issues exporting to stl

hi, I'm new as AutoCAD user, our team is trying to design an artificial medical ventilator and we try to do it with AutoCAD, the model attached is part of the pressure system, but when we try to export it to .stl the object cannot be selected and of course cannot be saved as stl, appreciate your help

Did you look it up in HELP, or notice the commandline feedback? STL exporting from AutoCAD requires your objects to only be Select solids or watertight meshes, your file and objects are not either one of those things. AKA they are not true 3D objects, just a bunch of lines, plines and flat surfaces.

You need to build an actual 3D model from SOLIDs first before you export to STL. Back to the drawing table my friend.

Thanks, I’ve been trying all as said in the tutorials and help, and still don’t get how to do it, I’ll keep trying

Mauricio,

Actually it is not very difficult in your case.
You already have profile in your drawing, all you need is to create closed polyline from it, then use REVOLVE command to create revolved 3D Solid.

I've done this in a few minutes. The resulting STL is in the attachment.
