Printing to scale in for schools

I’m trying to print out a to scale drawing of my design. I set an orthographic scen and printed it at 1"=8’ to create an 1/8" scale. when I print it out it is not correct. the measurement of 60" in the drawing is measures to 56’ with a scale rule. What ame I missing?

Did you set the Camera to Parallel Projection?

I did

Can you share the .skp file?

When I open your file I see it is not set to the standard front view. Instead the camera is position high.

When I set the standard front view the model looks like this.

In the print dialog I’ve set the scale to 1:96 as you wanted.

Printing the PDF without scaling should get you the right dimensions.
