MESH UNION from 2 input MESHES + Smooth

Grasshopper
,
1

Good morning.

My question is.
I have created two intersecting MESH objects in my Grasshopper.
I want to use the command MESH UNION.
But on the function MESH UNION, when i connect in my two MESH OBJECTS, it wont work.
Whats strange is, if I bake my two mesh objects and then select source mesh in MESH UNION, then it works great.

So how can i put in grasshopper 2 mesh inputs into MESH UNION…
Im attaching a screen shot.

Second part of my question, when I have a combined output MESH, how can I smooth the entire shape a little ?

Thank you.

Hi Ian, it is difficult to say without a file. Sometimes meshes don’t join when they have coplanar faces. Or the meshes are in different paths. If that is the case, try to flatten the Meshes input by right clicking the Meshes input and hit Flatten.

If that doesn’t help, please post a file with the relevant inputs internalised.

For smoothing the mesh you can try Weaverbird plugin.

I searched this forum first and found this smooth mesh script from Daniel Piker

It works really well with my mesh :slight_smile: so I am very happy.

Only thing I noticed, when my mesh part is like a 2mm thick panel, this script gives me very intersecting edges.

Here is a screen shot of the two mesh components MESH UNION with Daniel Piker SMOOTH script. It makes a really lovely end mesh :slight_smile:

Thank you for all your help.
