Scaling from full size drawings

Can somebody please help me with the following scaling problem when using Autocad 2000. For example, drawing a line relative to a point I would like to be able to enter as the relative coordinates the values taken from an external drawing multiplied by a suitable scaling factor in order to draw the line and then dimension to my scale size. E.g. I would like to be able to enter as the co-ordinates of the second point of the line the following input: @9*0.0885,0 where 0.0885 is my scaling factor for the X co-ordinate of the line but the system will not accept data. Where am I going wrong?

Many thanks

why are you drawing at a scale? In AutoCAD you should ALWAYS draw full size.

Hello Dave - The object is to be able to reproduce a drawing in a model makes scale from data extracted from a full size Works drawing.

why not draw it full size and scale once complete.

I think you might be able to use 'cal to launch the command line calculator but I can't be sure.

Yeah, 'cal would be the route to take. I think the only math you can do in the commandline as you are doing is divide, since autocad will just treat it as a fraction and approximate a decimal (or whatever your units are) amount. However, as dbroada said, if you MUST draw at something other than 1:1, just draw the entire thing, then scale. Make life as easy as possible for yourself.

Hi there - Yes, I now understand that the correct technique is to draw full scale and then apply the scale factor. Thanks to everyone who replied to my query.
