I find most people follow the same scale factors as what CADaver has shown.

So standards scale and viewport scaling would be as followed;

Scale: Scale in dwg Viewport Text size

1=50______1=600units__1/600xp_____600

1/8=1-0___96__________1/96xp______96

3/16=1-0__64__________1/64xp______64

Ό=1-0____48__________1/48xp______48

3/8=1-0___32__________1/32xp______32

Mathmatically you get

Scale of X/Y=10 become Y*12/X or multiply the denominator by 12 and divide it by the numerator.

Example

1=50 is 1/50 therefore 50*12/1 = 600units

3/8=1-0 is 8*12/3 = 32units

I did find a neat little trick for scaling imperial drawings, but I found only I am new about it and practiced it.

My trick was to draw the titleblock at 1=1-0 there by eliminating the factor of 12 (twelve.)

Example using above;

Scale: Scale in dwg Viewport Text size

1=50_______50__________1/50xp______50

1/8=1-0____8___________1/8xp_______8

3/16=1-0___5.3 or 16/3___3/16xp______5.3 or 16/3

Ό=1-0_____4___________1/4xp_______4

3/8=1-_____2.67 or 8/3___3/8xp_______2.67 or 8/3

The mathematical equation for my trick is as follows

Scale X/Y is Y/X = Units or divide the denominator by the numerator.

Examples:

1=50 become 50/1 = 50units

3/8=1-0 becomes 8/3 or 2.666667

The downfalls to my trick is that you have to plot your drawing at 1=1-0 and most people dont understand how easy scaling can be this way. L

Thats is if I explained my little trick clear enough
