(Help) 3D Modeling Rocket Engine Nozzle Molds

[LinusLoveMe]

Hello all,

I'm trying to 3D Model and then 3D print molds for some custom model rocket nozzles. I've used 3D modeling software in the past for many projects such as Cinema 4D and 3DSMaxx, however this is my first experience using AutoCAD. I made a 2d drawing and then revolved it 360 degrees, however this apparently is not considered an exportable solid to an stl file. I understand why what I am trying is not working as technically I only have a surface not necessarily a solid, however I do not understand how to convert this into one. Essentially it's just a cone similar object (keyword similar) that I designed a 2D path for and want to revolve 360 degrees to make a solid. I attached a couple pictures from CAD and linked the .dwg file. The top of the picture is my attempt at making the path into a 3d solid and the bottom of it is the 2 paths that I want to make into 3d solids.

Thanks for the help, I know this is a very basic issue.

Cant open it because you're using 2018

 

I've personally never used AutoCAD to do 3D work. I usually use Inventor for that.

id use inventor or fusion 360 for that. Autocad isnt what i would use for this kind of thing

Use fusion 360
