Separate shell from inner object
Hi!
Say we have an object that looks like this,
... with a hole inside, see section
I would like to separate the two objects so that I get a Solid for 3d print.

if you have solid object. then use "SLICE" command to split your object. it will allow to separate from cutting plane.
pls follow command information :-

Hi!
No, I don't want to split where the section is. The section only illustrates that there is a hole inside the outer shell.
I need to separate these two so that I get one solid that is the outer volume and another solid that is the inner volume.

Explode the solid, give the SURFSCULPT command and then select the surfaces that define the interior "watertight" void. This will create a solid object of the interior void.

Hi,
>> that I get a Solid for 3d print
May I ask a question just out of curiosity ... why is it constructed hollow when you need to 3D-print the object and so you have full control using the infill parameters?

Thanks Lee for the tip. I will try it out. Right now, the Solid is really complex, but I hope AutoCAD will not complain. I'll get back and accept solution or complain

Hi Alfred,
Yes, I need the infill to be controlled by the 3d Print application. I use Cura which comes with the Ultimaker 3 printer.
If the model is hollow, it gets filled up with support material which I think might be unnecessary. If I don't fil it up, I fear the model might end up fragile.
I wish there was a tool that could simply tell what to print from the outer shell.

To more easily select the interior surfaces I suggest making a copy of the hollow solid, explode it and then delete the outer surfaces leaving just the interior surfaces which can be selected with one window following the SURFSCULPT command.

Hi,
>> it gets filled up with support material which I think might be unnecessary
Otherwise it gets filled with your default material. ... and yes, I do understand that these are different settings, but why was the body constructed that way/hollow if you don't need it to be hollow? I guess that's one step before in the workflow of product design.
To close holes is sometimes much more complicated than to create holes.

I modeled a building in Revit, then exported as solids to DWG.
Then I Boolean-union everything.
Because of the wall thickness, I get the hollow volumes from that.
In 3dsMax, I can select the outer shell, invert and then delete what's left.
