How do I use surface points in grasshopper?

Surface Divide

1. To start, in Rhino, you draw 2 curves to be lofted (in Grasshopper) into a surface.
2. In order to define the distances between the surfaces, we need to extract the same number of points on both surfaces and connect them to one another.

How do you make a polyline into a surface?

Start by checking the polylines to make sure they are elevated. Open the AutoCAD Properties palette, select a polyline, and note that the elevation of that polyline is not 0.00. If you have polylines without elevations, they must be modified to the correct elevation before placing them into your surface.

How to create a surface from a point?

I need a surface and then to create some profiles of that surface, but I can find no intelligable information how to proceed. At the moment the only way I can see to do the profiles would be to draw a 3d polyline from point to point and then rotate it through 90 degrees!

How are the values of a surface determined?

The values at the infinite number of points across the surface are derived from a limited set of sample values. These may be based on direct measurement, such as height values for an elevation surface, or temperature values for a temperature surface; between these measured locations, values are assigned to the surface by interpolation.
