I have just downloaded version 4.890 of GM and I've run into a problem when trying to generate an epicycloidic pinion when using a specific wheel/pinion combination of 32/8 teeth. Every time I try to generate a pinion from this combination the program crashes. Changes to diametric pitch value have no effect.

As far as I can tell it is only this tooth combination that causes the problem. Spur gears work properly. All other tooth combinations also work.

Hi Russ:

  Seems to work fine here. Does it do it if you turn off spokes. That pinion is small so spokes can easily intersect each other which could cause a crash.
Ive taken much greater care in the new code to eliminate crashes in such things and instead show the error or fix it.

Spokes are turned off.

Russ:

  Strange. I cant get mine to fail. Whats your point distance setting? Metric or imperial? Ill give that a shot.

Thx

Art,

I tried both metric and imperial units and various point distance settings to no avail. I finally rebooted my system and tried again. After a few unsuccessful tries I was able to get the pinion to generate. For now, all seems well. I will report if this odd behavior reappears.

thx

Russ

Thx Russ:

  There must be some intermittant coruption. I have it listed to keep watch for.
