This video covers some of the attributes of surfaces that Dynamo can automatically report, as well as covering the topic of surface parameters, which specify a point on a surface expressed in terms of U and V. Along the way, it covers the topic of list lacing, which looks at how Dynamo matches multiple lists of data provided to a node's inputs.
- [Instructor] Now, let' take a look at…what kind of analysis we can preform on surfaces.…We'll begin with two easy pieces of information…that we can get from surfaces,…the perimeter and the area.…Let's begin by turning the preview on…for this surface node on our canvas.…We can find the perimeter in area nodes in the…Geometry, Surfaces, Surface portion of the Node Library.…
I'll drop one of each onto our workspace,…and then I'll connect our surface into each one.…Excellent.…So, with a single node each, we're automatically…reporting the perimeter and the area of our surface.…If we scroll up in the Node Library a little bit,…we can also easily extract the surface's Perimeter Curves.…
As you can see from our node preview,…we've extracted a list of four curves…that make up this surface's perimeter.…And of course, those four curves…also appear in the background 3D Geometry preview.…Now, you might have noticed that the node…right below Perimeter Curves in the library…is called Point at Parameter, which is…the same function we used in the last video…
