Curve drawing

Grasshopper
1

Hello All,

I’m looking for an effective way to draw curves in Grasshopper.
Usually in Rhino I like to drag the control points of a curve in order to achieve the desired result and I’m trying to find a way to parametrize this process.

In the attached file there’s a simple exampl, a wheel, placed on its final position. What I did was to create a plane, which is placed on the hub of the wheel, then I moved the origin point in the two directions to create a set of points, so the curve and the revolution.

Well. Is there a better way for this? I see some tutorials with the Graph Mapper component in use, but I don’t understand if it’s aligned with my intent.

Thank you!

Point Oriented lets you define a point from its coordinates in a specific plane. This could avoid all vectors and Move.

Since you are working downwards, flipping the local axis of YZ plane allows you to define only positive numbers and avoids all expressions.

MD Slider would allow you to have more graphic control, but if you want precise dimensions, forget it.

That’s the solution. Thanks. I will explore the MD command for other application in the future.
