In SolidWorks, you can eliminate interference between parts. Interference checking is automatic, and every part can be checked to see if it interferes with any other part. Interference problems are highlighted, and even the amount of the interference is re-ported. With SolidWorks you can also automate the process of hole alignment checking.
Checking interference in an assembly that is static is difficult enough in 2D, but it becomes almost impossible when you are dealing with a design that moves, like a packaging machine, or a piece of automation equipment. There is virtually an infinite number of possibilities for a collision to occur in designs that move. In 2D there is really no practical way to check for a collision. Fortunately, SolidWorks has a solution for collisions also. In SolidWorks you can move your design through its full range of motion while continuously checking for collisions between parts.
When a collision is detected, the motion will automatically stop and the interference will be highlighted. SolidWorks even provides an audible sound to let you know when parts interfere. If you make designs with internal moving components, Collision Detection is an invaluable tool to check the function of your design.
Interferences also result from tolerance problems. SolidWorks provides the ability to automatically check maximum and minimum tolerance so you can ensure the tolerances you are applying to your parts are appropriate. It even identifies which tolerances are the largest contributors to the tolerance stack-up problem, thereby saving you time in trying to figure out which tolerances to tighten, or which dimensioning schemes to change. When fit and function errors go down, efficiency goes up, and you reduce time, labor, and material costs.
