Imposed motion Cartesian Coordinates

[Anonymous]

I am working on a model that has nodes orbiting a central point. I need to be able to import a list of X,Y,Z coordinates for each node with respect to time. I have used imposed motion through joints before to do something similar however nothing exactly like this before. 

I thought there was a way to put each section (x,y or z) of the coordinate list into each constraint/joint and having a spline be generated off of those points. I know how to do it for rotation but these are linear relationships and I am out of my element.

If worst comes to worst I can manually input each coordinate value into a spline on a sketch and use a line, pushed by time, with the length of the distance under the spline. That would work too but it is not an ideal system.

Any help would be appreciated

Hi! I am not aware of Imposed Motion. Is this about Inventor or Fusion? This is Inventor forum.

Many thanks!

Inventor has it. You can add a coordinate list into a joint. The program will generate an interpolated spline and then use that plot as a way to vary the position and angle of joints.
