Perform a Dynamic Collision Detection

General

  • Collision detection makes it possible to simulate the design for assembly and the actual kinematics of the mechanism.
  • To make collision analysis sensible, first add any constraints to the assembly that determine the relative position or relative movement of the parts.
  • Dynamic collision detection of an assembly visualizes all the individual parts in a model which collide with the part being moved.
  • If there are static collision in the model, the dynamic collision detection will not always work properly. First, find collisions and remove static collisions. After then, the dynamic collision detection works properly.
  • You can choose the parts included in the collision detection by hiding the parts you do not want included.
  • The collision detection is alternately enabled and disabled when you select the button.
  • Pipe components are connected to each other by a handle linkage and set-on, and collisions between pipe components will be ignored in collision detection.

Move the Part to Perform Collision Detection

  1. Select Assembly | Collision Detection | Dynamic.
  2. Select the part with the mouse selection button and slowly move the part in the assembly by dragging the mouse.
    • When a collision is detected between the part being moved and another part, it will stop.
    • The part it collided with will be highlighted with a color in the model.
  3. Move the cursor back over the part being moved and continue moving it.
  4. To stop dynamic collision detection, select again Assembly | Collision Detection | Dynamic.
