The prompt
Step 1: main body (paste this first) Create a vertical reactor as one solid revolved shape around the center axis. Total height is 78 cm. Bottom part: a cylinder with 5.08 cm diameter and 60 cm height. Middle part: a cone that is 7 cm tall, going from 5.08 cm diameter at the bottom to 10.16 cm diameter at the top. Top part: a cylinder with 10.16 cm diameter and 11 cm height. All parts share the same center axis and are joined with no gaps. Step 2: side pipes (paste after step 1 looks right) Add a side inlet pipe with 2 cm outer diameter on the main tube, 5 cm above the bottom, pointing sideways (horizontal), 6 cm long. Add a side outlet pipe with 2 cm outer diameter on the top wide cylinder, 4 cm below the top, pointing sideways (horizontal), 6 cm long. Both pipes should open into the inside of the reactor. Step 3: bottom inlet Add a bottom inlet pipe with 2 cm diameter at the center of the base, 5 cm long, pointing downward. Notes: The 78 cm, 5.08 cm and 10.16 cm sizes come from your drawing. The 60 cm, 7 cm, 11 cm and all pipe sizes are my estimates, so please check them. The 30 cm bed height is not a shape. It is only the zone where the particles sit. In CFD you set this later, so do not put it in the CAD prompt. If you want to mark it, ask for a split line at 30 cm height. I made the model as a solid shape, which is the inside gas volume. This is what CFD software needs. If you want real walls, add: "Make the reactor hollow with a 0.3 cm wall." The wall thickness is not given in your drawing.
