What's the difference between modelspace and paperspace?

Theres an ATP course on this I think.

Heres the link http://www.augi.com/education/archive.asp?page=293

Its ATP066 that you want.

In modelspace you draw things at their true size - a microchip or a housing estate or a spaceship.
In paperspace you also draw things at their true size but this literally represents your plot onto a piece of paper, 24" x 36" or 841mm x 1189mm, say.
Paperspace viewports are like holes cut in the paper and allow you to see modelspace objects and control the scale at which you see them.

To try to put it in a nut shell, the simplist way is to remember that paperspace is what you see printing out and model space is what you draw on or make a model on.

Hope this helps

Thanks!!!!!!!!!!!!!!!!!!

There is another essential diference that everyone over-looked..
In model-space area, an object with an lineweight, let`s say, 0.60 will always have a 0.60 lineweight, not depending of the zoomlevel... In paper-space, the objects lineweight is directly dependable of the zoom-level..

Jaffarhu:
I am not so clear
do you mean that after using the "zoom" command to change the viewport in the paper-space,the lineweight will not be the same as the previous?am i right?
what is ZoomLevel about ?Is it about zoom-realtime,zoom-window,zoom-previous?

Not necessarily. If using ctb files to create lineweight, the "zoomlevel" has no effect. Polylines with a defined width will plot thicker or thinner, depending on plot scale.

So,the plot lineweight could only relate to the plot scale,as for the viewport in the paperspace is not necessary.but how to use ctb file to create lineweight?could explain plz?

Using ctb, each colour is assigned a thickness (in lay-terms that's the same as lineweight but it's not the same as acad's "lineweight"). In the old days, pen-plotters had a limited number (usually 8) of physical pens each of which could only produce one line thickness.
So, onscreen each colour represented the thickness of one pen.

Stb breaks the connection between colour and thickness. If you are just starting with cad, ignore ctb as stb gives you more flexibility.
