Reposition your viewport without disturbing your dimensions.

Robert A. Somppi explains how to circumvent a specific dimensioning issue in AutoCAD’s paper space.

"A lot of people who would like to do annotation in paper space (and even some who already do) think that there is a major stumbling block to that method of annotating your drawings: 'What if the view in the viewport needs to be panned? Then all my stuff is out of whack.'

"There is an easy way of doing this without making the viewport active. Assuming you are not changing the scale, you can do it without panning within the viewport. Stretch the viewport using your preferred method to get the desired view, then move the viewport and the annotations at the same time to the desired place on the sheet."

Notes from Cadalyst tip reviewer Brian Benton: Ever since paper space came out in AutoCAD r11 (circa 1990), there has been a debate over where to put your annotations (dimensions, text, etc.). AutoCAD 2008 introduced annotated text and dimensions, which really eliminated one argument for dimensioning in paper space in that your text in model space has to be sized correctly. This created a text and layer management nightmare. A major, and valid, argument against dimensions in paper space is that the viewport may change location, size, or scale, which would normally break your paper space dimensions.

This tip suggests, and I agree, that if you need to reposition your viewport use the Move command. Just make sure to include any paper space dimensions with it when you move the viewport. Also keep in mind that if the setting dimassoc is set to 2 and you snapped your dimensions to the model space objects, then your dimensions are tied to those object points, causing the dimension to move or adjust with the object.

I'm confused by the intent of this tip. maybe it is just the wording. We do all of our dimensioning and annotations in paper space. The very first thing you do before dimensioning is get your viewport to the scale and showing the content you want wheter it be complete view or a small section of you view. The very next thing you SHOULD do is turn the View Lock on to prevent scanning or zooming inside the viewport. This prevents things from going out of whack. Then, maybe the rest of your tip makes more sense.

i'm going to agree with mark's comment. the wording of this tip really threw me off, and I am not fully understanding the intent. but mark is right and I also dimension the same way. first, scale your viewport, then lock it, then add dimensions...

Thought both te Geometry and The Dimensions can be locked in different ways, I still find it easy to differ between what to put where in means of Model Space/ Paper Space: Dimensions are integrated with Geometry and for a few versions Annotations can be Annotative and sensible to Scaling. there are annotations that are also integrated w/Geometry. But Titles that are connected with Viewports may reside in the Paper Space altogether with the Title Block. dannyk

Yes, I agree. My tip is not very clear. I was trying to describe out a situation that I've helped people with quite a few times. You have annotations in paper space and the area that is shown in you viewport needs to be panned to the left for some reason. Some people would unlock the viewport, pan, then adjust the annotations. My tip tells you to, instead of panning, grip edit the viewport and then move the viewport AND the annotations at the same time to the proper position on the sheet. This keeps the annotations aligned to the model. Is that better?
