I’ve previously discussed how to use background masks with annotative text. Now I want to talk about using background masks in block attributes. Using the ATTDEF command, you create an attribute, but once it is created, there doesn’t appear to be any way to apply a background mask. The trick is to use multiline attributes.
Checking “Multiple lines” makes the “Default” value editable only by clicking on the ellipses.
If you click on these and type in your text (you can type just one line if you want), you can then highlight and right-click on your text and select “background mask” and apply the background mask settings.
Check “Use background mask”. I usually set the border offset factor to 1.2 or so, and the fill color to “use drawing background color”.
