Drawing looks great but when I create a .stl it is broken

[Anonymous]

I have a drawing that I have printed about a year ago that I recently opened up and created a .stl file.  However, when I try and upload that, the 3d printers say it has no "curved" surface.  I've attached a picture of what they see.  Also, when I look at it on 3dhubs.com after uploading the file, I can see what look like exposed triangles.  Picture of that attached as well.  The pictures show up in reverse order to the text typed.

I don't see "any" of these problems inside of Fusion 360.

This is what I see in 3dhubs.com.  It looks like exposed triangles to me.

Hi,

I'm not really following you here ... is the second picture the one in Fusion? and before importing it, it was fine? ( first picture )

Stls don't have curved surfaces.  All of the surfaces are created with triangles.

Export your file and post it here if you need more detailed help.

I had to do the images like this because the forum software also "blew up" and crashed.

The first picture is the printer/hub who has imported the .stl.  You can see by his image that the whole thing is "solid", it doesn't look like a bowl.

The second picture is the .stl imported into 3dhubs.com.  You can see unlike what the hub/printer, it is "hollow".  However, it looks like exposed triangles inside of the bowl.

Here is what it looks like in Fusion 360

The problem is 360 seems to create a .stl that is separated from "reality" and/or it creates .stl file that is separate from reality.  It is as if you draw a picture of a triangle using Microsoft paint and when you print it out on the laserjet, a nice square is printed.

Can you export and post the .f3d file?

No, I don't know how to do that sorry.  However, strange thing is this "body(37)" as shown in the picture.  This looks like something new that Fusion 360 added to my drawing.  I don't remember it and I would have renamed it something less generic.  When I turn that off it doesn't seem to do much of anything except take off the texture inside of the bowl.  Do you know what that is?

On the File menu (toolbar) select Export, then choose 'Archive Files (.f3d).  Attach the output to this thread.

 First image shows that there are 2 objects z-fighting, meaning they have equal surfaces.

Funnel component has 2 bodies. One is a solid, which reflects the bowl/hub. The other one is a surface body indicated by the orange icon. I believe that is the body throwing off the 3D print software. It simply puts a top and bottom cap on that surface and then treats it as a solid. 

Right-click on that orange icon and choose “remove” from the menu.

then export to .stl again and report back the results from your printing/slicing software.

The Body-37 (1), orange thing was the problem.  I didn't delete it but I turned it off and the problem went away.

This surface was causing the whole thing to be solid.
