Exporting geometry to .STL

[abhaypatwa]

Hi,

I have a 3D geometry that i wanted to export as a .STL file. But everytime i selected the geometry to export, i keep getting the option "Select solids or watertight meshes: Specify opposite corner:." Although the command line does show that the objects have been selected. I've tried different ways of selecting the geometry but every time it shows the same thing. Any help on how i could export it? 

P.S - i was able to export it in other (.IGES, .IGS formats) but it doesn't seem to be working the same way with .STL

Thanks,

Abhay.

Select different ways but it's not 3d solid or W-T meshes then you have to edit your model.

I guess ill have to edit my model to a mesh/solid. Ill try doing that and get back to you. Thanks.

Attach your dwg file here if you can't figure it out.

Attached file.

Start using 3d commands e.g. cylinder, pyramid, loft  and you use extrude look carefully for MODE option.

Then all entities will be 3d solid.

These are really old and in Dashboard interface rather than the Ribbon interface, but you really need to learn the Solids/Surfacing modeling.  Much of this is easy step-by-step if you can figure out how to relate the old interface to the current interface.

Thanks for the reply! 

I'm trying to remodel the entire geometry in 3D. Willl let you guys know if i face further difficulties. 🙂
