How do I change the scale of a drawing?

[Meglesniak323]

I cannot believe how many questions I find myself asking. I studied autoCAD for quite a while, but I am a little rusty now so I keep running into minor problems. Here I am trying to bring a floorplan from Adobe Acrobat (that my teacher emailed me). I am using AutoCAD 2009 right now. I am trying to bring in the plan (to scale) but I am stuck! Ive tried tracing it but I do not have the right dimensions and/or scale. Also, in the Adobe file my teacher sent is scaled at 3/32" but I am unsure how to make it 1/4" scale in Autocad. Actually, I am completely unsure how to even bring it into AutoCAD...

 

 

Any advice? Other than to buy the book!?

(Lol- its in the mail!!)

 

 

 

Thanks

This is what i would do,

Change the file from *.pdf to *.tiff or *.jpeg then insert it as a raster image.

from there select the image and scale by reference, if a doorway is supposed to be 4' select the image type in scale select one end of the doorway (as close as you can ge this wont be exact) then type r and select the same end of the doorway then the other and type 4' or 48

now you trace

to make it 1:4 scale you need to go into paperspace and create a viewport and double click inside and set the scale to 1:4 and pan to fit the floorplan in the viewport.

as i said this isnt exact, but its how i would do it, someone else will probably come along and tell you another way or two or three

Okay thank you! One more question - how do you insert a raster image? Otherwise I am about to follow that step by step...

Is that where I use IMAGEATTACH?
