You create multiple solid bodies in a part file using modeling commands, or by importing one or more solids using the Derived Component command. Use the Move Bodies command to reposition solid body components.
There are three modes of moving bodies in a part file:
Free Drag allows you to move objects in any X, Y, Z combination.
Move along ray allows you to perform a linear move on objects.
Rotate allows you to set the angular rotation of an object around a central axis.
You can use each method as a single move, or you can combine move options by selecting Click to add in the dialog box window. Group multiple moves into one operation to consume the least amount of memory. Inventor records each move in the browser, so you can edit or delete moves at any time.
