Full article describing this challenge:


Hello SOLIDWORKS Power-Users and welcome to the 7th WPUC!


Other than having fun solving riddles, the goal of this week's WPUC is the same as last week's: facilitate through brainstorming the finding of new techniques for the benefit of the SOLIDWORKS Community.


Hopefully we will:

  1. Identify areas where SOLIDWORKS' functionality needs enhancements
  2. Design workarounds to overcome the current lack of functionality
  3. Submit new ERs or promote existing ERs that are relevant to this WPUC topic.


During the first WPUC, we found out the need for boundary mates. What about volume mates? How can you limit a component's movement in a given volume, while preserving all other degrees of freedom? Let's think about that this week.


For eternal glory and 1000 points, provide the best solution to this problem:


  1. Watch this video: SOLIDWORKS 7th Weekly Power User Challenge (June 2nd, 2017): Simulate a Volume Mate - YouTube
  2. Download the attached files Prisoner.X_T and Jail.X_T
  3. Convert both to SOLIDWORKS format
  4. Start a new assembly
  5. Insert Jail in the assembly, fix it and make it virtual
  6. Insert Prisoner in the assembly and make it virtual
  7. Create a mating scheme that would keep the Prisoner confined in the Jail.
  8. The Prisoner can go anywhere inside the Jail
  9. Upload the final assembly (with virtual components, please) by replying to this message.



The first solution that meets these criteria would win 1000 points.


The first solution that would not use limit mates wins 1000 points.


The solution with the smallest number of mates wins 1000 points.


The best solution (my pick) would win 1000 points.


If the solution is out-of-this-world, the contestant will be awarded 2000 points and be proclaimed a SOLIDWORKS DEMIGOD.


Good luck!

In order to give as many power-users a chance to win, and considering that our friends from the US observe Memorial Day today (long weekend), we will wait for everyone to return to work before posting the problem.

So, bookmark this thread and keep an eye on it Tuesday morning (May, the 30th) Be the first with a great solution and you will become a WUPC winner.
