engrave over the flame part of this shape instead of around it? I can’t find any open nodes in it…the chalice part comes out fine.

Here’s how it engraves: (ignore the blotches – I tried sticking gold foil on it at the last minute and didn’t adjust for material height. )
The SVG above shows the compound path filled with black – my test to make sure the subtraction worked. I’ve inspected the nodes and can’t find any problem with it, but GFUI just engraves right over the flame like it’s not there.
I cannot test it since I am doing a long project.
I took your post, un-grouped it, and just reversed subpath on the top entity.
Dunno if that will fix it, but works fine with lettering that does not want to cooperate. geek.zip (1.2 KB)
Had to re-save it as a SVG before I could ungroup things. Not sure why that was needed but it was.
It is easy in Corel.
I looked at Inkscape and I think the options below will do the same thing.
Select graphic. edit: Un-group all.
Select Edit Paths (F2)
Touch one of the nodes in the top (flame?) path sequence. I chose the lower node.
Key SHIFT+R
It should show a path switch in the graphic.
When saved (I think) it will be the same as reverse subpath for Corel.
If not I can explore some more, but this looks like the Inkscape method.
This is useful when you have a letter like B (with some fonts or other graphics you wish to not engrave) that will not show a hallow inside the B. Reverse the subpaths on the inside nodes and good to go.
LOL, well I guess it could be but in this case, it was my poor attempt to explain the topography of the elements of the drawing. See the flame was totally enclosed by the circle but the chalice was open to the outside when you zoomed in enough.
