BIM navigation: when a mouse and keyboard are no longer enough

A BIM model can contain thousands of components, multiple disciplines and a wealth of interconnected information. This brings major benefits for design, coordination and operations, but also creates a practical challenge: users need to move quickly and precisely through increasingly complex virtual spaces. Alongside the capabilities of BIM software, the interface between people and models is therefore becoming more important.

One approach is to divide navigation and editing between both hands. One hand uses a conventional mouse to select objects, draw or execute commands, while the other controls movement through the model. This is the principle behind 3Dconnexion's SpaceMouse. Unlike a conventional mouse, it supports movement in six degrees of freedom. Users can rotate, pan and zoom simultaneously to examine building components, technical systems or infrastructure models from different perspectives.

For everyday BIM work, integration with existing software is crucial. According to the manufacturer, more than 300 applications are supported, including Autodesk Civil 3D, Navisworks and AutoCAD, Vectorworks, BricsCAD, Bentley MicroStation, GstarCAD, Trimble SketchUp and Tekla Structures.

Programmable function keys can be assigned commands from the application in use. The software recognises the active program and makes the appropriate functions available. Users can check geometry, review designs and assess spatial relationships directly from the input device without interrupting navigation. The two-handed 3Dconnexion workflow also reduces repetitive strain on the arm and hand while improving speed, precision and productivity.

At BIM World, visitors can try the SpaceMouse and CadMouse workflow at the 3Dconnexion stand. The company will showcase its input devices at Stand 28 in the ground-floor foyer.
