This Inventor How-To will demonstrate how the workflow for creating multiple Solid-Bodies in a single part file is quite simple in most cases. Mirror is a bit convoluted, but I’ll show you how to do that as well.
Firstly, download and open this file: Inventor_Multi-Solid_Body_Mirror.ipt
It is a very simple, fully constrained sketch that is ready to create a solid. Start by grabbing the Revolve tool from the Create Panel. Select the half circle as your profile then select the axis button if it is not already selected, and select the straight line of the circle as your axis. The Solids selector is grayed out because there are no solids as of yet, and the multi-solid button (arrow) will look active even though is not…
…leave the Extents at Full, and click OK to accept. You now have a single solid sphere. Expand your Origin folder in the Browser Bar, right click on the YZ Plane, and select Visibility from the context menu.
Click the ‘Mirror a solid‘ button…
This will bring up a new set of options in the dialog including the New solid option button. Click the New solid button in the upper right hand corner. The Mirror Plane option will now become the active command at this point, so select the YZ Plane that you made visible earlier. After you select the plane, the OK button will become active. Click it to complete the task.
You should now have a pair of Solid-Bodies in the Solid-Bodies folder as well as two spheres on screen…
That’s it. You mirrored a solid body to create a pair of solid-bodies using Autodesk Inventor. Have a great day!
