Copying and pasting objects and re-scaling them!!

If you copy an object from another drawing onto the one you are working on say for example a pipe but you wanted to change the length from say 9ft into 12ft and the diameter from say 9" to 12" is there a quick way of doing this instead of having to draw from scratch?

cheers

Frazer:

Highlight the pipe, scale, pick a base point, scale factor 1.3333333333333333, enter.

Give it a shot. Oh, where are you posting from?

select the pipe with command "scale", specify a base point at any where, then select "Reference" subcommand of scale by typing "R", now specify reference length by clicking both ends of 9' or you can type 9' directly, now type a new length as 12'. It will works at both side length and dia.

Another way is to use an AutoLISP statement on prompter for small calculations (please take care to input real numbers instead of integers):

Specify scale factor or [Copy/Reference] : (/ 9.0 12.0)
