How to change a scale of a drawing without changing Z coordinates?

[MartaZ]

Hi,

 

I am trying to change a scale of the drawing. I use SCALE icon in AutoCAD 2008. It changes a scale, however changes coordinates as well. I want Z to have the same height.

 

For example:

 

Point A

coordinates

X = 575348.4593

Y = 154120.5144

Z = 34.8031

 

After changing a scale (scale factor=2):

 

X = 575305.9212

Y = 154124.8346

Z = 38.5552

 

Is it possible not to change Z? and have it as 34.8031?

 

Thanks,

 

Marta

What are you drawing?

[MartaZ]

It is a topographical survey plan of a quarry.

What exactly were you scaling and what did you use as the basepoint?

[MartaZ]

I was scaling a whole drawing. I tried to use different basepoints each time to check the difference. So it was a middle point of the drawing, as well as my point A. It always changes X,Y and Z.

 

When you use SCALE icon and type in: 2,2,0 (for X,Y,Z respectively) it changes Z anyway. The same if you type just 2.

 

Is there any other way to scale a drawing in AutoCAD?

Have a look here...

You can use the utility to rescale the Z coordinates back to what you need.

I think it creates a block and changes the XYZ scales; it may explode the entities.

Thanks for that. I will have a look

SCALE always used to be for enlarging or reducing selected objects proportionally in the X,Y,and Zdirections. So only one scaling allowed. If things have changed so that you are allowed to scale differently, then the factor to be entered is 2,2,1 if you want the Z to stay the same.

 

The old way is to make a block, then insert it with required separate X, Y & Z scaling.
