The Trace Transform option enables you to trace scale drawings using a digitizer as an input device. The movement of the pen or puck over the digitizer is converted to mouse moves. Button clicks on the puck or pen are translated to mouse button clicks.
When Designer is opened, the application checks for the presence of a digitizer on the system. If a digitizer is connected to the system, the menu items Set Trace Transform and Trace on Digitizer become available under Digitizer in the Tools menu.
The Digitizer Trace Mode is not available until the trace transform has been set up. To set up the trace transform, set up two sets of points - one set on the Designer workspace and one set on the digitizer tablet. The transform is set up so that every point on the digitizer is mapped to an equivalent point on the workspace.
