: In a Top-Down Design approach, you can create a Skeleton Model to drive the assembly's geometry. If you scale the driving dimensions or sketches within the skeleton, all components referencing it will automatically scale and reposition themselves.
This method can sometimes scale an entire model by tricking the software into interpreting existing dimensions differently. Scaling an Assembly - PTC Community creo scale assembly
: A clever hack involves changing the model's units. By going to File > Prepare > Model Properties and changing the units (e.g., from inches to millimeters), you can choose to "Interpret" the dimensions rather than convert them, effectively scaling the entire model by the conversion factor. How to Scale an Individual Model : In a Top-Down Design approach, you can
