It would be best to post an image of the design and where the features with draft are located.
Draft angle is a requirement for some types of manufacturing (i.e. injection molding).
There are many rules and guidelines to follow for the method of manufacturing selected. If you are simply making a CAD model to test a concept, draft angles may not be needed at this time.

The General Electric Design Guidelines for Injection Molding "book" also contains a lot of useful information for the design of mass produced parts:
