How to set the braking torque from the front and rear axles to the four wheels separately?
Hi ~ I use Vehicle Tools of MotionView 2022.2.1, and the Model Type is Car/Small truck. In Objects Disk Brakes, the brake torque is divided into front brakes and rear brakes. Since the default is left-right symmetry, the brake torque of the left and right front wheels will be the same, and the brake torque of the left and…

Exporting And Importing Systems To the Entity Browser in MotionViews 2025 Interface
Overview: Systems in MotionView are quite useful for creating well organized models. They can be modular sub-assemblies which can then be re-used in the same model or a different model. Until now, systems have to be exported to a file for future reuse (File> Export> MDL Definition). The trouble with this approach is…
