Model Space vs Paper space
Model Space vs Paper space
(OP)
Hi,
I am new to AutoCAD, and the version I am using the learn AutoCAD is version 2000. I am using Windows XP Home Editon SP2.
About Model Space
Many books say ALL drawing is done is model space FULL SCALE. One unit in Model Space is equal to one unit in real world. So if I have to draw a pipe that is 10000 feet long, I need to use LIMITS command to expand the drawing area in Model Space, so it could be AT LEAST 10000 feet in width, assuming I draw the pipe horizontally?
I wonder if this "FULL SCALE" thing is a preference many people adopt, or is it really how AutoCAD works? If it is the way AutoCAD works I really cannot appreciate how this could be convenient. If I were to draw some huge, wouldn't most of my time be wasted navigating through the mess?
About paper space
I have no idea what this is. Is it just used to show how the plot will look like on paper before actually starting to print stuff? I know you can do something called viewports, I am talking about the big picture here.
Anyone please enlighten me. This is the most difficult concept I encounter since I started teaching myself AutoCAD.
Thanks

RE: Model Space vs Paper space
Having looked at the links you provided, and some other articles I googled, I feel there are two different kinds of interpretation of being "full scale."
First one
Using the same example I mentioned in my post, which is drawing a 10000-foot pipe.
The length of pipe drawn in the Model Space, if you use a ruler, would be exactly 10000 feet long. This is my first understanding of drawing full scale or full size.
Second one
Users need to choose what ONE drawing unit in model space stands for. If the user chooses to let one drawing unit represent 100 feet, then the so called full size /full scale drawing would only use 100 drawing units.
I am not quite sure which one is the correct concept used in AutoCAD, not both are wrong.
Thanks
Never cease learning.

I believe this is the general CAD recommended practice, & should really make sense once you get familiar with it.
