There is no easy way to find errors. There is an error dialog box, wich lists the ID numbers of the elements that are causing conflict, but that's about it. We can't do much with that information other than delete the elements and start again. Only by knowing more about the family editor with work, time and patience, you will get fewer errors each time.

 

The "can't make type" error usually refers to a set of dimensions that, combined, don't make sense or will produce an impossible result, such as when you have a negative value for a length, which Revit cannot resolve, when it is evaluated with the other values.

To expand on Alfredo's answer, open the family, and then go to the family types window, swap between each type in the family, and click apply each time.  If there are any parameters that are broken for one type, but not for another, this is where you'll see them.

 

Also, for wall-hosted families, flex the thickness of the generic host wall (while in the family editor) to make sure that the family moves appropriately relative to the face of the wall (especially important with masking regions or detail groups).

Yes and no.  When you switch between family types in the family editor, an error message window will pop up giving you a general idea of what the problem is.  The project environment is similar, but an error with a family will just say "Can't make type", but it won't tell you what the actual problem is with the family.  That's why you have to open the family in the family editor and swap back and forth between family types to find the error.

You should be testing your family as you are building it in the Family Editor by "flexing" it frequently as you build it.  I am not certain what your family is intended to do or how you went about creating it, but most experienced users will recommend taking some time up front to think about how you want the family to work, including determining what parameters will be needed to drive the change(s) between different types and the range of values each parameter can take.

 

Then, before modeling anything, you should start by placing reference planes to act as the framework of the family, and place dimensions tied to parameters on the reference planes.  As you add each dimensional parameter, test the full range of values for that parameter and make certain that the reference planes move as expected and that there are no combinations of values that create errors, such as zero or negative values for a dimension.  Once you have the reference plane framework in place and flexing correctly, you can then start to add the actual geometry, locking items to the appropriate reference plane.  Even as you do that, it is a good idea to flex the family after adding each new piece, to verify that nothing done to that point has caused any problems.  This may be tedious, but it makes it easier to isolate a problem, since it will most likely be the last piece you added, if the family flexed correctly just prior to that.
