mesh intersection problem

Z-SUITE/Firmware General Discussion

Hello.

I have a problem with the intersection of different mesh. Why Z-suite makes hole in that point?

This is an example.

(3d model with 3d smax)

Thanks

You need to combine parts into 1 solid. It will do this if there are separate solids in the same space.. I found this out when I had copied a part 1 too many times.. I had two parts in the same space and it showed blank like that..

Thanks for reply Kyle.

"R" and "n" are the same solid, are not 2 different part import in Z-suite.

This is another example. The "hearts" are one solid but in the intersections Z-suite makes holes... :huh:

Post stl files. I might be able to fix.

Thanks.

I've ran into this with files exported from 3dsmax. It's either the design itself, either the export, hard to tell. A 'unite'/'combine'/'make solid' command before exporting as stl might help. The 'hearts' stl, for instance: the bottom part seems 'open' to me. I could fix the missing intersections, but not the bottom.

L.E.: Kyle, any luck?

Marco: see attached pics. I'm no expert, just ran the stl quickly through netfabb. I guess you should make sure that you've deleted all the 'excess' lines/surfaces before export, even if they are not obvious or showing up.

Nope.. Even Spaceclaim won't combine it. When I convert to solid I get 2 solids overlapping.

Wrong modeling technique for sure...

First they are not solids..

Both pieces are open in the bottom, you can't manufacture surfaces.

Cap the bottom, then apply boolean union it should work.

Meshes are hard to edit without appropiate tools.

There you have the fixed file

You might want to try Netfabb pro it's one of the cheapest SW for AM.

Thanks guys and thanks Ahntlia for fix.

Yes, the problems are the excess surfaces under the intersections.

If I cup the bottom the problems still have, but if I delete the surfaces into the intersections, all is ok.

Thanks very to all. ;)

if you use 3dsmax you can do a proboolean in the compound objects

or you can use meshmixer

Thanks bounty.

3d s max proboolean (union) is a solution but I'm having difficulty...

it seems work not always well... only for regular (or not too many/complex) solids.

 
will let you know ;)

Dear Marco,

i turn your email address ?

thanks
