grid over surface or solid

Recommended Posts

Thanks for the reply... maybe i couldn't describe the problem. I've that mesh or surface that looks like a strange egg. And than I have the grid. I would like to put the grid on the surface from the top, so if the grid is on the body, from top view you'd see a uniform grid, same as if it was planar, but from the side views it is deformed of course...

i hope its clear enough now, it would be nice if you could help me solving this...

 

something like on the attached sketch

I can’t open the file attached in post #1 (2010 format, presumably), but if a SURFACE is indeed available – not just some sort of mesh – then there may be the option to THICKEN the surface into a solid, create a grid of Regions, and IMPRINT the Region/Solid intersections. A bit of a pain, but not that bad.

Dear Seant!

I think it could work out, but i'm not sure if my object is a surface? I generated the 3D mesh with another software from a point cloud. Could you take a look at the file if it can be thickened or not? I attached it in 2004 format!

Thanks a lot in advance!

Sadly, that is a mesh and not compatible with the THICKEN or IMPRINT command.

 

However, with the “DEFAULT” layer present, I’m inclined to believe Rhino3d was part of the workflow. If that is the case then Rhino can generate the grid with its “Contour” command. See sample.

Using F2S.lsp (by Bill Gilliss) you can convert the mesh to 3DSOLID.

Steps (working in ACAD2009 - there is a better working UNION-command):

1. Explode the mesh

2. Use F2S.lsp

3. Rotate the UCS, so that the old y-axis becomes the new z-axis

4. Use F2S.lsp

5. Rotate the UCS, so that the old x-axis becomes the new z-axis

6. Use F2S.lsp

7. Intersect the resulting 3 3DSOLIDs

8. Notice the failure in 3D-Modelling (there is one corner "wrong" modelled)

To correct this

9. Use the symmetry: Cut the wrong half-3DSOLID by SLICEing

10. Get the 2DSOLID-egg by MIRRORing and UNIONing.

PS.: cannot attach the dwg-file - 1.6 MB
