Good Day!

Architect usually works like a skulptor.

Make surfaces, delete surfaces, connect surfaces and make new one from many.

In this file i try to find the way to make a form like this:

But i faced whith the problem to connect and smooth trimmed/untrimmed surfaces - because on trimmed face dividing not working. Whithout dividing not working CatmullClark Smooth in Weaverbird.

I found some solutions, but they do not working for this file (may be i do wrong scripting in component): http://www.grasshopper3d.com/forum/topics/trimmed-surface-domain

This great http://4.bp.blogspot.com/-IBiLv9P7Jrg/T6Xs9y7idTI/AAAAAAAAAOo/zThPj...

but not exatly because unclear - how to make "base" complex face (like star or circle) on initial surface :(

Weaverbirds smoothing operations only work on meshes. You can see in that definition you posted by Michael the final group is titled 'mesh and smooth'. You need to follow those instructions.

You need to join the pieces you need to smooth, otherwise gh won't know what to smooth together. You need to convert the joined geometry to a mesh for weaverbird. Then you need to choose a smoothing operation.

I have shown a quick a dirty method below if you are having trouble with previous. But

join brep > mesh brep > weaverbird laplace

Thanks a lot, Nick

I tried, but... not smooth

You need to 'flatten' the input to 'brep join'. (right click on 'b' and choose 'flatten')

You can see in your first panel that breps and surfaces are in different lists. So they arent actually being joined together. Once you have flattened it, putting them altogether, the component will know you want to join them all together. And it should work.

coooll!!! )))

how i can adjust strength of smoothing? Only by level (L) ?

Can i adjust area of smoothing ?

Well there are many different methods, in this one yes L is the number of times it averages the mesh vertices (smoothing). You could try some of the other weaverbird smoothing operations or subdiving operations instead of laplace.

If you use the shortcut ctrl+m in grasshopper it will show the mesh faces, which should give you a better idea of what is actually happening with each mesh operation.

I am not 100% on your goal or what you want to do with this, so at the moment you are using some very awkward shapes/geometries. Daniel Piker has recently released a component called 'mesh machine' which essentially will clean up your first mesh, which would give you alot of flexibility in terms of what to smooth.

in general i would advise you to experiment with weaverbird first, and get to grips with the idea of meshes.

Very intresting, i will try it, thank you.

I study GH for making parametric architectural sketches. Now i try to make this and try to find optimal method. Main question is how to connect different parts together. "Project+split+list item" to connect and "join+smooth" for smooth if needed.
