Create a volume encapsulates all the ray lines

Grasshopper

Hi, I’m completely new to Rhino and Grasshopper, I use Solidworks for work and need to work with rays, but it is extremely slow. I need then to convert all the rays (straight lines) to a minimum volume that encapsulate all these rays. This way the file size would reduce and when I export them back to step files. I was hoping that grasshopper can do that. I was looking at dendro curve to volume but it doesn’t work. Can anyone show me in the right direction?

Hello
for sure it is not that simple
I advise you to put a Geometry component
Then rick click on the component and select

Then go on Rhino

Select the curve, then Enter

And it will work.

It is a good example of how Grasshopper is not easy for people at the beginning, related to this dicussion

Your lines are in a block so these are the steps I used:

  • In R8 (too bad), select the block of lines and go to ‘Edit | Blocks | Explode Block’
  • In Grasshopper, place a Crv param on the canvas
  • Select all the lines, right-click the Crv param and choose ‘Set Multiple Curves’

At that point, you have the lines in GH and can do things with them.
