Beam along lines (14.2 KB)

I created in grasshopper a beam cross section. I like to sweep the beam along lines, which i also created in grasshopper. How can i achieve these?

Since you want several profiles to be swept along several lines this requires a level-2 datatree, I used Graft Parallel from Elefront plugin.
From a geomety standpoint, you need to Orient the section in a perpendicular frame - aligned vertically here - and then use Sweep1.
It could be simplified with an extrusion, but would only work for lines. (22.6 KB)

Thanks, when i open your grasshopper definition i get an error at sweep 1. What am I doing wrong? (15.6 KB)

Booo ! Region Union is cheating :smiley:
(Assuming here that the OP wants three distinct plates and not one solid)

You need to download Elefront 4.2.2. When opening the file it should ask you to do so, or you can use PackageManager.

Have a look at @Joseph_Oster solution which avoids that but only outputs one solid per beam, maybe it’s enough for you.

You are ignoring this error message when you open his file:


Me too. I guess there is problem in @magicteddy 's definition.

Tahnks, it works! To create solids i use the cap holes component.

Even if @CeliaNE wants three distinct plates (which doesn’t seem likely), it can be done without Elefront, like this: :sunglasses: (19.4 KB)

How can i sweep the beam under the curve? At the moment the beam is upwards the curve.

You can move the RUnion output in the -Y direction, like this: (16.3 KB)

Or construct it differently, Or move the reference plane (default is XY). Or… whatever. The most important thing is to understand the code so you can modify it.
