Hi Guys
I am still learning Lightburn but I ran into something that I can not do. Attached is a screenshot. I want to engrave inside the Blue circle up to the Red circle then I want to cut out Red circle. Please help me.
Thank You
Make red and blue the same color. Set your cut to FILL.
Select both inside and outside circles. Press Ctrl+B to open boolean tools. Select WELD (iirc). Press OK.
Ctrl+Z goes back one step. That is my most often used command 
Duplicate the red circle and set the duplicate to blue layer. Set blue layer to fill and red layer to line. Make sure blue layer is above red layer in the cuts/layers window.

Hi Thank you for the info. Attached is a screen shot if the actual part. I want to
cut the Black and red layer and fill engrave the inside of the Green layer.
Same process as the circle. Duplicate all of the red layer and set the duplicate to green. Make green layer fill, red and black layers line. Layer order should be green, red, black. That will perform the fill first, then cut the inner (red) shapes and finally cut the black outline.

The messsge says you have a whole lot of open shapes. Open shapes cannot be filled. You must close them first.
There are not 336 visible shapes in your drawing. That means you have a lot of duplicates. Open shapes and duplicates suggests you built this with a CAD program. Try building it using just Lightburn.
Everything works until i duplicate the inside sluts.
Is this what you are after? Blue engrave, red cut all the way out and the outside shape cut out?
Excuse the crude rendering, I took a screen shot from your post rather than re-created the shape manually. The red would be a line, rather than fill - I temporarily set it to fill to make it easier to visualize.
Yes thats what I want
Go back to your CAD program. Save the file as a .jpeg. import the jpeg and TRACE to get a simple SVG object. UNGROUP the object. Select parts and assign to layers. Set layers to your desired outcome .
Trace will give you an inside line and an outside one (both sides of the line). It is usually the outer line that you want to keep, but use the Measure Tool to make sure. Once you do a few, it gets real easy.
You might try this First Try center line finder. It does pretty good and was created by a Lightburn (@NicholasL ) team member (I hope I picked the right one 
).

This file must be right on because it fits into something. So my question is will it be the exact size if I save it as a .jpeg file?
jpeg is not what you want if you want to do cutouts.
I was away for the weekend and didn’t have access to Lightburn. If you upload the file here I will look at it and try to take care of the duplicates and also teach you how for future files.
Attached is the file. Please teach me how to do that.
Relay Template REV 1.0.DXF (95.4 KB)
Here is the fixed Lightburn file.
Relay Closed.lbrn2 (42.5 KB)
Here is how I did it.
Import the dxf flie. Go to Edit Menu> Select Open Shapes. Go to Edit Menu> Auto Join Selected Shapes. Select all the outline shapes and set to blue layer. Hide the blue layer. Select all the slot cutouts and set to red layer. (EDIT: I left out Duplicate the red layer. END EDIT) Right click over selected shapes and set to blue layer. Show blue layer and set to fill. Move black layer to the bottom so it cuts last.

From what I understand .dxf files are a whole bunch of segments that touch each other but are not closed shapes. You need to make them join in order to fill the shapes. There might be a way to do this on import to Lightburn or export from your CAD program, I don’t know. I do all my design work in Lightburn.

Perhaps increasing the DXF Auto Close Tolerance value will help:
I vaguely recall somebody having trouble when a larger setting enthusiastically mashed All The Lines together, so some tweakage may be in order.

That worked for me. I was set at 0.00 and increased it to 0.01. Reimported his file and all shapes were closed.
But like I said, I don’t use dxf files. This should help the OP though.
