Q - question

How to convert thick polylines to 3D solids?

A - answerPolylines with fixed width, closed polylines and circles can be converted (if the have non-zero thickness) to extruded 3D solids. Use the CONVTOSOLID command.

Extrude means creating solids using poly line.
If line thickness is normal or any other value, solid will create with inner core. (SOLID)
 
you can create shell by removing its middle core after that.
SHELL tool in 3d modelling.
I think it is equal for your requirement.
 
I'm sorry if I have miss understood.

Yeah this is the effect but your rectangle is open on one side, i want it to be completely closed from each side. 

So you have a Recangle with an inner cavity.


EDIT: I tried setting a new Work Plane behind the actual workplane and then extruding a rectangle and it works !!!! Just have to pick "Offset from Plane" and set a new plane in the thickness you need from the actual plane <3

Thanks for your help lovely dude! :)

Is this the affect you are trying to achieve?  In my example the rectangle is 200x400 and has a thickness of 20.  The "cavity" is 10mm deep.

I can't tell you how to do this using Inventor.  In AutoCAD there are a couple of ways to create a cavity in a solid object.  One way would be by subtraction.  The other way would be by using the PressPull command.  And depending on the object itself one could conceivably sweep or extrude a profile to obtain the desired result.

I tried to import the newest .ipt file but it failed for some unknown reason.  It might be an invalid file (corrupted?).

Alright, I uploaded a new drawing, which is just a rectangular. My prior example wasn't great.. 

https://www.dropbox.com/s/w0nb4ic2wrh7bmd/CADForum.ipt?dl=0

So I want to extrude this rectangular with a certain thickness, i.e. 5mm from each side to the inward.
So the remaining volumen is a cavity.

I hope I expressed what I need to know ^^
