I'm running 3.4.5 on Slackware Linux. I've been hesitant to upgrade seriously because everything works right now, including some stuff that was difficult to get to work. Also, my only connection is via a phone, so I try to avoid big downloads. I think my problem is a bug in that version. I started a...

Regardless of all of those factors you mention, with all other entities being equidistant, and making a circle...

I'm not making the same sprocket... I'm making a considerably larger one. The process should be the same, however. The one I'm making is large enough that we'll have to cut it in halves on a 5'x10' plasma table. I actually got my outside diameter from a table somewhere, and am managing to avoid the ...

I'm trying to use the procedure outlined in this video: https://youtu.be/-4YYwKHctnk?si=D5jeHjjydgQZvTzo The author uses the intersection point of a circle with three tangents to create the larger circle describing the tooth above the pitch line using a function called TAN TAN TAN. These are the ora...

I can't s...

I am curious what the advantage of doing this with software might be. I tried to make a quick drawing of something I had rattling around in my head (a pretty easy part)....
