In search of help with CNC design

Hi there! I am just now getting back into designing on carbide 3D - I am working on a design currently and running into some issues they are listed below

  • I am unable to figure out how to merge nodes - ie I have a design that I edited and all the lines are touching and I am not able to get them to merge into 1 image part of the lines and still pink

  • I also am trying to take this design and separate it into two like a yin yang pattern I try to use the boolean tool but I think since the vectors aren’t all connected I can’t get it to split into the yin and symbol

Hope this makes and any help is greatly appreciated! Attached is the file for reference!

Thanks!

You can’t “Join” an intersection that ends in the middle of a curve. Only a single contiguous curve.

You can cut open vectors with a contour path. If you are engraving these lines they don’t have to be joined.

To separate them, select all the curves & make a copy off to the side. Use the Trim curve tool to erase the segments that cross the dividing line.

I believe that in order for you to split this into the yin sign, you have to look at each individual picture section like a small part of the whole picture. Take the snake for instance, you have the snake cutting through different segments of the design. In order to for you to make the snake whole, you have to cut it up into segments where it intersects the other parts of the design. Take the snake coming under the arms of the women, you have to add a polyline to the two nodes that come up to the women’s arms. At this point you have closed the loop of the design and now can join nodes.

Then you would zoom in really close to that area and do node editing to add more nodes and adjust the line for the snake up as close to the line of the arm so that it looks like the snake is joined to the arm when zoomed back out to normal viewing. You will have to do the same thing along every part that you have a broke line on the design. Plus, if you want to break the design like a Yin Yang, you will have to go along the middle swoop line and create a break through each section that line cuts through.

Does this make sense? If not ask some more and I will try to explain it to you better or in more detail.

I had a design I made about a year ago that was very detailed and had a ton of vectors in it. I had to define each little vector in order to get my program to understand it and define toolpaths better. It took me 3 days of editing in order to get it right, and in the end the client and I were both pleased with it.

Another issue that I think you will be seeing is when you try to split for the Yin Yang. When you flip the one half of the design to it’s correct Yin direction, your design will become all messed up. Nothing will line up as it does now. If you are hoping that you can split the two ladies and flip them to make the Yin Yang and the two ladies are on opposite sides of each other, that will not work. You would want to focus on a pivotal point where the two ladies are in their own section with only a small point of contact between the two of them, such as connecting at the hands coming together. Make sure the hands are at the central pivoting point so when you can flip them, they both come together at the hands. Just something for you to think about.

This is a family-friendly forum, and your design pushes on that boundary, hence my editing your post to blur the link and making the editorial comment above.

This sort of thing is discussed in various links at:
