Aras Collide -
3D Simulation
ARAS Collide consists of a series of powerful simulation components designed to facilitate the prediction of all types of vehicle and human motion. These tools are integrated into the familiar and intuitive ARAS 360 environment to ensure ease of use.
ARAS 360 software engineers, working with Brian McHenry of McHenry software, have created an intuitive, unified environment for building a scene, animating an event, and simulating an event - all in full 3D.
For the first time, users are able to work in a full time 3D environment. Intuitively place vehicles and other models by dragging and dropping, then apply input variables in our simulation editor, and click PLAY. The combination of the ARAS 360 easy-to-use interface and powerful 3D engine will drive the McHenry software simulations instantly. This allows interactive editing to generate accurate and dependable results. This is the first time that true 3D simulation is available to users of a 3D drawing program. As such, the transition from mapping the scene with a total station, to creating the 3D scene model, to generating simulations, is seamless. As Collide is integrated into the familiar ARAS environment, you must have the ARAS 360 suite installed in order to run the ARAS Collide add-on.
Meshes
The ARAS 360 simulation system reads both the scene surface mesh as well as the vehicle mesh, predicting 
simultaneously the vehicle motion on the scene and vehicle damage dynamically.
Use the ARAS 360 Terrain Model
ARAS 360 software engineers have built the most powerful terrain mesh ever presented. Unlike other simulation software products that require the import of a drawing file, the interface to the simulation engine is immediately in place, and deadly accurate.
Below is our simulation component line-up.
ARAS Simulation Component Line-up
ARAS Collide models the interaction of 2 or more collisions and includes advanced editing options based on McHenry MSMAC.
Collide users can edit vehicle impact positions and orientations and get real time feedback of simulation trajectories. Get accurate damage profiles generated at impact. This is the refined version of the original SMAC program adapted to 3D by Brian McHenry and integrated by ARAS 360 software engineers. The 3D capabilities include reading complex terrains, sensing roll over conditions, and rolling appropriately. You can build your simulation environment in ARAS 360, and be simulating moments later. When you have completed your simulation you can record it just like any ARAS 360 animation – ready for court presentation.
