If attributes revert to an old style after using ATTSYNC, it may be due to the block definition.
To ensure correct updates:
Edit the block in Block Editor and modify attributes as needed.
Use the ATTSYNC command and select the block to update attributes.
Save and reinsert the block if necessary.
Use the BATTMAN (Block Attribute Manager) command:
Type BATTMAN and press Enter.
Select the attributes from the list.
Use the Move Up or Move Down buttons to change the order of attributes.
Click OK to apply changes.
Instead of setting options for every new drawing, create a template:
Open an existing drawing and configure the settings as needed.
Save the file as a DWT (Drawing Template) file.
Use this template directly when creating new drawings.
If block properties (line thickness, text height, orientation) change upon insertion:
Check the annotation scale settings.
Use MATCHPROP (Match Properties) to standardize line and text properties.
Adjust text height in Properties panel to ensure consistency.
