Mounting points are used to define points, surfaces or lines on 3D objects on which other components can be placed. Mounting points can be used for the exclusive placement of a suitable handle on a 3D object. Example: Placement of the center of a mounting rail drill hole on the center of a drill hole on a support. A mounting point is therefore a snap point.

The placement of 3D objects on a mounting point can be controlled according to the following rules:

• Mounting points adopt the Z direction of a surface selected during the definition. The Z direction indicates how the object to be placed on the mounting point is to be oriented.
• The orientation of the XY plane of the mounting point can be additionally rotated in 90° steps or in a free angle in the Placement options dialog, which results in an additional rotation of the object to be placed there. A coordinate cross at the cursor allows for graphical control of the current direction settings.

Preconditions:

• You have opened a project.
• The layout space navigator is open and a layout space is open.
• The layout space contains 3D objects.

1. Select the menu items Edit > Device logic > Mounting point.
2. Move the cursor over the 3D objects.
   
   Points, edges or surfaces below the cursor are automatically highlighted. Snap points are displayed.
3. Click on a point on the desired surface.
   
   The mounting point to be defined is indicated by a coordinate cross at the cursor.
4. Using the shortcut key [Ctrl] + [Shift] + [R] you rotate the X axis of the mounting point perpendicularly in steps of 90°.
5. Select the Placement options popup menu item to specify any rotation angle for the X axis in the Placement options dialog.
6. Click to place the mounting point.
7. Enter the corresponding values in the fields Name and Description of the property dialog.
8. Click [OK].
