After first selecting a part or multiple parts with either the Single or Window Select Tool, click the Scaling Tool to apply a scaling factor to the part(s). Sometimes an exporting application can inadvertently write out a model scale larger or smaller than what the part was designed in. This results in a part being translated into TransMagic very large or very small. For example a part designed in mm that was 100 mm long and written out to Meters would come into TransMagic as 100 Meters long! In this case applying a scaling factor of .001 would bring the part back down to mm.
