Dr. Geo User's Manual -- Executing a Macro-Construction

|  |  | Executing a Macro-Construction

### Executing a Macro-Construction

To execute a macro-construction, the user calls the `Execute pre-build macro` function from the icon or from the contextual menu in the figure view.

From the wizard dialog, the user selects the macro-construction. In the 2nd page, she selects the macro-construction from the list in the top area of the dialog. Once a macro-construction is selected, she can directly click on the input parameters in the figure. As soon as all the necessary input parameters are selected, the macro-construction is executed and the final parameters appear.

The user selects the input parameters directly in the figure

In our example, the macro-construction needs three input parameters (three points) and it builds a point and a circle. To execute our macro-construction, we need a figure with a least three points.

A figure with three points

Once our macro-construction is applied to these three points, we get the desired circle and its centre.
