SCALING OF DRAWINGS IN AutoCAD

HOW DO I SET UP MY DRAWING PAGE TO A SCALE OF 1/100 BEFORE STARTING A DRAWING?

[ReMark]

When drawing in model space everything is drawn FULL size.  It doesn't matter if the object is the size of a postage stamp or the world's tallest building.  FULL size!  Do NOT draw to scale as one might do if he/she was manually creating a drawing on a drafting board.

 

You can address the topic of "scale" when it comes time to print/plot your drawing or make use of paper space viewports to which a scale can be assigned.  Are you familiar with paper space and the use of viewports?

And to add to that. FULL size is using whatever units you are using so if you measure in feet or inches that is what you draw (does anyone measure in yards?), if you measure in millimeters then use millimeters in your drawing or if you work in meters then use meters, don't measure in meters and then try to draw in millimeters it just gets confusing. Just make sure your units are correct in the -dwgunits command.

OK, well noted. I am familiar with paper space and view port. Assuming i am on my paper space as my drawing is ready for ploting, printing and so on, Using a single view port and I want to print it to a scale of 1/100, what should be my command on the command line? for example, is this correct; Z (Zoom) enter, S (Scale) enter, 1/100xp? and what is the meaning of XP attached to the 100?

Since you are using AutoCAD 2016 I would just pick the scale to assign to a viewport from the dropdown scale list.  If the scale you want to use is not among the default scales offered it can be added via the SCALELISTEDIT command.

The main thing in a layout is to create a viewport that matches your paper size in true size again, you can draw a rectangle or use a title block, so if I wanted a A3 sheet 420x297mm I would draw a rectang 10 mm smaller (hard clip printer limits) 400x285 then create a viewport inside it, zoom e then zoom around object then set the scale to 1:100.

 

You plot from paperspace but at 1:1 scale choosing that I want an A3 sheet. The viewport will come out at 1:100.

 

To confuse a bit more I used to use an A1 title block at true size 841x594 but generally plot A3 so in this case we do not change the viewport scale or paperspace scale but rather the plot scale as 1:2 this does mean though the reusulting A3 is at 1/2 scale so a 1:200 scale rule works.
