Setting the multiplicity of a block property (SysML)
By default, a new Block Property has a multiplicity of 1.
To determine the multiplicity of a block property:
1. Open the Block Property's Property Pages.
2. Click the Options tab.
3. The multiplicity is shown in the Multiplicity list.
To set the multiplicity of a block property:
1. Right-click the Block 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 Block Property is a real redefinition, the Multiplicity is set for the Block Property in context, without changing the Multiplicity of the Block Property that is redefined by the redefinition. For more information about redefinitions, click here
