The 'Global Parameters' list manages all the parameters that you use for geometry and load data used in formulas.
Accessing the global parameters
You can open the list of global parameters in the following ways:
- Use the
button in the table toolbar. - Use the
button in the
Edit Formula
dialog box.
- Click Global Parameters on the Edit menu.
The 'Edit Global Parameters' dialog box appears.
Each table row manages a parameter. It is necessary for the 'Name' of a parameter to consist of ASCII characters and to be entered without spaces. The name is used to address the parameter in the formulas. Each parameter name can only be assigned once. In the 'Symbol' column, you can display the parameter with superscripts and subscripts in HTML format. If the symbol matches the parameter of a block (see image Adjusting Block Parameters ), it can also be used there for parametrization.
Select the 'Unit Group' of the parameter in the list. The list entry specifies whether the parameter represents a length, load, density, and so on. The unit groups are sorted by categories in the list.
The 'Definition Type' controls whether the parameter is described by a value or a formula. Depending on your selection, you can enter the 'Value' or 'Formula' in the following columns.
When entering a formula, you can not only use the parameters of the list, but also describe references to objects. Both options are shown in the image above. The usual JavaScript conventions apply, which you can also use for the formulas in table cells and dialog boxes. They are described in the Formulas chapter.
