AutoCAD 2010/2011/2012 DWG Format

[#1]

I was never formally trained on 3D AutoCAD. I imagine this will be a simple question.

I would like to do all dimensioning in paperspace despite the standard practices of all the other engineers in my company. I have modeled a relatively simple 3D object and created a layout in which I have 2 viewports; one for the front and one for the right view. How do I dimension the object in each viewport without causing the dimensions from "viewport A" show up in both viewports?

By double-clicking a viewport, it seems I am then working the Model space, even though I'm still on the Layout tab, because anything I draw, type, etc. in that viewport will show up in the other. So when I double-click outside both viewports, i.e. to work on the layout itself, I cannot snap on to the object in either viewport for dimensioning.

What am I missing? Thank you in advance.

make 2 layers for dimensioning, shut off 1 in other viewport.

That brings me to my next question: how do you turn off a layer in one viewport without affect the layers shown in the other? When I am in "viewport A" and I shut off a layer, that layer also becomes invisible in "viewport B".

Somehow I can dimension in paperspace now without having to enter the individual viewports. OSnap isn't working quite as I'd like, though. But I think that is due to the geometry of my object and the way in which it was modeled.

Thanks for your quick reply!

It only works when it is "Though" the viewport while in paper space, use the icon that looks like the sun with a spare, click on it.

yup, I should have known that. Thank you!
