In Hero Lab, if you just want to print out statblocks for the various monsters from the Bestiary, you can load that monster from the Portfolio menu...Import Stock Hero. If you want to customize these monsters, you can add class levels, templates, or additional HD from the Classes tab. Then, you can generate a statblock from the file menu...Output Active Hero Statblock.
If you're looking to create new monsters from scratch, we offer two options. The first is the Bestiary Monster Creator. We've implemented the Monster Creation guidelines (Bestiary 1 pgs. 290-293), so that as you choose a Type and change the HD and ability scores, and then add the monsters attacks, special abilities, etc., we calculate where your creature falls on table 1-1: Monster Statistics by CR, which will give you an idea of what CR to assign to your creature. This capability requires the Bestiary 1 package within Hero Lab.
If you've already finished designing your creature, you can use our integrated editor (Tools menu...Launch Editor) to enter the stats you've chosen, and create a new race that way. Then, you can customize it with classes and templates and generate a statblock the same way you'd handle one of the monsters you had imported from the stock portfolios.
