I have a problem with a swept cut along a spiral.
Essentially I am making a 1/4-20 thread with an actual cut (I know that isn’t the common way to do it). The thread length in my model is driven with a design table. This works for all kinds of different sizes of thread and lengths….
*Except* if I make the thread 4 inches or longer the entire model disappears.
If I preview the cut for the 4 inch model it shows up just fine. The underlying rod is there, the spiral looks correct, and when you click OK there are no rebuild errors… but the entire model just disappears. Make the thread 3.75 inches and it cuts fine.
I turned down the graphics settings and it made no difference.
I also checked the model on a second computer and it seems to have the same problem.
Has anyone had similar problems? Any ideas what could cause/fix this? I can provide the file if someone wants to take a look at it.
