One can change all of the instances that use a particular parameter
set to a new parameter set by changing the master cell of the
instances. The original template cell must be accessible, as for
changing individual instances. The procedure is as follows.
- Make the master cell the current cell. The easiest way to do
this is to select an instance of the master cell (one of the
instances to be changed) in a drawing window, and use the Push command in the Cell Menu. The master can also be
selected for editing from the Cells Listing pop-up, or by
giving its name in the Open command.
- Press the Cell Properties button in the Edit Menu.
This brings up the Cell Property Editor, which will list
the properties of the current cell (the master derived from a
template).
- In the listing, there should be an entry for property number
7198 named ``Tmpl Params''. If not, the current cell is not
a master derived from a template, or the template has no
parameters.
- Select the Tmpl Params property, and press the
Edit button in the Cell Property Editor.
- The current parameter string will appear on the prompt line,
where it can be edited by the user. Edit the string to supply the
new parameters.
- Press Enter when the modifications are complete. This
will rebuild the master from the new parameter set. All instances
of this master will contain the new master's geometry.
