How do I merge two drawings together?

I have 2 object, a dog foot print from an image that I traced and resized for my purpose. I drew a rectangle and I want to join the two together as shown in the picture below. My issue is that I don’t know how to delete the top horizontal line from the rectangle and just the bottom outline of the footprint to make it one piece?

I hope i explained this correctly. Thoughts?

Both objects need to be converted to path. Select the rectangle, right click, convert to path.

Then use node edit (Tools->Edit Nodes). Edit the rectangle first, select the top line and type ‘t’, it will trim the line to the pad of the paw. Then do the same for the other two horizontal portions of that line.

Now select the bottom of the footprint. Press ‘t’. It will disappear and you’ll have what you want.

Thank you Tom. That worked for the rectangle but when selecting the outline of the footprint, “convert to path” is greyed out. I will attach the file for your review.

That’s because it’s already a path. “Convert to Path” is only needed to convert “primitives” in LightBurn to editable objects.

In your case, there’s a much simpler way to do this: ‘Weld’. The Weld feature takes the outline of multiple shapes and fuses them together into a single shape covered by the originals - It’s kind of like if you and someone else stand near each other on a sunny day, and your shadows overlap - If you just traced the outline of the whole shadow from both of you, that’s kind of what weld does. (Boolean Union works almost exactly the same too).

Select JUST the outer line of the paw, and the rectangle beneath it, and hit the Weld button on the toolbar (just under the Offset tool)


It was already a path so you didn’t need to convert it. However, since it was created by some tool that doesn’t know what a curve is, there are literally thousands of nodes in it. I broke it up and rejoined the way you want it, but the upper portion is still lots of tiny vectors. I forget how to clean this up in LB but it’s usable the way it is.
Also, I don’t have 1.0.05 installed, so I saved it with 1.0.04. It should be ok.

Ah, yeah, I didn’t suggest weld because I thought that all the elements in the paw was one object…
Good thing we have you around to keep us on track :slightly_smiling_face:

There are a lot of nodes in that source file. :slight_smile:

Look to ‘Edit’→’Optimize Selected Shapes’

Optimize Selected Shapes

Attempts to fit the selected shapes to arcs and lines within a specified error tolerance. Useful for reducing the point count in a shape, or recovering arcs from software that exports them as many small line segments. - Redirecting...

I did try “weld” but that either cut off the bottom of the paw print or the rectangle disappeared. I redid the steps Tom suggested and it worked. Seems you have to select the object, then edit nodes, then select the area to be removed, then select “T”. I was hitting “T”, then selecting the area to be removed. It didn’t work that way!

I created the paw print by importing the png file, right click — trace— then moved the trace over and deleted the originator png. I guess I just assumed it was a solid line after that.

Thank you for your help.

OK I made 3 of these just to get this down. One worked, the other 2 do not. I was able to remove the horizontal line from the rectangle on all three. I was able to remove just the bottom portion of the paw print on ONE of the three examples but the other 2 will not accept a “weld” or a “edit node”. It will either deleted the rectangle (weld) or delete the complete outer paw shape (edit node).

Hmmmmm !!!

When you do the weld operation make sure you are selecting only the outer outline of the paw and the rectangle. Make sure the inner portions of the paw are not selected. Ungroup if required.
