distance scale factor

[vodabl]

Does anybody know is there command or option in autocad that will change the distance units scale, without scaling tha whole drawing?

 

I now that this is possible for dimensioning, but that is not relevant for what I want.

 

Let to be clear. If draw a line that is 30 units lenght, and I consider it will be in meters, so that would be default units for whole drawing, so I need now some command, or option that would change the distance scale, so when further use DIST command for inquiry palete, same line will be mesaured in 3000 units (3000 centimeters).

Welcome in the forum!

I would say that you ask for a nonsense; don't mix the units in the same drawing.

But If you really wish to do it, try to define a custom function to multiply the measured distance with a predefined scale factor. It is possible with Lisp or even with the Quick Calculator included in AutoCAD.

With Lisp, to multiply by 100, you will need something like:

(defun c:scaledDist()
(* 100 (getdist (getpoint) (getpoint)))
)

You may read in the FAQ about running Lisp routines.

I will let you to discover alone the other way, using the Quick Calculator.

Fuccaro is right, the "number" given when you measure is NOT interpreted by AutoCAD as any specific unit like metres or millimetres, it is simply a "drawing unit" and it is up to the user to interpret this an whatever way necessary.

 

I suggest you read through this tutorial in order to get a better understanding.

Long ago one of my math instructors set us straight on this topic saying something like this:

 

1 = 1

2 = 2

 

but

 

1 foot 1 meter

2 inches 2 centimeters

 

You see the quantity of units is not the focus. It could be monkees, bananas, fingernail thicknesses, kilometers or light years. It's the second part of your callout which requires the user to know what he or she is working with.

I think Autodesk have this mentality too... providing such drawings units as Parsecs, light years... etc
