When things are set up right (for me), AutoCAD Rocks.    :D  :D

I fell in love with autoCad when they told me that I could throw my french curves away.

Keith noted that there is a disclaimer on their drawings to the effect “do not scale these drawings only use figured dimensions”. All of our construction drawings have this disclaimer on them. All of our A1 plots are plotted “Extents” (in paper space), so the finished plot may well be close to 1:100 or 1:50. The exact scale of the plot is irrelevant so long as there are enough figured dimensions to enable the bluntest tools in the box construct the building, slightly unfair, but you know what I mean.
For our own use, we frequently produce a set of A3 prints as desk copies as they are easier to handle than A1. Some contractors will also request A3 prints for the same reason.
The best example I have of a contractor trying to scale prints was a ground worker bringing a dirty soaking wet handful of near pulp and claiming that he could not set out the foundations from these prints!

For me it was the Leroy set and the pen cleaning station.

We generally address this issue by putting right on the drawing:

All dimensions shown are <unit of measurement>.

and

Do not scale drawing.

Then plotting to scale is a non-issue, right?

All dimensions in millimetres unless otherwise stated
Do NOT scale. If in doubt ask

is there anything unclear about that ?

if the drawing does not contain enough data to manufacture the part then the drawing is incomplete, and therefore, incorrect.

Not when it is required by law AND when the contractor will reject the plans if they are not plotted to scale.

Based on the other thread, you can't prove it wasn't.

You are absolutely right, but if the drawing contains even a meager amount of data that adequately describes the model, and it can be built using nothing more than basic construction techniques it is indeed correct.
Plotting to scale is a basic idea that produces viable and reproducable results that any monkey with a masuring tape can gather additional information from. If it is not to scale then he cannot.

As long as he doen't care that the additional information is inaccurate.  But then he's only a monkey.

If he's looking for "ballpark" numbers (which is the BEST that can be derived), he can interpolate from any drawing, "to scale" or otherwise.
