Hi Friends, 

I have created the model in the picture in AutoCad, but I do not know how to create it in Inventor. In Inventor I Know how to extrude and draw 2d/3d sketches, but this simple model it is impossible to me.

Please any could help me?, it is a simple 3D part, no sheet metal or pipe. It is an structure.

Any help is welcome!. I have copied it sliced to make more clear the geometry that I am looking for create.

Create large tube.

Create new workplane offset from one of the 2 origin planes running the length of the large tube.

Create new sketch with small tube inner and outer diameter on the new workplane.

Extrude the region between the diameters using the "TO" selection and choose the outer surface of the large tube.

RMB on the new sketch and share sketch.

Extrude cut the inside region of the inner diameter of the small tube using the "TO" selection and choose the inner surface of the large tube.

Easier than that if the wall thickness is uniform.

Sketch large circle at origin and Extrude symmetrical (mid-plane).

Sketch small circle at origin on perpendicular plane and Extrude.

Shell and pick the end faces.

Done.

 

Slightly different process if you want a multi-body solids.
