Assemblies options

Move components by dragging Select to allow components to move or rotate within their degrees of freedom when you drag them in the graphics area. When cleared, you can still move or rotate a component with the Move with Triad function or the Move Component and Rotate Component tools (Assembly toolbar).
Prompt before changing mate alignments on edit When changes that you make to mates result in errors that the software can fix by flipping mate alignments, the software asks if you want it to make the changes. Otherwise, the software makes the changes automatically (without asking).
Save new components to external files If selected, prompts you to name and save new in-context components to external files. If cleared, saves new in-context components in the assembly file as virtual components.

Large assemblies

The selections you make under Large assemblies apply only when Large Assembly Mode is on. Set options for normal use (with Large Assembly Mode off) as indicated in the option descriptions below.
See Large Assembly Mode for a list of other conditions that are set automatically when Large Assembly Mode is activated.

Do not display edges in shaded mode

Turns off edges in shaded mode. If the display mode of the assembly is Shaded With Edges , it changes to Shaded . When this option is selected, you can override it by clicking Shaded With Edges (View toolbar).

Do not rebuild when switching to assembly window

When you switch back to the assembly window after editing a component in a separate window, skips the message that asks if you want to rebuild. Skips the rebuild of the assembly even if you have previously selected Don't show again and clicked Yes (to rebuild).

When a rebuild is skipped, a yellow warning triangle appears on Rebuild (Standard toolbar), and a tooltip states Assembly not up to date.
