Grasshopper

algorithmic modeling for Rhino

Hi:

I am trying to extrude a profile curve trought a rail with a sweep.
I get it but there are some continuity problems in the grid. The profile changes sides at some points, creating steps in the grid.
Does anyone know about this problem?

Thanks

Here's the StructDrawRhino attempt at what you wish to model.  I see I still have to activate the surface normal if you want to orient the members to the surface (I'll do it in a moment).  Note also I used Kangaroo to remove duplicate lines.

 

Hope it helps, post back with any questions.

 

Cheers,  Jon

Hi Jon:
Thanks very much for the solution. I got to a similar solution using your awesome Geometry Gym tools. It saved me a lots of headaches. 

The Kangaroo tip was also very usefull.

Here I post the definition.


Cheers,

I just uploaded a new build with orient to surface normal activated.  I've attached a sample.  Glad the tools are helping.

Very usefull too, but I can't orient it perpendicular to surface.

Thanks very much for the help again!

Cheers

Sorry, I missed this post.  Can you explain further about how you need the orientation to be defined?  I can better advise how to achieve this.

Hi Jon:

 

Do you know how can I control the orient to surface normal profile. Because I'm trying to connect the surface which I want the profile to be perpendicular to,  to the input "O" and it is perpendicular when it is paralell to xy plane but no when it gets vertical.

Hi Fernando,

 

Can you post (or email a file) that demonstrates this please?

 

Thanks,

 

Jon

Hi Jon:

 

Excuse me for the delay. Here are the files that I had problems with. I finally resolved it with a sweep by two rails with regular GH components.

 

Cheers,

can you describe (printscreen image is good) the errors you see?  The version you have installed is compatible with latest grasshopper.

 

I'll check Breps shortly to check they work (and not just surfaces).

 

Thanks,

 

Jon

Hi Frank,  I went through your post again this morning, and I see what you mean about the errors.  Grasshopper has had substantial changes since this definition was created, I'll try installing the older version shortly and reposting an updated file that works.

 

Cheers,

 

Jon
