paperspace dimension keep changing scale on its own

[Anonymous]

I have read old forum about dimension that keeps changing scale on its own, this is becoming sooo frustrating already and its affect our fabrication drawings already, please anyone knows if this issued been solve already?

Hi @mgarcesUX9HW 

I will talk about the one color6 marked dimension in your 'SAMPLE FLY OUT DIM.dwg':

"is this something to do with my dimension settings?"

No, it has to do with the knowledge about how it work, how to check - it is a user problem, not a software problem.

The first thing you have to check is the "associative" property,

so i opened your file, selected this dimension object and... it is NOT associated, just in parts.

Mistake found, end of the story.

If the dimension is select, i can see you set the dimension to 1. modelspace object and 2. a paperspace object.

It is impossible that this can work well, how should this work? If you like to create a dimension for modelspace objects,

you have to snap to the modelspace object, BOTH defpoints.

Please: Open your file, select the dimension object, check the current value of associative-property

you can see it in't "Yes", right?

Now, try to recreate the dimension well, by using the right snappoints.

PS: Why do you use annotative feature in you paperspace? Earlier or later you get needless problems and needless=don't do it.

Hi CADffm,

that dimension is the problem as you know and check, yes everything is correct as you explained and I know about it, if you read my previous post here, dimensions  was started correctly as set and everything is fine , i got correct dimension, everything is snapping on the model space object as supposed to be and dimassoc is set to 2.

However ( this is where the problem occur) when I edit the object, ( i went to model space, modify the object that was dimensioned in the paperspace) the edited part was not snap by any dimension on the paperspace.

after editing it I went back to paperspace, the moment im on the ps I can see literally that culprit dimension change in value! without even hovering on it. then in becomes disassociate, snaps on something else in paperspace, and the measure scale change in value!. what causing autocad to randomly change this value? thats what im frustrated about I have tons of lisp program I thought its the one causing it but my drafters have only LT and they have same issues  

  i have been using autocad since 1998 but i have encountered this freak dimension only since we upgraded to 2018. 

of course it a no brainer if you set dimassoc to 2 your dim is associative and it should snap on model space object, or unless you set dimassoc to 1 or 2 but you have set your scale factor as per your vp scale

and by the way as per this link

it said here one solution is to make dimension annotative,  so it is a knowledge base or a software glitch

another issue of fly off dimension when dragging the dim text see attached screencast

[cadffm]

Hi since-1998 ,

First and as i wrote: I will talk about the one color6 marked dimension in your 'SAMPLE FLY OUT DIM.dwg' only.

Thank you for the explanation, what explain why the dimension is not fully associated with the model.

(Associativity is not maintained if an associated block is redefined such that the edge that the dimension is associated with is displaced. And you works with more complicated structures: Nested Block + dynamic Block in once.)

Now, the next problem is DIMLFAC what is set to 16 instead of 4.
Also I don't know why it is set to -16 (not -4)

Without the knowledge of 'how was the dimension journey from birth to this dwg' i can not help,
i think it would be useful to have the previous version of your DWG (full associated dimension).

Do you have samples: DWG before(correct)/after(wrong) ?

Never heard before the the dimlfac setting switches without user input.

To change the dimstyle of an dimension object is also an "user input" process.

[mgarcesUX9HW]

Hi, thank you for your reply, see below thanks

1.) (Associativity is not maintained if an associated block is redefined such that the edge that the dimension is associated with is displaced. And you works with more complicated structures: Nested Block + dynamic Block in once.)   = yes  im having dynamic block because this will automate our drafting capability, so what would be the use of dynamic block if it will mess up the dimension, so this could be an autocad glitch? that needs to be address to autodesk? and yes mostly it happen when we dimension a block or xref object.

Now, the next problem is DIMLFAC what is set to 16 instead of 4.
Also I don't know why it is set to -16 (not -4) = the  sample drawing which i clouded and the dimlfac is 16 is the culprit dimension which change of it own, this the whole point of my post, please take look at the video i attached which literally i just drag the dimension and the dimlfac changes

Never heard before the the dimlfac setting switches without user input. = look at my video, this is what  puzzled me  why are this dimension fly off without user input

thank you for your reply hopefully I get this resolve as its hurting our drawings as well as our fabrication,

1. Loosing associativity
>"so this could be an autocad glitch?"
Is it a glitch if it is known and documented?

>"that needs to be address to autodesk?"
No, it is known and documented. What i wrote in brackets first was a quote from the help[F1], not my words!

