| Specification of a dot-shaped mounting point, e.g. screw, rivet... Is required in drilling automation to approach the point. For long material, the center of the first hole should be indicated in the direction of the line up. The Z axis represents the point of contact between the mounting surface and the product (usually Z = 0). |
2 | M | Hole matrix (in mm) | Here you can enter data in mm for a linear fixing matrix. (e.g. for long materials: bus bar, wiring duct) | Specification automatically helps the CAE system to set fixing points depending on the material. |

Usage of Fixing Point, Fixing supply point (in mm):
The component receptacle of a product and the fixing supply point of a product fixed on it are overlaid during assembly planning.
The order of the fixing points is not determined. If there are several options for usable fixing points, the standard fixing should be specified as the first variant.
Type of mounting=carrier rail
For products that are fixed on a carrier rail, the fixing supply point is in the middle and upper edge of the carrier rail in the direction of alignment at x=0 on the device.
When fixing on carrier rail, usually no fixing point is required. The fixing reference is described by the fixing supply point.
Figure 21: CAx-Carrier Rail mounting
Type of mounting=direct mounting
Corresponding also for screw mounting, wall mounting, ...
The fixing supply point should be selected so that it can be easily positioned for line-up and dimensioning.
Figure 22: CAx-direct mounting
Type of mounting=bus bar fastening
The fixing supply point should be located on the top front edge of the top rail.
Figure 23: CAx-bus bar fastening
Type of mounting=front-mounting
Each type of mounting is to be defined here!!!
Figure 24: CAx-front-mounting
Mounting cut-outs
The properties can be used to describe a mounting cut-out for a piece of equipment. E.g. cut-out in the front for a measuring instrument or in housing walls for filter fans or for heavy connectors.
If mounting cut-outs in panels and or fronts (touch protection covers, doors) are required, information on the required measurements can be given here.
All positions are given as Axis-1D properties. Only the positioning values are relevant, the direction values are irrelevant. The X- and Y-values are decisive for the size of the cut-out, the Z-axis is to be selected equal to the value of the Z-axis of the fixing supply point for the cut-out in the panel/front.

6 | M | End angle | End point in degrees of the circular arc.
| Zero degree is "right" on the x-axis. The cut-out starts at the starting angle and runs counterclockwise to the end angle (polar coordinate system). |
