Snipping lines of a border and circle intersection

[Alphonse (Alan H.)]

How do I snip and delete the highlighted lines out of this example. These green lines are a border around a nameplate and the circle is intended to be drilled after lasering for a screw hole to attach the plate to some machinery.

I drew the border then put in a circle. I used the offset shapes tool to get wider lines via “Offset Fill” for the burn. I would like to eliminate the highlighted lines of the border in the attached snippet

This might be a boolean (Union, weld or subtract) depending on the two internal lines and if they’re part of a closed path.

If you’re willing to share the file feel free to post it here.

If you’d prefer to explore the boolean tools this is handy:

Thanks John, I tried the Boolean tools with out success.

I am attaching the file plus a photo of a card burned with the file.

1. group both shapes that makeup the green outline of the card
2. select grouped green outline, add outside circle to selection; then Tools->Boolean Union
3. Profit

Repeat for other side.

Note that I’m somewhat interpreting what you’re asking for.

If you want literally what you asked then for step 2, add the inner circle instead of the outer circle.

I selected the outer two lines and Grouped them. I selected the Grouped perimeter lines and the Outer circle. The line form (the style of the dots) is different when a Group is selected. Note that the dashes are different on the outer circle than on the perimeter. I was shown this helpful detail not that long ago.

Then I did Weld Shapes on the outer circle which did nothing to the inner circle.

It’s not exactly what you asked for because I got rid of the short perimeter lines between the circles.

Thanks @JohnJohn, that is exactly what I was looking for.

Now to replicate what you did. A little “learning by doing”!

Thanks again for the help.
