Multiple Square Pipe

The script I am working on, is an attempt to create pipework (converting lines to pipework) that is square and utilizes a rail sweep. This Grasshopper definition creates a multiple pipe with a rectangular section from curves, lines, and lines with fillet. Square Pipes.ghx is the definition

-creates a vector between the start point and a point very close to it

-creates a rectangular section normal to the vector at the start point of the line or reference curve

-creates a sweep 1 rail along the line or curve

The warning that I receive under Swp1 is: Insufficient section curves could be constructed. The image is attached, but any help that can be offered is greatly appreciated.

The sweep component David has provided in Grasshopper works for typical scenarios, but if you're sweeping non-planar curves, it needs more assistance with directionality.

I had the same warning message when I feed a helix into your definition.

So, here's some choices:
1. Add more section curves oriented on your sweep rail.
2. Program a more advanced sweep component either using a custom component or a vb.NET or c# component
3. Take advantage of someone else having already done the programming for you. My StructDrawRhino plug-in should be of use for you (if it doesn't give you the result you want, get in touch and I will give advice). One single component should sweep your profile from a parametric property table. I've attached an image, it can be downloaded from http://www.geometrygym.com/downloads Shortly I'll be adding the ability to generate profile properties from within Grasshopper (but many standard profile libraries are available such as HSS)

Cheers,

Jon

well I tried downloading and installing your plugin for version 0.6.0059 of Grasshopper, but I get this error message:

Just having a bad run of luck with the program tonight :/ Thanks again for your help Jon, I appreciate it.

Best,

One thing you need to do with Grasshopper 0.6.0059 is start Grasshopper, go back to Rhino, run the rhino command grasshopperdevelopersettings and untick the COFF loading option (this is generally resolved for GH0.7.00xx although it seems 64 bit computers need this too). You need to restart Rhino for this to take effect.

Also, please make sure you download the installer with GH0.6.0059 at the end, version 7 plug-ins are not compatible with version 0.6. Studying your screen shot, I think you have installed the GHv0.7 version. If you still have problems, let me know and I will assist.
