Display Tool
Imported drawings are frequently very large. To obtain an overview of all the assemblies, the entire drawing needs to be brought into the field of vision. Clicking the Display tool displays the entire drawing on the screen.
If you first align the drawing to the coordinate system using the Center elements tool, you will easily be able to obtain an overview while work is ongoing (e.g. when selecting an assembly from the Object window).
