Annotative content in AutoCAD Architecture is sized based on two things:
- The scale factor of the current annotative scale (just like AutoCAD annotative content).
- The Annotation Plot Size, as specified on the Scale tab of the Drawing Setup dialog (AECDWGSETUP command). This is not used in AutoCAD annotative content.
The purpose of the Annotation Plot Size is to allow one set of annotative content to be used for multiple CAD Standards requirements, where the standard or minimum text size varies. For example, you may have one client that requires a minimum text size of 3/32" and another that requires a minimum text size of 1/8". Rather than having to create a duplicate set of content for each such unique minimum text size, all you need to do is set the Annotation Plot Size to that standard text size, and it will be applied as a factor, along with the annotation scale factor. From what you post, I assume that your Annotation Plot Size is set to 3/32" (0.09375).
AutoCAD Architecture annotative content is created such that one unit in the source content represents the Annotation Plot Size value when plotted at an assigned annotation scale. The 0.09375 scale factor you see on your callout content is applying the 3/32" Annotation Plot Size to the source content, where the attributes in the block definition have a height of 1 unit (1").
Additional notes:
- Some AEC Content, like callouts, results in AutoCAD Blocks being placed. These get the Annotation Plot Size applied at the time of creation, but are not affected by subsequent changes to the Annotation Plot Size. You would have to manually change the scale factor on the blocks to match the new Annotation Plot Size if that value is changed after placement.
- Other AEC Content, like schedule tags, that use Multi-View Blocks, not only have the Annotation Plot Size current at the time of creation applied, but will also change in size if the Annotation Plot Size is changed after they are placed. These items will show a scale factor of 1 in the Properties palette, rather than the Annotation Plot size value, but the Annotation Plot Size is still being applied to them.
- While I mention "minimum" text size while talking about the Annotation Plot Size, "standard" text size is a more accurate description. Content can be created that has text or attributes in the content that is less than one unit in height; any such text/attribute will be smaller than the Annotation Plot Size. Some of the out-of-the-box content has text that is smaller than one unit, so if the client requirement is a minimum text size, you will need to modify that content to make certain all text is at least one unit high. One example of this is the SCALE attribute in the Anno_Title_T1 block used for title marks.
- Text/attributes in the source content can be larger than one unit high, where you want text that is larger than the "standard" text height specified by the Annotation Plot Size. You can see this in the Anno_Title_T1 block used for title marks, also.
