Setting up a constraint parameter as read only (SysML)
By default, a new Constraint Parameter is not set up as a read only.
To determine whether a constraint parameter is set up as read only:
1. Open the Constraint Parameter's Property Pages.
2. Click the Options tab.
3. If the Read Only check box is cleared, the Constraint Parameter is not set up as read only.
If the Read Only check box is selected, the Constraint Parameter is set up as read only.
To set up a constraint parameter as read only:
1. Right-click the Constraint Parameter, point to Set, and then click Read Only.
2. In the dialog, select TRUE to specify that the Constraint Parameter is read only.
3. Click OK.
To set up a constraint parameter as not read only:
1. Right-click the Constraint Parameter, point to Set, and then click Read Only.
2. In the dialog, select FALSE to specify that the Constraint Parameter is not read only.
3. Click OK.
