Wheels on curved rail
Wheels on curved rail
(OP)
Hi,
I am trying to make an assembly with a set of wheels that can be rolled (or moved) along a section of curved rail.
I need to be able to roll the wheels back and forth for demonstration.
It is possible to do this? I have tried various relationships but have not been able to get this to behave properly.
Here is a an image of what I am trying to do....

The wheel on the outside rail needs to be joined so it will roll along the curve.
Thanks.

I need a pin to follow an "open" rail, which is made of many curved planes. The CAM function requires a closed surface in order to work. I've tried to "close" it, but wasn't able.
The only thing that almost worked was the TANGENT function. But since it allows just single curves, the pin won't follow the whole curve, but single pieces of it.
Has someone found a way to make a body follow open curves?
Cheers!

I too was getting the message that the loop has to be closed to work.
Patrick, was your example similar to what I was doing in the link above? I would love to hear how you got it to work as this is something I need to do often.

Can you create a construction surface that would be kind of a guiding wheel rotating perpendicularly from your existing wheel (just like a roller coaster) then you would be able to use the cam relationship in that plane to control the position of your wheels.
