Using The "Define Catalog Access" Window - Siemens COMOS Operating Manual

Entering the calculation formula
There are two ways to enter a calculation formula:
● Via the "Define catalog access" window
The window helps you to define a correct calculation formula. The software generates a
calculation formula from the user inputs and writes it to the geometry attribute automatically.
See chapter Using the "Define catalog access" window (Page 31).
● Manually

Using the "Define catalog access" window

In the "Define catalog access" window, define the calculation formula for selected attributes.
See also chapter Entering the calculation formula (Page 30).
Procedure
To define the calculation formula using "Define catalog access", proceed as follows:
1. Open the base object properties for pipe part catalogs.
2. To open the "Define catalog access" window, press the "F2" button in an attribute that fulfills
the following conditions:
– Is placed on the "3D geometry" tab or one of the "Connector <1-n>" tabs.
– The "3D" value is selected on the "Link" tab in the "Mode" list in the properties of the
3. Select the calculation formula in the "Function" field.
4. Define the parameters of the calculation formula.
See also chapter Overview of the calculation formulae (Page 32).
