The full Envisioneer V11 Construction Suite program is 25-30 times the price as it also includes full 2D construction drawings and integration with other building and supplier software. The latest version is based on Envisioneer V11 being in effect the 3D part of the program. It is totally compatible with TFP 12-16 but with more advanced features of course.
Personal Architect is in effect a continuation of TFP V16 but several versions on.
