Design Master HVAC is an integrated HVAC building design and drafting program that runs on top of AutoCAD. Drafting features include single-line and double-line 2D ductwork with automatic fittings and 3D ductwork. Duct sizing calculations include constant pressure drop, constant velocity, and static regain. Pressure drop in the duct system can also be calculated. Building load calculations are done using the ASHRAE CLTD method. More…

An add-on for AUTOCAD wich identifies wooden beams from 3D DWG drawings of wooden houses. The result of the program is a drawing with the identified parts (numbered and dimensioned) and a file of quantities that can be loaded into EXCEL. DWG or DXF files can be created directly in AutoCAD, or they can come from programs that can generate wood structures (such as the software: ArchiCAD, Chief Architect, Autodesk Inventor, Solidworks, Tekla, etc.).

An add-on for AUTOCAD or BricsCAD, for the triangulation of a set of POINTS, isolines, DWG to Google Earth, the volume and center of gravity of a set of bodies or between surfaces composed of 3DFACE. You can load a file of points having the format: Number X Y Z Code. You can make cross sections, longitudinal profile and color-filled contour map. You can determine the flatness of the surfaces and you can import and export LandXML file type! More…

Easy CAD Viewer allows you to view and print various AutoCAD drawings on your PC easily and quickly. It also enables you to manage 2D and 3D CAD drawings, such as to rotate, edit. Easy CAD Viewer works with AutoCAD DWG, DXF, DWF files of all versions as early as AutoCAD Release 9 and as recent as AutoCAD 2015. The software is more than a viewer; it converts DWG, DXF, DWF drawings to image formats such as BMP, JPG, GIF, PNG, TIFF, and TGA. More…
