Continuing with my discussion of the AutoCAD Block Attribute Manager, I would like to discuss some of the tools you can use to change, and sometimes add, properties of block attributes. Multi-line attributes are great in certain situations such as drawing titles. You have the ability to add the multi-line feature to existing attributes but you cannot remove the feature if it already exists.
Another nice feature is the ability to create the block on layer "0", so it will automatically pick up the properties of the layer it is placed on, but then you have the option to change individual attribute colors for added emphasis.
The Text Options are very extensive, from changing the font and text height, to making the attribute text "Annotative". If you have ever had issues with attribute text either being too small or too large, the annotative option is a wonderful option.
Another use of the tool is to count the occurrences of blocks in the drawing. As you can see it will give you a separate count of blocks in model space and paper space (the complete drawing - model space).
I hope you are convinced, the Block Attribute Manager is a valuable tool to the AutoCAD user. The fact that all these changes can be made to block attributes without "Exploding" the block is the best reason for you to give it a try.
