Planar Surface Component

Hi,

I am a little disappointed that the planar surface component doesn´t work like the used icon is promising.

The icon shows a bunge of curves and lines which are overlapping at the end. Of course they need to be planar, but in GH it does not work with overlapping curves.

Is there a trick to activate this function? I hoped this component will work similiar to the "boolean" curve in Rhino which creates a closed curve based on a bunge of overlapping curves - no matter if open or closed.

any tips or workarounds are welcome....

thanks

Hi Michael,

the idea is nice, but it doesn´t work in my case.

Just take a look at the definition....

works for me just fine, I am getting missing component errors when opening you file. Are you on latest release?

Hi Michael,

I have .0066 installed.

Here are the different results:

The main problem in your definition is that in some cases the component surface split doesn´t work.

Maybe it is a bug an Mr. GH can solve that....

Michael an people hi!

Could you help me with a doubt?

I'm also trying to do surfaces from curves exactly as the first file, but in my second file I couldn't understand what is the error, cause the component made surfaces only in few curves. What can I do to solve this?

***need the Rabbit plugin to open the files***

the problem was that the curves weren't planar

don't use region difference, best merge curves and use planar srf

Felipe, actually when you unlinked the offset component at the "surface" group (which that you wrote "i didn't understand this offset"), the shape stopped to do the radial offset (and it was becoming the curves not planar i think!), but i need to offset this to transform the shape. Try to slide the red rectangular linked to Amplitude(A)to see what happens on radial shape4.gh file. Could you help me to solve this without unlink the offset?

I see what you want to do; I'm afraid it is not possible, in this deffinition you can see that the resulting surface aren't planar; I work in a slightly different definition that works
