VariCAD is a computer program for 3D/2D CAD and mechanical engineering which has been developed since 1988 in the Czech Republic.
VariCAD provides support for parameters and geometric constraints, tools for shells, pipelines, sheet metal unbending and crash tests, assembly support, mechanical part and symbol libraries, calculations, bills of materials, and more.
Additionally, it offers many calculation modules for, e.g., springs, beam torsion, volume, mass and center of gravity.
VariCAD allows editing of DWG files without conversion using the Open Design Alliance DWGdirect libraries.
VariCAD Viewer is a free proprietary computer program for viewing of 3D/2D CAD files.
