I am in need of a template letter that would include pros, cons and ROI for the purpose of purchasing Revit Architecture vs AutoCAD LT. RA is the only Autodesk software that currently has Sun path program included. I will be designing Residential Solar Systems based on this this data and will also require 3D capabilities. Does anyone have a template for such a letter and I would need help comming up with pros & cons. Thanks, Darren, Please CC any replies to me at dallen5@dow.com.
