Use Copy Object to copy or move geometry within a part file to composites, base surfaces, or a group in the construction environment. For example, you can create a copy or move geometry between the construction environment and the part modeling environment.
You can copy a solid to the part environment by using the Derive command..
If the original geometry changes size or position, the copied geometry does not update.
Use Copy Object to copy and/or move data between the construction and part modeling environment.
For example, when importing data from a file that contains multiple bodies, such as surfaces and solids, you may have to move surfaces to the construction environment to be stitched together to form a single part. You can use Copy Object to copy or move faces (or solids) to the construction environment, and then stitch the faces together to form a part. You can then copy or move the data back to part modeling using the Copy Object command.
