Scale up/down objects at the time user is drawing them?

Hello,

Once I saw a  third party application . One of its feature was very interesting ,which I want to simulate it . But don't know how to start.

They  had  these  commands  like  sc100 , sc50 , sc25 and so forth....

 

In modal space,

We enter sc100  command and  then draw a line in 1000 units  length.

Then if we enter sc50 command  and draw a line in 1000 units , the line lenght  is doubled . 

How is it possible ? What is the approach to have this. Could somebody give me  an idea what the program is doing?

 

Even at bottom left hand side of screen during drawing line ( the coordinate display ) in both cases shows  1000 . But on screen the length is different.

 

Thanks in advance for looking and thinking about me.

Regards,

Janet.
