Mike Shilton shares his method for determining the proper height for his text.
"When using multiline text in AutoCAD, how frustrating is it to get the text height correct on first insertion? A simple tip I often tell new users (and some advanced ones) is to first use the AutoCAD Distance command to pick two points that approximate the desired height of the text. The reported distance then gives you a great starting point for setting your text height when you go into the multiline text editor. Use this technique when inserting multiline text in both model and paper space layouts as the values will differ for each environment."
NOTES FROM CADALYST TIP PATROL: Getting text the proper size has been an issue since the beginning. There are many ways to do this. If you know what size you want the text to be when the drawing is printed, then you are headed in the right direction. Create a chart of text sizes you know work. Create blocks or templates that have text the way it needs to be -- that way you don’t have to think about it again once you figure it out. Use Annotative Text. This will automatically scale your text to a predetermined size.
