Taper pipe command

Dear Grasshopper member,

I have been using the pipe tool to pipe a mesh created from a surface using the demonstration in the Grasshopper Primer Manual p.84 so to create a tubular structure to a tower, this has worked well. However I would ideally like to taper this pipe so that the radius of the circle is different at both ends of the pipe thus all the pipes gradually reducing in size the higher they go.

There are similar discussions on the forum using the sweep1 command for a curve but have not had much luck making this work either.

Can you help?

Tom

I got this file from a older discussion. Maybe it helps?

Best regards

Hi Dedackel

sounds great, however i'm unable to save the ghx file it just opens a page of scrips. Please can you assist me in what procedure i need to go through?

Thanks

Tom

you can try using another browser or a download manager

It's hit or miss sometimes as to whether you can simply click on a link and it downloads or opens an XML HTML page. So the safest way is to Right Click on the link and save as.

Hi Dedackel

sorry to be a pain! It works well on a flat surface but doesn't naturally apply itself to a lofted surface (see attached). i need the pipes to reduce in diameter the higher they get, Also i didn't explain that the mesh needs to be faceted like on my baked image attached.

Much appreciated

Tom

I do not have rhino here. I can have a look at it tomorrow morning!

Hi Tom, I made a solution for your diagrid tower, based on the curves of the primer page 84 curves. If that is also what your mesh is based on (or somethin similar), this will work nicely.
