Scale Issues

I mistakenly drew my drawing at 1/8". The easiest way I can figure to correct this problem is to reset the drawing to 1:1 and then scale at plotting. Can anyone explain how to reset the original drawing to 1:1 without changing all my Dims? Please

 

When you say you drew your drawing at 1/8", do you mean you drew it at
1/8"=1'-0", or 1/96 full size, or 1/8 full size?

If the former case, you need to scale everything in your drawing by 96
times, and if the latter, scale everything by 8 times.

When you say "reset the drawing to 1:1", what do you mean, exactly? How
would you do that?

The rule in AutoCAD is to draw everything full size. When you do that, and
you dimension properly, your dimension values show true distances. However,
your dimensions are probably all going to be out by a factor of either 96 or
8.

Without seeing the drawing itself, it's hard to give any more direction.

Thank you Thank you for responding. I am ready to cut & paste right now to get this project out. I did not draw at 1:1. I checked and my model is 1/8". Now if you have a quick way to plot my VP to show in each VP at the desired scale without changing the dimscale, that would help. I am re-entering the drafting world and forgot alot of learned behavior.
Thanks

 

I just rescaled the drawing to 96. Trying to send you the file but it is not going through. Too big even zipped.

 

Simply scaling your drawing up by 96x should make no difference whatsoever
to file size.

Hi. Sorry I can't be of more help, but I still don't know what you mean when
you say your model is 1/8". Do you mean 1/8 full size, or 1/96 full size?

Also, I don't know what scales your viewports are set to, and I don't know
what your dimension style looks like or what dimscale is set to, and I don't
know what the "desired scale" is.

Let's go back a bit. First of all, what version of AutoCAD are we dealing
with?

Next, are you aiming to plot from the model tab or from a layout? Assuming
the latter, is your layout set to plot at 1:1? Assuming it is, what scale is
your viewport set to?

Where are your dimensions? Model space or paper space? (If you're on AutoCAD
2002 or earlier, they should be in model space.)

When you enter DIMSCALE at the command prompt, what does AutoCAD come back
with?

No..the size is just large. I can't scale the drawing because it will change the DIMS. The drawing was drawn @ 1/8" full size. The plot VP set at 1/8". Now when I set it to 1:1 it is still off. Using 2005 and it is so new it scares me. Here is my dilemma:
1. Drawing at 1/8" full scale
2. Need to plot vVP at 1/8 & 1/4 respectively.
3. Taken to Kinkos who only can plot from a PDF.

Just not sure what to do. Oh by the way, I have to submit these to the City tomorrow. So I can either fix it now or go cut & paste
Any help would be appreciated.

 

I am plotting layouts with VPs

 

Sorry..DIMSCALE set at 4"..changed from 1"....too small

 

What's your dimlfac set to?

 

1.0000

 

Submit to the city as is. If you try to change everything now, it's likely you won't have anything "sendable".

After the dust settles, make an insurance copy of everything FIRST.

Assuming your drawings are on an Xref ( i hope they are), start the scale command, use 0,0,0 are the reference point and scale everything using a scale factor of 96.

You will probable have to reposition everything in the viewports after changing their scale factor to 96.

You should be able to salvage dimensions by redefining them using an overall scale factor of 96 (Make sure the text style used for dimension text has the text height set to zero).

You may have to reposition your dimensions to some base starting point.

Same goes for text notes etc.

Hope this helps. Reformatting is not that hard -just fussy and unrewarding.

 

Thanks. What I did was pain-stakingly reposition and zoom until the correct VP was properly scaled. This will not happen again

Thanks for all your help. i am sure I will have more questions in the near future.

 

<< The drawing was drawn @ 1/8" full size.>>

That phrase has no meaning in ACAD. Either it was drawn "REAL" size or scaled. If the element is supposed to be 20' long, did you draw it 20' long? If you didn't draw it 20' long, how long did you draw it?

When you say "1/8" scale", does that mean you set the dimensioning paramters to 1/8" scale, or did you scale the elements down to 1/8"?

The day before you're to issue the drawings is the wrong time to learn how to use the software.

 

I know the parameters of the software. The problem with 2005 to repair these issues is in the service pack to be installed.If Autodesk would stick to a standard of use we would not have as many concerns as listed on this post. Submitted the plans and they were fine LOL. but I am starting a new project now. Tell me...because you seems to know alot...I open my template, set the limits, and make sure I am drawing 1:1. Then I can plot to any scale per viewport. Nothing has change with my knowledge, just the software

 

I interpret what O.C. was beating on in his post as the misuse of terms. People still refer to 1/8" drawings or 1/8" scale, which is a throwback to the pencil and paper days. The more appropriate term for cadd is scale factor when discussing scale -but then there are some that still have trouble with the conversion process.

I put both scale reference and scale factor on my drawings just in case anyone is curious. Picked this up from looking at drawings in Model Railroader magazine where HO "scale" size drawings are 3.5mm = 1'-0" OR a scale factor of 1:87. Just so you know....

 

LOL..I do understand

 

<< I know the parameters of the software.>>

Then phrase you problem based on those parameters. The language you're currently using is most ambiguous.


<<If Autodesk would stick to a standard >>

Is there some change to ZOOM 1/96XP in R2005 that it no longer works??


<<Tell me...because you seems to know alot>>

Yes, sometimes I seems to know a lot.


<<I open my template, set the limits, and make sure I am drawing 1:1. Then I can plot to any scale per viewport. Nothing has change with my knowledge,>>

Nor mine, as long as you properly set the zoom scale factor of the viewports, to match you desired plotted scale.


<<just the software >>

We're getting close now. What changed in the software that prohbits you zooming to the proper scale in a viewport?

 

nothing changed. I believe when my objects were drawn, they were not drawn 1:1..I checked and all was drawn at 1/8"..how this happened, I don't know. I don't think there is a way to change a model space drawing to 1:1 without upsetting the cad home I think I'm stuck with that one

 

<<I believe when my objects were drawn, they were not drawn 1:1..I checked and all was drawn at 1/8"..>>

I can only assume by the sentence above, that an element that should have been drawn 16'-0" long has measures only 2".

If that is the case, then the dimstyle used must have had a DIMLFAC of 96. The remedy is reset the DIMLFAC of the dimstyle to 1 and scale everything 96 times.
