Dimensions in Layout Space are wrong

[selenaGRXGE]

I am a pretty simple user- I use AutoCad for interior design layouts and elevations. I recently started dimensioning in Layout space instead of Model space. I keep having a huge problem with the dimensions that I can't fix. Sometimes they are wrong in Layout space- they are off 1/16" up to 1/2". Not all of them- there is no pattern and they are correct in model space. This has happened on several different files now. I am attaching a dwg file. You can see in the Layout elevation the counter dimenstion is 2'11 3/4- but in model space it is 36" even. Any help is appreciated. I am using 2018 and have installed all updates

Hi,

turn on ANNOMONITOR and you'll see yellow question marks for all dimensions which are not really bound to geometry. And those dimensions can't show a value for a modelspace entity, that's why you get paperspace distance values shown.

Reassign these dimension objects (with object snap) and you'll see modelspace values displayed.

Hello-

I turned on the annomonitor and I see what you mean by the associated points.  All my dims were already snapped to points- but I pull them down to the bottom of the drawing.  You can see by my screenshot, one of the dimensions changed to 38' and the counter height is still reading at 2'11 3/4 instead of 36.  I don't think that is the solution.  All my dimensions are snapped to points.  Also- turning on annomonitor undid my "scale to layout" dimension style setting and turned the on to scale at 48.0

Hi @selenaGRXGE,

When I try to place a dimension in your layout I noticed that the elevation is not "flat" as the view it rotated slightly.

Perhaps this is causing some of the inaccuracies.

Hi John,

I believe the elevation is square- I turned on ortho and drew straight lines and it lined up perfectly on the x and y axis.  Also- if it wasn't square, it should still show the same dim in model space and layout.  You can see from my picture below it doesn't.

We can not check a stupid jpeg like a dwg..

"All my dims were already snapped to points- but I pull them down to the bottom of the drawing. "

Your dims with that annomonitor flag are NOT associated to other geometric points, or only

one of both sites.

Please create a new dimensionobject between two lines.

No annomonitor flag? Check also the properties palette -> associated=yes

Now delete one of both lines, the annomonitor flag appears (right?) and properties palette will show

another value of associated property.

At last you can delete the second line too, annomonitor flag still there and the association propertie value changed again.

But we can not know what you did to delete the association to the modelspace objects.

You wrote "move". Did you MOVE the whole dimension object? Thats the issue..

..and the wrong way. Stretch the dimensions and set up your dimension style to use fix length for extension lines.

I posted the dwg at the beginning of the thread- not just a stupid jpeg.  Feel free to move on.

Verify the viewport is scaled correctly.

[selenaGRXGE]

It is scaled correctly- most dimensions in the same viewport are correct.  This is a recurring problem where they are randomly wrong in the same viewport and random ones change to bizarre numbers.

Hi @selenaGRXGE,

So....I started digging into this 30 MB drawing.  AUDIT found 25 errors and Purge found a lot of zero-length geometry to be removed.

When I switch to modelspace and Zoom Extents it feels like I went into space.  I am in the process of cleaning up the stray geometry and when complete, I will check to see if the geometry in your elevations is drawn in plan view of the UCS and how this might affect your dimensions. You are not in a flat plan view as shown by the "custom view" in the top left corner of the drawing area.

I purged the whole file also, deleted as much as I could, and changed the view to Top view and no changes.  Dimension reads different in model space than paper space on the same points.

[selenaGRXGE]

But not all of the dimensions-- most of them are correct in both spaces

Hi @selenaGRXGE,

I moved your model content to a new file and then imported the layouts.  Please look at the drawing i have attached.  I changed the view with in the top left elevation viewport to TOP.  I have placed linear dimensions in both modelspace and in paperspace and they match.

This one dimension is not snapped to your elevation, you slid it down out of the way for cosmetic reasons but AutoCAD did not understand the action and it is now disconnected

Dame with that center-line dimension.

You also seem to have a couple of fudges going on (see my dimensions adjacent) using your own dimstyles. Nothing seems off, you seem to be self-inflicting as you move he dims out of the way of your drawing as I said for "cosmetic reasons".

Erase what you created and try again: there is nothing wrong with anything as long as you keep those dimensions attached to those objects and not slide them down.

[selenaGRXGE]

Yes- I saw that was happening when I turned on the annomoniter... but that isn't really the problem.  The side 2'11 3/4" dimension has no reason to be in-accurate- it is snapped directly to the points.  I am looking at the dwg file that John sent where it appears fixed.  It appears fixed, but I am trying to understand how it happened because I have a lot of other files that are affected.

[selenaGRXGE]

Hi John-

I see your drawings- the one counter is fixed, but the other two are still showing to be incorrect.  This is just getting more and more bizzare.  There has to be a setting that is wrong.

Hi @selenaGRXGE,

As I mentioned, I only corrected the view in the one viewport.  I made a quick video on one of the other viewports for you to show you the process.  I hope this helps.

[pendean]

I only opened your drawing, selected your dimstyle for paperspace, and dimensioned a copy of the viewport with no issues at all.

All seemed to work just fine with no problems at all.

I have no idea what anyone else did to your file: sometimes it is faster to do over that to expend so much effort looking for a reason something hiccuped in this complex program (especially when you self identify as inexperienced at the task).

Good luck.

Thank you, I see what you mean by each layout individually needs to be at Top. Problem solved!!! Yea!!

[ryan.moen]

Thanks for sharing the problem. I used to have this issue with more complex drawings. Among thousands of dimensions, it was really annoying when it happened. Do your best as others have suggested, and here's a tip: Edit the scale manually on 'Dim scale linear' and fix it permanently on your current drawing. If you use 'match properties', each small edit or adding text to your dimension will bring back the wrong dimension again.
