rotation of parts
rotation of parts
(OP)
I have created and assembled various parts for a rotary system. On one end I have a part that can be rotated, and is connected by a shaft to another part. I can rotate one part, but the other parts do not rotate with it. While the parts have various assemlby relationships, I can't figure out how to create a rotational relationship, whereby rotating one part causes the other parts to rotate. Any guidance or tips welcome!

The shaft is added to Grounded Parts, the other to Moving Parts.
You will then need a Revolute joint between part and shaft.
Then in the joint properties Set the Motion Type to Displacement. (RMB on the joint > Properties)
Set the Function to Step.
Initial value 0
Final Value 90° (or whatever angle you want)
You can also set start and end time but leave those at 0 & 1 sec for now.
Click the green tick to apply the changes.
Now click simulate.
The part should rotate around the shaft.

Where would we be without sat-nav?

I always say No and then define my own joints.
Is the part that isn't grounded in the list of moving parts?
Are there any joints in the list of joints?
If so you should be able to right click and then select Properties as I described.
You should also be able to see the joint on screen.
A revolute joint looks just like a hinge.
Please supply a screen shot then we can see what you have.

Using these parameters the animation still goes from 0 to 75 in 1 step. I want it to go 5 degrees in each step. Am I going about this the right way?

Frame Time
Start 1 0
End 15 3
Step 1 0.3
Yet when I click Simulate, the simulation goes through all 15 frames, but the animation goes from start to finish in just 1 frame. In the Simulation tab I have Duration 3, Number of Frames 15. Is this a bug, or am I missing something here? Any insights welcome!

Instead just use the gear assembly relationships along with a motor(s) to drive the assembly through its range of motion.
The motors have the ability to contstrain their movement to a specific angle or distance if that is necessary.
This workflow is far easier and much more flexible.
You have the ability to simulate just the motors in the regualr assembly environment.... or move into ERA and combine them with other animation techniques.
Hope that helps

To restrict the movement to a certain direction or angle the easiest way is to not use the motion environment at all.
Instead place motors on the parts that need to be moved. This is done in the regular assembly environment. Also you can create gear relationships between other parts if they need to move as a result of the parts already being moved by the motors.
