## Plot a metric file in 1/2" scale

I have a drawing that was drafted in metric with both metric and imperial dimensions that I want to plot in 1/2" scale. I know 1:25 is roughly 1/2" scale but is there a way I can plot in true 1/2" scale without converting the model space to standard? I'm using AutoCAD LT 2008.

I'm not sure you are describing things clearly enough.

Is the "1/2" scale" you are referring to really the 1/2" = 1'-0" scale? Or are you referring to a half-size plot?

I presume you are referring to 1/2" = 1'-0". (BTW, it isn't referred to as a "standard" scale, it is an "Imperial" scale.)

If so, you ought to be able to get the desired scaled plot using 125 mm:120 units in the plot scale area of the plot dialog. This assumes the layout was set up as a 1 mm:1 unit plot scale with a viewport at 1:25.

This might be a little more complicated than it first appears and a little more information would help.
1 Are you plotting from model or paper space?
2 Is the object drawn full size in model space?
3 If you are plotting from paper space what is the scale factor of the viewport?

If you are plotting from model space and the object is drawn full size use a plot scale of 1:24 leaving the units in the plot dialogue box as mm, or 1:609.6 with the units set to inches (25.4x24).

Assuming you are plotting from paper space and the viewport scale is 1:20 leaving the units as mm plot with a scale of 1:0.83333333 (20/24)

This magic number of 24 cones from the number of 1/2 inches in one foot"

Hope that this is of some help

Update:
Thank you for your response. Sorry I didn't update sooner, I guess a new baby will do that to you. I came up with a solution shortly after I posted.

The original file was drafted in model space in MM and I wanted to plot in Paper space at 1/2"=1' Scale.

Solution:
I created a custom VP Scale using .5 paper unit = 304.8 drawing units. (304.8 being the number of MM in 12"). I don't know if this is the best solution or if another way would work but it got the job done.
