Is there a straightforward way of measuring interhelical angles with 3DNA?

Unfortunately, the simple answer is NO.

However, you might want to refer to the 3DNA Nature Protocols paper recipe no. 4 on "Automatic identification of double-helical regions in a DNA–RNA junction" and explanations therein on how this problem is handled in not "a straightforward way" with 3DNA. Browsing the forums should also give your some hints.
