How to Resize or Scale CNC Files24/11/2019


Resize your files Quickly

A common issue for most CNC users when it comes to files is scale, either the design doesn't fit within your required size, your material is to big/small, your materials thickness isn't quite as required (some slot designs do not have much tolerance) or you just wanna supersize your design. Worry no more - using a simple math's equation we can achieve the required figures in order to match our needs. The equation looks like this...
100/CurrentSize*RequiredSize
Lets explain this:
Firstly we start with 100 (whole number in percentage)
Then we divide that by our current size (be it a hole, a slot width or the whole piece)
Then we Multiply that by our required size (again be it a hole, a slot width or the whole piece)
this will then give us the Percentage in which we need to scale our design.

Heres a few examples...
  1. 1. Whole Design - Smaller (Artwork states Width is 248mm and we want it 200mm)
    100/248*200 = 80.645%

  2. 2. Whole Design - Larger (Artwork states Width is 248mm and we want it 200mm)
    100/200*248 = 124%

  3. 3. Resize Design based on required hole size - (Current hole is 4mm we require 6mm)
    100/4*6 = 150%

  4. 4. Resize Slot Design based on Material Thickness - (Design is for 1/8 (3.175) we require 1/2 (12.7))
    100/3.175*12.7 = 400%
