Determine Section Plane Direction to Follow Convention?

Rhino.Inside Revit

Hello,

Iam trying to cut a section at each grid line following the basic convention of looking up or to the left. I have been able to cut a section at each grid, but I dont know how to determine the correct plane from the plane of the grid to achieve the convention. It looks like it depends on which way the grid was drawn.

If someone could point me in the right direction :slight_smile:

Hey Scott, could you define a global reference point each grid should face towards? If so, graft the list move the Pt origin of each plane in axis +/-X an +/-Y an use “Sort List” to find the closest point which indicates the right direction you plane needs to be adjusted.
