Assemblies Options

Specify assembly options, including options for Large Assembly Mode.

To customize Assemblies options:
Click Options or Tools > Options and click Assemblies.
Click Reset to restore factory defaults for all system options or only for options on this page.
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).
Optimize component placement when adding mates If selected, places components in more logical positions on the screen and relative to other components when you create mates.

If cleared, one component in the mate might be placed off screen, or hidden behind or within other components.

Allow creation of misaligned mates Select to allow creation of misaligned mates.
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.
Update model graphics when saving files Prevents display list data from becoming out-of-date. Updates model graphics data for components that are edited in-context, when you save assemblies.
Automatically check and update all components in Large Design Review Scans all components after an assembly is loaded and checks whether any components are newer than the parent assembly. If so, the latest graphics data of these components is used to update the counterpart in the assembly graphics data. This procedure is time consuming.
Update out-of-date SpeedPak configurations when saving files Automatically updates SpeedPak configurations. You can lock this option in the Settings Administrator Tool.

Use this option on top-level assemblies. This option does not work for subassemblies.

All Update all out-of-date SpeedPak configurations.
None Do not update any out-of-date SpeedPak configurations.
With Rebuild on Save mark Update out-of-date SpeedPak configurations that have the Rebuild on Save mark .

Opening large assemblies

The selections you make under Opening large assemblies apply only when Large Assembly Mode is on. Specify 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 specified automatically when Large Assembly Mode is activated.
Use Large Assembly Mode to improve performance when the assembly contains more than this number of components Specify the number of resolved components above which Large Assembly Mode automatically activates when opening or working in an assembly.
Use Large Design Review when the assembly contains more than this number of components Defines the threshold above which Large Design Review Mode automatically activates when opening an assembly from the Open dialog box. When the number of resolved components exceeds the specified threshold, Mode is automatically set to Large Design Review. You can select another mode from the list.

When Large Assembly Mode is active

Select the following options to improve performance.

Do not save auto recover info Disables automatic save of your model. (Define in Backup Options for normal use.)
Do not rebuild when switching to assembly window Skips the message that asks if you want to rebuild when you switch back to the assembly window after editing a component in a separate window. 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.

Hide all planes, axes, sketches, curves, annotations, etc. Selects Hide All Types on the View menu. When this option is selected, you can override it by clearing Hide All Types on the View menu, then selecting to show or hide individual types.
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 preview hidden component Turns off the preview when you select hidden components in the FeatureManager design tree.
Disable verification on rebuild Overrides the Verification on rebuild (enable advanced body checking) option in System Options - Performance.
Optimize image quality for better performance Downgrades your image settings to speed up performance.
Suspend automatic rebuild Defers the full update of the assembly while the assembly is in Large Assembly Mode. Items after the Mate folder or the current editing feature in the FeatureManager design tree are not automatically rebuilt.

Envelope Components

Specifies the mode in which envelope components are loaded when you open an assembly. Select one or both:

Automatically load lightweight Loads all envelopes as lightweight.
Load read-only Loads all envelopes as read-only.
