Capture region that geometry crosses during transformation

[dom_tweed (Dominic Tweed)]

Hello, I’m wondering if someone can point me in the right direction to capture the entire region that a simple geometry crosses as it goes through a finite rotation and transformation.

Specifically I would like to be able to have a single geometry that represents the entire region passed by the geometry in it’s full range of motion. I am including the grasshopper file that includes the full motion and a photo which is simply several baked step along that path of motion that represents what that shape should look like as those steps approach infinity.

Thanks for any help or direction you may have,

Here are a few photos for to better explain the problem:

The second screenshot shows roughly the shape of the single curve I am hoping to achieve.

Hello
I think you can elevate curve profile depending on the angle, then record positions using a data recorder then loft the curves
then project on a plane

Region union seems best.

How to create a silhouette curve?

Agreed, it’s not the ideal workflow and perhaps there’s a better method that involves a plane intersection or some kind of convex hull boundary. Perhaps there’s a method for getting an isocurve or subd demising line that someone can point to

Thank you for the solution Laurent - I am going to explore it to try and fully understand the approach!
