Ok, so far, this has to be the most difficult drawing i have done. I mean, i have modeled some crazy stuff like engines, steam engines, aircraft parts, 3d printer parts etc, but this gear box face plate is driving me NUTS!!!
The reason it is so difficult is because there are a lot of radius’s that i need to draw into the face p[late so that when it is milled, or machined, its not alot of sharp corners. Here is a pic of the actual gear box i made with a manual lather and manual mill. FYI, manual stuff is scary at times haha.
Ok, with the attached photo of my sketchup pro piece, you can see that i did ok with the cut outs, but they are NOT accurate at all.
My question is, see the lines circled in blue? anyway to just select those 2 lines, hit arc and have it draw an automatic tangent arc with a specific radii? In other software i have used, thats how i would accomplish this, but this is the first time i have had to use the arc tool to make accurate cuts. There are alot of places, since circles in SU are segments, that it is “tangent” but still not accurate, if that makes sense. Oh, and i will make sure its just a flat drawing when i do this. I push pulled for just kicks and giggles to get an idea of what it looks like
I could do the math, but its time consuming
