For over 25 years Rcad Software Company has been providing software and CAD services for the design of bridges, culverts, consolidation with drilled columns and support walls, wooden houses, hydro calculations and processing of survey data. Dozens of projects to which we have been associated have already been achieved.(http://rcad.eu , http://rcad.ro).We created our own CAD system called RCAD, which is specialized in 3D and a large number of entities. We wanted it to be simple, to require low resources as memory, CPU and graphics card and that the same version may run on any Windows operating system, starting with Windows 98 to Windows 10.On RCAD we have made two applications: RTOPO, specialized for topography and VDAFS to DXF and NC, specialized in VDAFS file conversion and NC surfaces milling. And other applications will follow.We have not neglected classical CAD systems, like AutoCAD and IntelliCAD, for which we have made add-ons, such as:– Topography in AutoCAD,– Topography in IntelliCAD,– 3Dintersection for AutoCAD,– Developed (unfolded) Section for AutoCAD,– FURNIT Design of furniture,- GWB Get wooden beams, software for house designers.Besides these, we have 25 years experience in developing and delivering software and services in the design of roads and bridges. The software was grouped under the name of RROAD. Here are some examples: topographical and hydraulic calculations, automatic editing of drawings of roads, 3D design and reinforcement of bridges with beams, culverts design, reinforcement of drilled columns, reinforcement of walls and 3D animation.(http://rcad.eu/rroad/ , http://rcad.ro/rroad/)
