hello everyone,
I am a research student, i had never used rhino 3D before. well, i have stared to use this software few days ago,
my objective is to have a printable texture (printable means texture with adequate volume) on just a top surface of the solid box, rest of the phase needs to be normal. (find image with prospective view only)
(this image is not a solid body its a poly surface and surface with naked edges, how can i convert this in to solid body)
i have used “extractsrf” command to extract top surface from the solid box body, then i have applied texture on the top surface using “Displacement” command.
my question is;
i am not sure , that the texture i have applied is printable or not. if the texture is printable how can i convert surfaces in to solid body?
when i applied this texture and then i found that whole body is converted to a poly surface, i have join them using “join” commend. consequently, texture is applied to whole body rather than just a single surface,
Hi - after you have applied the texture with displacement, extract the display mesh with the ExtractRenderMesh command. Then extract the border of this new mesh object with the DupBorder command. Scale1D the rest of the box object so that the walls extend above the edges of the mesh. Now use the border curve to trim the walls and extract the display mesh from walls and bottom object. Join all mesh objects.
HTH,

Do you intend to 3D print this texture? If you have an FDM-type machine, this looks like a perfect retraction torture-test, and a fine example of the ‘many islands’ problem . Recommend you rotate the part so the textured surface is standing vertical in the printer…
hello, WIm
i have tried to follow your instruction, and it is helpful for a while, but at the end when i check for naked edges, its shows around 152 edges are naked even after join command you can found that it into attached image.
Hello - it is hard to advise without a file to look at but it seems what you have is a mesh and a polysurface - in order to make something closed, all the bits need to be the same stuff - either surfaces/polysurfaces or meshes, one or the other.
I have tried this method and CAD design looks fine to me no naked edges. But i have one question, does the middle section under textured surface has any volume?
Hi - I’m not sure if that’s what you mean, but yes, the void described by the surfaces of a closed mesh has a volume. You can run the Volume command to check the volume of “solids”. In Rhino, “solid” only means that there are no naked edges.

by my method the distance, is 0.02mm and i have calculated the distance theoretically, which is 0.03mm. i need to double check which one is the correct one.
TIA
Hello - if your points are at an edge, as I think you show, then you can use the Distance command, with the Quad osnap on and the Project setting on in the OSnaps - assuming the current CPlane is at the base of your shape… Does that help at all?
You may want to make sure your settings in DocumentProperties > Units page > Display precision has enough precision to measure the small distance.
. Recommend you rotate the part so the textured surface is standing vertical in the printer…
