The files for the geometry and setup can be downloaded here: sampling_points.zip

This example will show you how to sample points of an object using the solution sampler block.

First, a point need to be placed on/in the geometry. This works with many points, but for this example, we will just sample one. The point is located on the geometry here.

It is necessary to use a point or geometry object to reference this point from Grasshopper. This can be done by right clicking and setting the point.

Now, the solution sampler object can be placed. Connect the solver output to the solution input on the solution sampler.
