Subdividing problem

you need to use divide domain squared, this takes a surface and recognizes its existing domain in both U and V directions then allows you to divide it. Then use isotrim to create the subdivided surfaces.

Hey Michael, thanks a lot for answering, Im sorry my post wasn't clear enough, I already used the divide domain squared and the isotrim command, the error says:"Data conversion failed from Brep to Inverval". The wierd thing is that the loft is working just fine, I'm attaching a printscreen of my definition, you can also take a better look from the files I posted in the opening discussion.

 

Thanks in advance!

hi luis:

yes, same thing has happened over here, i'm not sure why.

this has happened to me with the loft component, specially when lofting arcs

I'm sure David has to know the reason, but here's a solution for the problem

use sweep 2 instead of loft

hope this helps

best

Check your loft surfaces.

Although it says "BRep to Interval" it should better say "Surface to Interval" in the error message. The Grasshopper Surface is stored as a BRep with only one face. Conversion will fail for BReps with multiple faces.

Loft tends to create "surfaces" that contain multiple segments. Those obviously cannot be converted to a single UV domain. Sweep2 can be a better in this case, because it constantly creates single, continuous surfaces (afaik).

hi mario:

thanks a lot for the tip, your sollution works just fine, I was wondering, is there any way to tighten the surface, Im attaching 2 images, the first one is a tight loft, the second one is the result of the sweep 2 component, is there any way to get the same result with the loft and the sweep2 components?

thanks in advance!
