Change Multipipe's StrutSize bulging selectively/dynamically

Hi there :slight_smile: fairly new to Rhino 3D and Grasshopper universe. I’m tweaking a script from Parametric House and am trying something with the multipipe component.

I want to have bulging at the end points but don’t want to change the diameter from the inside of the shape, where I highlighted with green. Tried some graph mapper with line distances/ point atractors. Is there a way to select exacly what parts to bulge with StrutSize?

You can use a bunch of circles to set location+radius manually

Hi @parametric_fart

NodeSize can be set per node as Riccardo shows, but StrutSize is a single global setting, so there isn’t a way to change it per strut from the component inputs.

Instead what you could do is make the outer nodes bigger. Here showing how to select the outer points:

For more strut-specific variation, you’d need to do it as a post processing step. If you feed the Multipipe result to a Mesh component you can get the control points, then you could select ones near midpoints of particular input edges and scale them etc.

Thank you! Understood it

Thanks! I’ll try that
