Have you modeled something that you are hovering over? Do you have a tool besides the Select tool chosen when you hover with its cursor? If the answer is yes to both questions and you are still not getting the inference engine dot and tool tip like shown in the image below, send me your model’s .skp file and I will see if there is a problem.
Yes, you have complete control over the holes and the toe kick. There are hundreds of default values you can change. However, at the moment it requires editing a file. We are working on a dialog box human interface to make changing these things easy. Hope this helps.
