Currently a cell can be placed by it's origin, however once placed it is fixed in it's location, and the origin point is not able to be updated with constraints. It would be great if we could constrain the origin to another element or apply parameters to the origin xyz values so that the cell location can be updated parametrically
The following Constraints tools recognise vertices.
2d Constraints: Coincident, Fixed, Concentric, Dimensional.
3d Constraints: Coincident, Fixed, Concentric, Dimensional, 3d Angle.
They should also recognise Cell insertion points.

I also need similar functionality for some design automation. I can build functional components (parametric cells) for individual pieces of a collection of assemblies, but a single functional component for all the different options is too complex.
With graphic cells, I can use association to make the cell origin constrained to a keypoint of a line, or centre of circle, intersection of two lines, etc. This allowed me to break a very complex problem into smaller parametric pieces. Unfortunately, the inability to use association with parametric cells is making things difficult.
if i click parametric cell origin point to be coincident with some other point it does not move?
