Hicad Viewer - 2021

Moving the foundational graphics engine exclusively to OpenGL 4.3 requirements represented a massive shift for the software. Legacy versions relied on historical rendering protocols, which struggled with large numbers of components. By requiring a dedicated, stand-alone graphics card compatible with modern OpenGL instructions, HiCAD Viewer 2021 offloads complex geometry calculations directly onto GPU hardware. Panning across detailed facade layouts or rotating complex piping setups is smooth and efficient. Performance Optimization via Service Packs HiCAD 2021 SP1 - ISD Group

To present designs to clients and discuss technical solutions.

The shift to OpenGL 4.3 brings a critical hardware requirement. HiCAD 2021 and its associated viewer can only run on computers whose graphics cards support this OpenGL version. While the use of onboard graphics chips is theoretically possible if they meet the requirements, ISD recommends against using them from HiCAD 2021 onward, as their performance is typically insufficient for large and complex model drawings.

The viewer is compatible with a range of CAD software solutions, including HICAD, Autodesk AutoCAD, and SolidWorks. hicad viewer 2021

Includes precise tools for calculating 3D distances and 2D element dimensions, essential for production and assembly reviews.
