Paperspace, Layouts, and Viewports... Oh my!

Since paperspace was added to AutoCAD (in R12) users have been trying to wrap their minds around the concept. Long time users were of the opinion that they didn't need it and wouldn't use it (there seems to be a direct correlation between how long you've been using a product and how willing you are to accept new features.) Well paperspace is obviously here to stay. However, it still confuses its fair share of users. While brushing up on my AutoCAD skills through the AUGI Training Program I came across this explanation of the concept in the courseware for a class titled; AutoCAD 103-From Surviving to Excelling at AutoCAD (by Kenneth Leary):

"Paperspace can be explained like this. Imagine you have a blank wall, not a spectacular view is it? You would love to see your new Hybrid car outside so you cut a window in the wall. Now you can see the car, but you can’t see all of it. Cutting a bigger window would work but it’s a lot of effort so you go outside and back the car further away from the window. Now you can see the all of the car and all is good and right with the universe."

I want to take this opportunity to thank the folks who volunteer there time with AUGI. Whether it's moderating their forums or putting together courseware they are an invaluable resource for those of us using Autodesk Software on a daily basis. Thank you AUGI, Thank You.

Is this BIM? Ah, who cares.

(BTW, I have even resorted to cutting a hole in a piece of paper and placing it over a drawing to demonstrate paperspace. It explained panning in the viewport, but even this "visual aid" couldn't explain zooming.)

visual aid does show zooming [zooming and panning are "model space tiled"]. Leave paper (paperspace) where it is, bring eye to "hole" in paper, and you will see zooming. if you push your eye through the paper, you can even demonstrate "getting stuck" in paperspace.

That explains zooming in paperspace (i.e. with locked viewport) but the analogy is still lacking in an explanation of double-clicking a viewport and then zooming in the model space inside the viewport.

Although the visual of a student "stuck in paperspace" with the visual aid is darn funny.

That's post worthy.
