solid model turning out hollow in slicer

thomas_cataldo

I am relatively new to onshape, but I am learning.  I am making a pretty simple model intended to be 3d printed. It should look sort of like a cast iron dutch oven that you would use in a camp fire, like a slightly flared cylindrical short bowl on short legs.  I made it in OnShape by drawing a circle, making a outwardly drafted extrusion (solid, 4") and then from the face of the extrusion I sketched another smaller circle and made a drafted extrusion ( solid,3.75", remove).  I sketched the legs as circles on the bottom and made them as added drafted extrusions.  In OnShape the model looks solid. But when I export it as an STL and import it into IdeaMaker, Simplify3d, or MeshMixer it comes out as a thin walled hollow structure, including the legs!

Help please!

This sounds like an issue with your slicer settings. Maybe your infill density is set too low, the model is too small (check that you export with mm as units from Onshape since most slicers use mm), or vase mode is enabled in the slicer?

A picture of what it's looking like in the slicer as well as a link to your document made public would probably be useful.

Additionally, to turn a solid into something with a cavity and walls, check out the shell tool (press Alt C to search, type shell to find the tool in the toolbar)

Were you slicing the part in vise mode?

Thank you and thank you for the swiftness of your response.
I thought is might be a slicer thing but the same thing happened in MeshMixer, IdeaMaker, and Simplify3D
The model is about 5.5" in diameter and the wall of the bowl is about 1/4" thick and the feet are 1/2" at the base. so it should be big enough.
I don't know why they imported in this order as they are numbered 1-6 but the Blue ones are screen shots from OnShape.  The red ones ar Image maker, model cut and a cross section of print preview,  The yellow ones are in Simplify3D with the model and it cut in half, not print preview

Thanks for any help you can provide

Yes, I tried it with vase mode on and off
it actually shows up hollow in OnShape even if I don't slice it in any mode
I had a friend export it from OnShape into his computer and it looked solid on the Prusa slicer.  He sent it back to me as an STL and for me it is still hollow, at least on the screen in IdeaMaker.

I am thinking of just printing and seeing what happens
but I did that with a previous print and it came out just the outer shell paper thin
