Changing the scale of a drawing is something that can impact a little or a lot. Some quick thoughts for you to consider.
Titleblock (Paper space or Model space?)
- Paper Space - you simply update the scale of the the viewport and adjust the size of the viewport to match the desired area to be shown.
- Model Space - You update the scale factor of the title block to match the new scale factor
Text (Paper space or Model Space?)
- Paper Space - you simply move your text to the new locations and relative points for the annotation as things shifted due to the new scale factor
- Model Space -
- NonAnnotative - Scale text as needed for the new drawing scale.
- Regular text will need to be scaled from relative points for each piece or group of text. If the text is multiline but not Mtext you will need to scale the group of text together from a common point, other wise the text overlaps and does nor have the desired results
- Annotative text - Should scale just fine, if not you will need to set the annotative scale for the text entities in question. You may need to create a new annotative scale for the text entities, depending on drawing setup of styles etc...
Symbols and blocks (Paper space or Model Space?)
- Paper Space - you simply update the locations of the items to be properly representative of their previous locations prior to the new view port scale.
- Model Space - You update the scale factor of the blocks and/or scale up any symbols that are just line work relative to their placement points. If your symbols are all blocks it is pretty easy to use Quick select to select them and update all their scale factors to the new scale. (Hopefully they have a good insertion point defined relative to their definition).
Dimensions (Paper space or Model Space?)
- Paper Space - Depending on how the dimensions were created, some may have associative points maintain placement, some may not. Then you may be better off just re-dimensioning them as some may maintain the old scale factor. This should fix your leaders too.
- Model Space - Update the Dimension style scale or scales depending on if multiple dim styles are present, then save the sim style. That should do the trick for most of the dims, check the rest of the dims and make sure they all have the same dimscale applied, some of them may have had overrides. Leaders are separate entity types and if using quick select to verify scales you will need to look for these too. Dim style may resolve most of these unless overrides are present. Watch out for leaders that are just plain line work, probably a good reason to go ahead and replace those with an actual leader.
Good luck with your effort!
