SAP2000 Point Local Axis

For the Geometry Gym plugin users, remember that I encourage and look forward to receiving suggestions and ideas for improvements and new features to the tools.

Here's a fairly simple one that where identification of node local axis can be straight forward in Grasshopper, but not so easy to do within the Structural Analysis software.  This user wants to be able to apply a local coordinate system to the points (nodes) generated to SAP2000.

  1. Where does the first two sets of points come from?

  2. The edge curves (which are then lofted to form the surface) are taken each from a set of control points. If you right click on the point inputs, you can nominate "Set Multiple Points" and I used each elevation view in Rhino to set them in plane.
