ViaCAD scale tool

reference line = 50mm (example)
First determine the width of the entity you wish to modify by selecting it and then by using the 'info' tools (measure point to point) or from the geometry info in the property editor.

To scale down

1. I have a line or entity of width 145.8mm long:
In the Scale options dialog box - enter in the factor X field - 50/145.8/1
Press enter - job done.

To scale up

2.I have a line or entity of width say 34.5667mm long, and I want to scale up to 87.432mm width:
In the scale options dialog box - enter in the factor X field - 87.432/34.5667
Press enter - job done.

Hope that saves some time for all those currently pulling their hair out with the scale tool. :)
