The second value provides the percentage that can be entered into a copier - a value larger than 100 will make the drawing larger and a value less than 100 will make the drawing smaller.

The first value provides the decimal change.

Simply select the scale of your original drawing and select the scale you would like the drawing to be. The drawing must get (way) larger, so 360 divided by 24 = 15x or 1500% Scale Conversion Calculatorīelow, you will find a simple calculator to help with this calculation. Likewise, if you have a drawing at 1' = 30'-0' and you want to change it to 1/2' = 1'-0': Founded by Jimmy Wales and Larry Sanger on January 15, 2001, it is hosted by the Wikimedia Foundation, an American nonprofit organization. Here are some simple charts to help you convert drawing scale to scale factor, for working in CAD. The drawing must get smaller, so 64 divided by 480 =. To calculate the scale factor from a designed drawing scale, just increase the feet by 12. So as per the calculation scale factor is 48. Now that text scaling is set to 150, new data links are inserting smaller tables than before. Upset the portion & duplicate by 12 to get: 4/1 x 12 48. In AutoCAD, data links for tables were created when Windows text scaling was at 100. The scale factor is used to compare the scales to each other.įor instance, if you have a drawing at 3/16' = 1'-0' and you want to change it to 1' = 40'-0', you simply compare the two scale factors and adjust as required: To scale factor of 1/4 1 calculating scale factor drawing scale: Pick your scale. The trick is to use the Scale Factor, which appears in our CAD Scale Factors article. Changing from one scale to another seems like a complex task, especially if you need to convert from an architectural scale to an engineering scale.
