I set up a simple constrained linkage, notionally a crankshaft throw and a connecting rod as per the picture, tab through and enter 10° in the delta Z rotation box of the inspector bar, the throw rotates and the conrod follows as they should, once or repeatedly. Recording the tab and entry sequence and replaying them should animate the linkage, but when I've tried with macro recorder, it crashes TC. Transform tools don't work with constrained entities, so transform recorder isn't a possibility either. I've tried this in V17 32-bit, V21 and 2015 64-bit with that outcome. Put an angular variable between crank throw and cylinder centre line and the angle dimension will drive the linkage. They can also be set between connecting rod and centre line, or conrod and crank throw, but they have angular limits that overconstrain the linkage, only crank throw and cylinder c/l have 0-360° range. Making a variable dynamic would animate the linkage. Does anyone know if that's possible? If so, how to? Can a time-based formula be used?
Works for me,Murray > no crash.
Here's what I did. in 2017
start MR click the arrow in the delta rot z 10 times hit enter. I continued the sequence then stopped MR and played back the script. Typing a value rather than clicking the arrow also works.
Are you working in GDI mode?
That being said,The MR as well as constraints always need to be 'Happy" if they're not,well they will let you know.
