AI does not provide dimension tools by default. There are plugins and probably some well-intentioned scripts.
What Kurt said... You would have to draw them manually or use plug-ins/ scripts...
Thanks Kurt. I've been checking around but haven't found one yet. If you know of one and could let me know
I would appreciate it. Thanks.
CAD Tools is one such.
Why don't you just buy a competitive side-grade to Corel Draw? In the sign trade, you'll likely make frequent use of not just dimension tools, but also user-defined drawing scales, callout tools, and the abiility to specify text size by cap height.
Those are some of the reasons Draw fairly dominates the sign trade and some other specific markets.
