I get an extra G0 move when it crosses the curve seam: I am cutting TPO with a tangential wheel cutter.Ĭ is the rotary axis that keeps the wheel tangent to the cut. If I get an open curve, then it’s messed up all the way through and I have to keep battling with it. When I can offset to the outside and get a closed curve with Loose=No then everything is fine from then on. So I have a quick way to verify things in Rhino, just try to offset to the outside… but I have no idea how I can fix it. The problem is, I don’t know they are a problem until I get out on my machine and get an error… then I have to go back to my office and figure it out, fix it, re-generate everything, etc… it’s a major slowdown in my workflow, it would be much better if I could fix this in Rhino when I try to do the offset and see it gets offset into a microscopic open curve. I can fix it in my CAM program by re-filleting them, but why can’t I fix them in Rhino? The Offset is only an indicator that there is something wrong and I notice the same thing wrong when my CAM programs goes to offset for the toolpath. The offset I just use for positioning these, it’s temporary, but I have noticed when I have this offset problem, I also have problems in my CAM program… so I am trying to figure out what is going on and how to clean this up so when I get to the CAM program I don’t have to figure anything out, I can just get it done. I can turn on Loose=Yes and then I get the offset, but that is not resolving my problem. Side to offset ( Distance=1 Loose=No Corner=None ThroughPoint Trim=Yes Tolerance=0.001 BothSides InCPlane=Yes Cap=None OutputLayer=Current ) If I have a closed curve with G1 Continuity, then why can’t I offset it to the outside and get another closed curve with G1 Continuity? or if I analyze each pair of entities with _Gcon it reports each pair are all G1… soooo? I just can’t understand what’s happening here. Can anyone figure out what is wrong with my geometry and tell me how I can detect the problem and fix it? I have verified that I have G1 Continuity with two methods, if I explode it, and try to select it with SelChain and set ChainContinuity=Tangency then no matter where I start the selection, the entire filleted triangle is selected. I don’t understand this at all, when I joined everything it says it created a closed curve, and I should be able to offset any closed curve to another closed curve, why is this one resulting in an open curve? I can see the tiny segment it makes:īut I can’t figure out how to fix it… I’ve deleted the fillet and re-drew it… I’ve deleted the line and drew a new line tangent to the two curves.

But when I click on the side I want to offset to, it just disappears and it says

Sure cuts a lot 2 offset
