Create linked instances of objects

Modeling > Modify geometry > Create copies of objects >

Creates copies that are actually references to an original object. When the original is changed, the copied instances automatically update.

Instances are similar to file “shortcuts” in Windows or “aliases” on the Mac. They appear to be real geometry, but are actually links to the original object.

TipInstances take up less memory and disk space and display faster than real geometry.
