Rebar Areas within Geometries

User Feedback:
Currently the implementation covers design intent or concept and NOT detailed design. For detail design we need the ability to place shapes, within given ranges (or areas) with the applicable spacing and all the relevant options (such as staggers, alternate bars reversed etc). This is a very good start but there is a long way to go for (dare I say it) those areas where intent is not adequate.
