How to join different meshes with sense, how to make a mesh

[martinsiegrist]

Have you looked at the examples @DanielPiker posted in the Isopod topic?

Here are two meshes that cover a leg, using shrinkwrap to join both, it is very well seen in the top view that points are cut out and over the toes, I want this does not happen and that the areas of union between meshes is not noticeable as a junction area.

I’d like to know it this the result you wanted ?

No, because here you can see the junction area:

You can use the QuadRemesh to smooth here,

BTW, there is a guide about how to use QuadRemesh,

I’m going to try it. I have a question: is the “mesh offset” script something you wrote, or where can I get it?

Yes, this is a GhPython component based on Rhino Python,

See the difference with shrinkwrap in the junctions :

wiith quadremesh:

We also have the same problem with Quad Remesh as with Shrinkwrap—the fingers still protrude:

How can I access those scripts? When I type “Mesh Offset” in Grasshopper, nothing comes up.

Try to give a False to Hard Edges to remove the junctions

This indicates that the geometry at the bottom was initially not long enough, and you need to manually adjust the length here.

@manuel_mansilla Of course, you can also use Geometry Cache in Rhino to manually adjust local dimensions. Note that for easier size adjustments, I have converted the Mesh to SubD here,

this is very nice, I’m going to see if I can improve the workflow and see if I get what I’m looking for,

thank you very much for your help!

@jessesn

Now I have another issue: when I try to join the next two meshes, some faces of the lower mesh don’t join. How can I remove those faces? I don’t want to change the thickness of either mesh for now.

The union was done with Mesh Union followed by QuadRemesh

I don’t suggest you deal with this issue at the end. You should address the bottom part thickness issue before the initial ShrinkWrap. This workflow would be more reasonable. For now, you can only handle it manually, e.g. using Bridge to close the gap here,

Okay, thank you very much. I have another question: is there any way in Grasshopper to fill the spaces between the fingers? My goal is to obtain a planar surface without those gaps.

You can achieve it via Stitch and FillMeshHole
