Typically you don't draft these types of geometries. What designers do instead is sweep a surface controlling the draft angle with a dimension. For example you sketch a line with an arc off the line holding the line with respect to the pull direction of the plastic part. That sweep intersects with other surfaces to co join a form.
I designed a solidworks surfacing class for product designers a number of years ago but received very little interest... So we dropped solidworks training all together. Edited by: design-engine
Basic geometry rules dictate that draft can only be applied to 'single ruled' surfaces. That means surfaces that are only curved in a single direction. This means planes and cylinders mostly. Cones are single ruled as well, but are essentially drafted cylinders.
Think about single ruled like laying a ruler on the surface in the draft direction. It should make constant contact with the surface, if it doesn't it's not a single ruled surface. To add 'draft' to those surfaces, you'll have to use a technique like Bart described.
