different curve types

Is there away to separate different curve types from a list. My list has planar curves and line like curves, I want to cull out or remove the line like curves. Any suggestions and if not can there be a future component to do so? Thanks.

You could probably cull the line-like items simply by attending at their string name:

if (input=='line-like) then Cull

Can you post the file?

Basically I'm using a voronoi cluster on a spherical shape, I want just the outside shell lines this way I can use those lines to split the surface of the sphere. I dont want all the inside voronoi stuff. So I figured since any lines inside the voronoi pattern are always straight I could somehow remove straight lines and keep only arched ones. I need a way to work for all closed freeform curved breps. essentially I will start with a sphere but mold it maybe in rhino or in GH. Maybe you can help me solve it this way of removing straight pieces or maybe you know a better way to go about it all together.

You will need this cluster:http://www.grasshopper3d.com/forum/topics/3d-voronoi-4

P.S. also I noticed when I use brep components (explode) I get an extra edge which is the line of the sphere, I have pulled out and labeled it in my definition, I need a way to make that go away easier as well if possible.

Connect the output of wherever your curves are coming from to a panel. Bring down a Math>Script>F(x)1 component. In 'x' goes the output of the panel with the curve types. The function would be:

Contains(x,"Planar")

WOW cool, but correct me if I'm wrong, don't i need line like not planar, the arced lines are still planar. So would i type "line-like"

I was just responding to your original post.

No, you want "Line-like"

Great tip, thanks.

Hey

I tried out the above defination, but i cannot get the F(x) to work with Contains(x,"Planar) since this is also an older threat is their got any change to the way u make F(x) ?
