Extinguishing with Suppress in comparison with Hide or Ghost

The Suppress function is intended to be used to hide objects in the 3D scene that should not be visible and when it should be so over a longer period of time. This also has a positive impact on performance as fewer objects are depicted on the screen and even the file size is reduced.

Tree icon
An object hidden via Suppress has a white icon in the tree.

Keep in mind that there are more alternatives to Suppress, see more info about this at the bottom of the article.

Suppress/Unsuppress
Suppress can be activated and deactivated via keyboard shortcut [K] on a selected objectpart or assembly). The option is also available via the right-click menu on the object.

Unsuppress (multiple objects)
When more than one object is selected (via the history tree), the Suppress option is inactive (grayed out) and it is also not possible to turn off the Suppress function via keyboard shortcut [K]. Instead, you should use the Unsuppress function, which has the keyboard shortcut [Shift] [K].

For an assembly, three additional options are added;

Suppress Parts
Suppresses all parts in an assembly in all levels. NOTE! If a sub-assembly contains only one part, the assembly will also be suppressed due to missing content.

Unsuppress Parts
Only brings up the parts that are suppressed in the structure below the compilation. If there are individual assemblies that have been suppressed via Suppress , these will not be visible again. NOTE! These suppressed assemblies and all their contents remain hidden in the 3D scene.

Unsuppress All
Turns on all items that are suppressed in the assembly.

Suppress vs Hide - what's the difference?
The Suppress function is meant to be used for items that should be hidden more permanently over time, while the Hide function is a more temporary solution when things are in the way and should be quickly removed and then just as quickly brought out again.

Its keyboard shortcuts are different combinations of the space/blank key that, when used properly, give you more control in the 3D scene!

Configurations only use Suppress
When working with configurations, Suppress is used as the permanent way to hide items in a given configuration.

The 2D drawing uses both Suppress and Hide, but in completely different ways
Suppress is also reflected in the 2D drawing, where the object disappears from both views and parts list, while Hide has no such effect at all on the 2D drawing.

However, with the 2D drawing, you can use the Select Assembly to Project function to select individual objects to be depicted in a drawing view. You can also use the Hide function to hide objects in the 3D scene, which means that the 2D drawing "actively ignores" the objects that are hidden via Hide. This has nothing to do with the objects not being visible in the 3D scene, but that the views are instructed to actively not depict these objects.

‍

Ghost
The Ghost function is a kind of reference function that means that a part or assembly is displayed transparently and can no longer be clicked on with the mouse pointer or snapped against with handles from other objects or with TriBall etc.

Activate Ghost using the keyboard shortcut [G] or via the Tools tab. There are also options for managing the objects that are already set as Ghost.

The control for the transparency of an object set as Ghost and whether it should be possible to snap to it is controlled via Options, Part (at the bottom).
