This new software was requested by an OEM partner, who did not want to develop it himself. ARES Sketch is floor plan sketching for tax assessment, especially in the USA where property tax is based on square footage and what each square foot is used for: patios, fireplaces, offices, etc.
It uses Graebert's CAD experience from SiteMaster, GIS from ESRI. It is meant to be integrated into CAMA, computer-assisted mass appraisal systems. It will be released by the end of the year.
It is not a sketching program like SketchUp, but does offer a simplified user interface. As a rectangle is drawn (which snaps automatically), it represents a floor area, like a room and a dialog box pops up for you to select the use. The goal is to add room areas quickly, including rooms within rooms. It can access online geographic images, on which you can sketch the rooms. It outputs in DWG.
