Converting dwg to stl

Anonymous — Thu, 14 Jul 2016 17:52:08 GMT

I am trying to convert a 3D object I drew in AutoCAD 2016 from dwg to stl. I tried exporting but when I select the object and hit enter it removes the object from selection. Any ideas on what I need to do. I have attached the drawing.

It's not a solid, if it's a solid then STLOUT.

How would I make this a solid?

PEDIT, Join the lines, REVOLVE and use the line as pivot for 360 degrees; after that STLOUT.

Since I only have access to Autocad Lt, I'll try on the fly. It looks like you have a group of surfaces. Try joining your lines (those in the lower left corner of your posted dwg) into a polyline or 3D poly and then revolve them. It should make a solid.

Hi minsonc,

I agree with @Patchy. In order to get this to STLOUT you will need to crate this as a solid. I tried to convert your surfaces but had no success as it does not appear "watertight". I took your cylinder shape and created a circle and then offset it .5 to get the outer circle. I then used press-pull to pull it to the correct length. This object is a solid and allowed me to STLOUT.

I hope this helps.

I used PEDIT to join the lines before I used REVOLVE here is the new object it still would not work.

Because you pline is not closed.
