Please provide a detailed description of the issue.
I am a new—and still somewhat unsure—user of Shapr3D. I have managed to learn how to create the simple models I need—specifically, basic selector rulers for my knitting machines. Now, however, I need to print a cast-on comb for one of my knitting machines. I am able to model the ruler itself, but I don’t know how to create the small holes required within each of the ruler’s pins—specifically, the holes that need to be positioned on the _inner_ side of each pin. Is it possible to design a single pin and then simply copy or duplicate it the required number of times? Please forgive me if I am not phrasing my questions correctly; I am not a technical expert, and I apologize for any confusion. I would be very grateful for your patience in explaining this to me, or for a link to any relevant tutorial materials. Thank you.

If I understand correctly, you want the holes of the needle to be displayed on the model?
You draw a circle with the appropriate diameter on one of the protruding parts and then you can extract it all the way. Or you can even draw it as a separate body and then extract it from the things. I’ll send you a quick video.

Is that what you thought?
