Simple pendant engrave error

I got excited there. I tried fill and no stroke for the two circles and it still failed. This is what it should look like:

Unfortunately, there is a known issue with how the GF interprets CorelDraw created SVG files that deals with the winding rules…the current work around is to either save the file as a PDF or rasterize the results of your vector drawing before saving the SVG file.

Another thing to take into account is that the white filled area in the center has to be subtracted from the blue filled area…the GFUI treats any vector fill color, even white fill, as something to be engraved.

There’s another mini-tutorial for dealing with vectors that explains it here:

Actually, at 600 ppi, the Glowforge handles raster engraves just as well as vector engraves, and you get more options for it…I tend to just recommend rasterizing the engrave portion of the design these days…it tends to be quicker.

Sometimes :slightly_smiling_face: 95% of the time it appears to choose the method the GF handles. It’s the other 5% that’s problematic.

It likely has something to do with the order the objects are drawn or whether the Boolean operation is foreground minus background object or vice versa. I never bothered to test the variables as it doesn’t happen often enough to make it worth the time

Most often people forget the Boolean or don’t know to do it and just lay one shape on top of the other expecting to see a blank piece.

I didn’t realize that…I thought it happened all the time. So it’s mostly just a forgetting to subtract thing?

Well, shoot! :neutral_face:

No. It happens after you subtract. But it’s not easily replicated. It’s some obscure combination of steps that causes the fail. What’s worse is because it’s a valid SVG operation opening it in Inkscape & resaving it won’t make it safe so the GF deals with it.

But most times people blame the winding rule error for Corel files it’s because they didn’t do the subtraction in the first place :slightly_smiling_face:

I ran into the same problem using Corel. Below is how I figured out how to make Corel work for the GF.

This is how I would approach what I think you intend.

  1. The outer most shape should be filled.

  2. Make the inner monogram into a jointed filled object.

  3. Subtract / punch out the monogram from the larger shape to create a construct with a background area around the monogram to be engraved and the rest ignored.

Excellent. I remember reading that in the spring but promptly continued to draw this GS in random order :grin:

BTW, you use the Weld tool in your post. Have you tried the other booleans (simplify, subtract) and does it behave the same?

Yeah that’s a much better way to explain the problem to a Corel user…thanks for the reminder! :grinning:

Only if you cut the monogram out of the engrave shape. If you put a white circle on top of a black circle, it looks like a donut to us, but to the GF it looks like a black circle to engrave, and then a white circle to engrave on top of it. You have to actually cut the white circle out of the black circle so that it IS a donut, to get a donut from the Glowforge.

Yes, it should work the same. Just remember if you’re creating an island fill to follow the even/odd pathway before you merge the curves.

Just, please don’t divide by 0. (though this is a real place in California)

What is that? Salt dome collapse? :smile:

Well that’s a cool idea! Similar to what we do with the back yard, on a much smaller scale. (That’s one heck of a French Drain.) :sunglasses::+1:

Wow, this explanation is great. I came to the conclusion it was a Corel-centric issue. I was able to do what I wanted in Inkscape without a hitch but I know Corel so much more. I am anxious to get home and try out the righ-to-left border option with the text and see how it flies. Thanks for all the help guys!!

I’m with you on that. I use Inkscape in my classes but prefer Corel - I’m an early Corel guy so that’s the go-to app.

The issue is really with the GF. Corel is using a feature defined in the SVG spec that the GF doesn’t handle. Their implementation of SVG support is not complete. Good enough, but not everything.

Hopefully the Glowforge people see this thread (and others like it) and look into fixing the problem.

They’re aware. We found it a year or so ago and it took a lot of digging to find the cause. It’s not something that is high on the GF list because Inkscape is the recommended design software now. (They promised direct from AI but no word on that either.)
