For every launch, it is essential to verify that the new product fits on the production line and does not collide with its surroundings at any point. In the BMW Group's Virtual Factory, the collision check is digital, automated and fast, using construction data combined with 3D scans. The movement and rotation of a vehicle through the production lines are precisely simulated, allowing the system to automatically check for possible collisions. What now takes just three days to simulate virtually previously required almost four weeks of real testing.
