Setting the multiplicity of a constraint property (SysML)
By default, a new Constraint Property has a multiplicity of 1.
To determine the multiplicity of a constraint property:
1. Open the Constraint Property's Property Pages.
2. Click the Options tab.
3. The multiplicity is shown in the Multiplicity list.
To set the multiplicity of a constraint property:
1. Right-click the Constraint Property, point to Set, and then click Multiplicity.
2. In the dialog, from the Multiplicity list select the required multiplicity.
If you select Use Defined, specify the required multiplicity in the text box. For example, for a multiplicity of 2 to 4, type 2..4.
3. Click OK.
If the Constraint Property is a real redefinition, the Multiplicity is set for the Constraint Property in context, without changing the Multiplicity of the Constraint Property that is redefined by the redefinition.
