This video covers a few attributes of curves that can be queried using Dynamo, as well as covering the topic of curve parameters, which specifies a point along a curve expressed as a decimal number between 0 which represents the Curve's start point, and 1—the Curve's end point.
- [Instructor] In the next two videos,…we're going to explore some of the methods that we can use…to extract information about curves and surfaces.…For this example, we begin the exercise with two lines…with each line created by connecting a start point…and an end point.…We also have a surface that was created…by lofting those two lines together.…Let's begin by analyzing one of those two line objects.…So for the moment,…I'm going to turn off the geometry preview on this surface.…
If we navigate to the geometry, curves,…line section of the node library,…we can see that there aren't too many options…in the query section for us to analyze things about lines.…That's because a line is a specific data type…that falls under the larger category of curves.…Instead, let's head over to geometry, curves,…curve within the node library.…Here we can see we definitely have more options…to choose from.…
For example, we can find things like a curve's start point,…end point,…and length just to name a few.…Now these nodes can be applied to any type of curve…
