in autocad mechanical, i used hatch to verify the attached profile is closed. when i insert into inventor, i could not revolve it. even i changed it to a pline, i still could not revolve it.
in inventor, i drew a circle, i can revolve it. a rec (use rec command), i can, if i draw a four line closed rec shape, i could not revolve it.
inventor just would not recognize the profile.
what i did wrong?
thanks.

Can you attach your file here?
Inventor isn't like Autocad and constraints are quite important.

I successfully revolved your shape. I'm not sure how you're trying to bring it into inventor but all I did was:
Open file in CAD
Window Select all lines
Ctrl+C
Start new .ipt in Inventor
Create Sketch on XZ Plane
Ctrl+V, select location
Revolve
And it worked.
Revolves here just fine.
I suspect you did not have Inventor set to Constrain Endpoints to create Coincident constraints on Import.
Sometimes it is best to leave the Apply Geometry Constraints turned off.
Show All Constraints on your sketch that won't revolve.

i used scatch ribbon manu "insert", "cad".
i followed your way, it worked. but i do not know how to pick an exact insertion point.
in my above way, the cad 0,0 automatically matches inv 0,0,0.
thanks.
JD beat me to it.. I'd bet thats your problem..

yes it keeps the same origin from autocad.. If you want it at a specific place either move the sketch or change it in acad then reimport.
Yeah the other approaches are the more formal and proper way to do it. Mine is just a quick work around. I don't have to import from cad all that often and when I do, I can usually get around not being constrained to the origin. Or, if I really needed to, I could apply a couple of driven constraints and move the solid back to the origin myself.

When you Import directly into an active sketch - you still have the Option to Constrain End Points.
The easiest way to move (if you don't first move in AutoCAD) is to convert the sketch geometry to a Sketch Block.
