Object Visibility: Hide and Resume

It is often necessary to interact with components that are surrounded by or hidden from view by other components or surfaces. Autodesk® CFD provides a convenient way to hide entities to simplify accessing such components.

In the following example, the outer casing surrounds all of the internal parts. After changing the appearance to outline, we can see the internal parts, but it is not possible to select many of them because of the outer casing:

After we hide the casing, we can see and select the internal parts and surfaces:

After running the simulation, hide the outer casing and air volume to view results on internal components:

Set the type of entity to hide with the Selection Mode

To define the type of object to hide (volumes or surface), set the Selection Mode to the appropriate entity type.

While in Setup, the selection mode controls the type of object that can be hidden. Set the selection mode from Setup (tab) > Selection, or by right clicking and selecting from the Selection mode menu.

While in Results mode, volumes can be hidden by default. To hide surfaces, click View (tab) > Appearance (panel) > Surface Blanking. If the Surface Blanking control is not available, click the Results tab and then click the View tab again.

To Hide an Object

There are several ways to hide an object:

Left click on it, and click Hide on the context toolbar.
Right click on it, and select Hide.
Hover the mouse over it, and click the mouse button or keyboard-mouse combination for the current Navigation Mode:

Mouse Mode	Mouse Action to Hide an object
Autodesk® CFD	Ctrl + MMB
Autodesk® Inventor	Ctrl + RMB
Autodesk® Revit	Ctrl + RMB
CFdesign	MMB
Pro/Engineer	Ctrl + RMB
CATIA v5	Ctrl + RMB
CoCreate One Space Designer Modeling	MMB
ICAD/SX	Ctrl + RMB
SolidWorks	Ctrl + RMB
UGNX	MMB

Note:

LMB = Left mouse button
MMB = Middle mouse button
RMB = Right mouse button

Note: The entity touched by the mouse cursor will be hidden. It is not possible to hide an object if another visible object is in front of it.

To Resume Visibility

There are several ways to redisplay all objects:

Left click off the model, and click Show all on the context toolbar.
Right click off the model, and select Show all.
Click Setup (tab) > Selection (panel) > Show All.
Click the appropriate mouse button or keyboard-mouse button combination anywhere off the model:

Mouse Mode	Mouse Action to Resume all hidden objects
Autodesk® CFD	Ctrl + MMB
Autodesk® Inventor	Ctrl + RMB
Autodesk® Revit	Ctrl + RMB
CFdesign	MMB
Pro/Engineer	Ctrl + RMB
CATIA v5	Ctrl + RMB
CoCreate Modeling	MMB
ICAD/SX	Ctrl + RMB
SolidWorks	Ctrl + RMB
UGNX	MMB

Note:

LMB = Left mouse button
MMB = Middle mouse button
RMB = Right mouse button

Note: To resume visibility of objects individually, in the reverse order that they were hidden, hold the Ctrl key, and spin the mouse scroll wheel. Each "click" of the scroll wheel resumes the visibility of last object that was hidden.
