Large Assembly Mode

Large Assembly Mode is a collection of system settings that improves the performance of assemblies. You can turn on Large Assembly Mode at any time, or you can set a threshold for the number of components, and have Large Assembly Mode turn on automatically when that threshold is reached.

While using the Open dialog box to open an assembly whose number of components exceeds the specified threshold, Mode is automatically set to Large Assembly Mode, but you can select another mode from the list.

You specify the threshold on the Assemblies page in System Options. In addition, you can specify the following Large Assembly Mode options there.
  • Do not save auto recover info
  • Hide all planes, axes, sketches, curves, annotations, etc.
  • Do not display edges in shaded mode
  • Do not rebuild when switching to assembly window

To turn Large Assembly Mode on or off:

Click Large Assembly Mode (Assembly toolbar) or Tools > Large Assembly Mode.

When Large Assembly Mode is on, Large Assembly Mode appears on the status bar.

When Large Assembly Mode is on, the following options become unavailable (grayed out) on their respective System Options page or toolbar, and are automatically set as described below. When Large Assembly Mode is turned off, the options return to their previous settings.

System Options page or Toolbar Option Status when Large Assembly Mode is on
Drawings Options Show contents while dragging drawing view Off. Only the view boundary is shown while dragging a drawing view.
Smooth dynamic motion of drawing views Off. Dynamic operations to drawings, such as panning and zooming, do not display smoothly.
Display Style Options Display style for new views Hidden lines removed is set as the default display style for new views.
Display quality for new views Draft quality. Only minimum model information is loaded into memory. Some edges may appear to be missing, and print quality may be slightly degraded.
Display and Selection Options Dynamic highlight from graphics view Off. Model faces, edges, and vertices are not highlighted when you move the pointer over a sketch, model, or drawing.
Anti-alias edges Off. Jagged edges in Shaded With Edges, Wireframe, Hidden Lines Removed, and Hidden Lines Visible modes are not smoothed out.
Assembly transparency for in context edit Maintain assembly transparency. Components not being edited retain their individual transparency settings.
FeatureManager Options Dynamic highlight Off. The geometry in the graphics area (edges, faces, planes, axes, and so on) is not highlighted when the pointer passes over the item in the FeatureManager design tree.
Performance Options Transparency High quality for normal view mode. While the part or assembly is not moving or rotating, the transparency is high quality. When moved or rotated with the pan or rotate tools, the application switches to low-quality transparency, enabling you to rotate the model faster.
Curvature generation Only on demand. Initial curvature display is slower, but uses less memory.
Level of detail Minimum. The level of detail is minimal during dynamic view operations (zoom, pan, and rotate) in assemblies, multi-body parts, and draft views in drawings.
Check out-of-date lightweight components Don't Check. Loads assemblies without checking for out-of-date lightweight components.
Update mass properties while saving document Off. Does not recalculate the mass properties on save. The next time you access the mass properties, the system will need to recalculate them.
View Toolbar and menu Shadows in Shaded Mode Off.
RealView Graphics Off.