>"and yes mostly it happen when we dimension a block or xref object."
Thats the same, although Xref is much more problematic because the content is not part of the current file (where you add the dimensions)

2. DIMLFAC what is set to 16 instead of 4.
>" please take look at the video i attached which literally i just drag the dimension and the dimlfac changes"
>"look at my video, this is what puzzled me why are this dimension fly off without user input"
Sorry, but i can see only colored pictures (i mean your video), no chance for me to analyse things.
Please upload this file or another one with lesse objects, but with the same problem.

(the attached dwg is another on then in your video, right)

Nobody can see any dimflac setting in the video, or? 😉  (but of course I trust your statement)

You knowing: We need just a part of you file content, copy your file, delete what you want. Important is only that we can reproduce what you shows in your video.

Hi I have attached 2 files with magenta color dimension (the dim that is the problem) the file with filename: sample.dwg is with correct dimension, then the file with filename: SAMPLE-AFTER MOVING MAGENTA DIM TX.dwg is the same file i just save as after moving the text of the dimension, the dim changes when i drag the text. if this is not happening in your autocad then this could be something in our autocad or machine? thanks

[cadffm]

Good! And I see the problematic information in the object before also, but I have no idea how to "produce"  this situation.

Search an highlight, also repair would works i think, but first

i want to know how the dimensions were created end edited.

Nothing special?

chspace or Lispfunctions?

Created, layer locked, changed the viewport scale or similar workflows!? Can you remember?

Every re-calculating will show the other value..

Change viewport from locked to unlocked or change annotativ from yes to no,  no matter

because the issue is stored in the object data (so already in the 'sample.dwg').

If we can't find the source problem, i will offer you a tool to detect these dimension,

perhaps with an repair option.

[mgarcesUX9HW]

Hi thank you, I think it will mostly happen when we use dimcontinue and nothing out of the ordinary just making a dimension from paperspace. and yes thank you! if you can have a tool which detect this problem because for me  I cant visually check all the dimension of the drawing and only during construction they will catch it, but good thing the dimension will fly off a thousand times so there's no way for them to install following the problematic dimension, but it is a disgrace in my part 😞

[cadffm]

I will test with dimcontinue this weekend and share a tool for detecting that trouble dims.

[mgarcesUX9HW]

big thanks CADffm !!! I'll wait for it

[cadffm]

I had just 1 file with only 2 (patial) associated dimensions - but try it (just for detecting).
I'm curious if it shows too little or too much, or just right?
The line is just a test and unsightly written, I hide this in the VLX to protect the eyes.

[mgarcesUX9HW]

Hi CADffm,

this is great thanks, it can detect the problematic dimension before it flies out, but when I tried it with dimension that is already out of scale it cannot detect it can it? and ive tried our other dwg with the same problem also  is cant detect it either but thanks a lot for doing this, maybe a bit tweaking will make it perfect

[mgarcesUX9HW]

Hi CADffm,

I have check one of our drawing that have a problematic dimension and the culprit dimension is the dimension generated when I dimcontinue a disassociated dimension. but this is hard to detect everytime. 

[cadffm]

Hi,

>"but when I tried it with dimension that is already out of scale it cannot detect it can it?"
It's possible too, but not with that "Beta" version and if you have multiple viewports
in one layout with different scales, it needs a bit programming more.
Let us take the case up to the end and discuss it again at the end,
currently I'm interested in the problem to recognize early if the text is still right.

>"and ive tried our other dwg with the same problem also is cant detect it either"
Okay.. then share this file and i take a look (please mark the objects like before with a simple magenta cloud)

>"I have check one of our drawing that have a problematic dimension and the culprit dimension"
>"is the dimension generated when I dimcontinue a disassociated dimension. but this is hard to detect everytime.

Great to hear! But I can not adjust it. I assume that a detail in the description is missing.
Help me adjust the problem', step by step!
Maybe you create a DWG with a dimension <save the file> and then show via SCREENCAST how you do it?
(attach this DWG in the forum)

https://knowledge.autodesk.com/de/community/screencast

What version is runnung? Command: ABOUT shows the productversion

[mgarcesUX9HW]

hi sorry for late response, as I have encountered it most happen on dimcontinue and also when you tried to adjust the object that is being dimension. its happening randomly and hard to to capture every event, is there an lisp that check dimension per linear scale? and restore its linear scale by input? i can do it via quick select but only to see which one is not selected and of course per view port scale or a lisp that will tell you all the linear scale in the dwg in this case i can capture that there is a dimension not reflecting the correct linear scale? thanks

hi,

 i also have this recurring problem, i just resort to just exploding it to retain the correct value than seeing it in final print out in wrong value!

i want this prob be fixed

Thanks
