Scale tool introduction
Use the Scale tool to resize and stretch portions of geometry relative to other entities in your model. Activate the Scale tool from the Modification Toolbar, the Tool Palette or the Tools menu.
Keyboard Shortcut: S
Note: A Global Scale is an operation whereby the entire model is scaled simultaneously by applying a desired dimension to the distance between two points. The Scale tool is only intended to perform scaling operations on portions of your model (not the entire model). Use the Tape Measure Tool's global re-scale functionality to perform global scaling operations.
