I find it difficult and time-consuming to locate and select Contacts the way they are currently organized and displayed in the Simulation workspace. One must open the Contact Manager and select each contact individually to ascertain its location.
It would be great if Contacts could be viewed and edited in the Simulation workspace in a similar way to Joints in the Model workspace. I am not suggesting that they be made the same thing; indeed, there are times when I create Joints that I do not want to be present in a simulation. The current method of locating and editing Contacts, however, leaves something to be desired.
