The 7th Weekly Power-User Challenge (June 2nd, 2017): Simulate a Volume Mate (Prisoner in Jail)

time to research!

Alin,

The additional solution with the "helper" component is completely trivial.  Basically the empty "helper" component would have the exact same mates as the prisoner has now.  Then the prisoner component would have a origin-origin coincident mate to the helper.

Sorry... No can do. I only have 2017. 

"One little glitch, though. For some reasons, in the first configuration, when you drag in 3D, the sphere can jump to the alternate solution:"
That's why I needed to add the other part and mate (making the other configuration)

Here Is the updated version 2

If hes a nice relaxed prisoner he will stay in.

But when he gets angry he can break out.

plane madness

Dan, I know this is important to you...

But...

Why not add the SW Last Saved With column to Windows Explorer?

Works like a charm.

I save as the files from this Forum to a Temp folder, Open Windows Explorer (and leave it open all day) and after extracting files from ZIP I look before opening.

Peace Brother.

 

That is awesome!  I didn't even know that this existed.   Thanks Rick.

OK, fixed.

Roland Schwarz Excuse me for cheating and using your own solution

P.S. Don't worry about your buddy I do treat him nicely and he is even happier now

Alin Vargatu You gave the idea to get rid of one component and get them only to three mates now they are just two but with cheating again (as long as no one rotates the hidden component and we just move the prisoner we are good)

SW version 2017

Alin,

Plus it doesn't quite go into the corners as there are very small fillets in the corners of the surface but Roland Schwarz's solution is brilliant as you said. This was how I started trying to find a solution, Pin in Slot method, to the problem but it wasn't as elegant as Roland Schwarz's & kept breaking out & rolling down the road, a rebuild would bring him back . I used the freeform tool to create a single surface, not very elegant again, maybe someone can improve on it.

Roland Schwarz's example is the smoothest to move around in all axis of movement, you can really throw that prisoner around his cell.

I could remove the fixed "XY" component, but it's purpose is to associate the shape of the XY domain w.r.t. the cell. I do this first with a fixed version so that the shape does not need to regenerate when the floating version of the XY domain is moved.

This is a technique I developed for designing hinges.

Similarly, constraining the Z movement to a spline is something I learned working with linear actuators. Its a useful way to limit movement within a sketch.

Funny you should say that. I'm always telling people NOT to think outside the box. First, get to know the box. Where is it? How big is it? What is inside the box that can be used?

Like a toolbox, what you need is more likely in the bottom corner than the top tray.

Think inside the box!!!

ONE and TWO

Here is one thought....

Set up a Online Voting Poll for the people here on the forum to Vote one time only for their pick of the Top Ten - The contestants would be whoever has won any of the Challenges within that season which would run a calendar year starting January 1st..

Here is where your credibility with SolidWorks Corporate would come into play, I would push for the Top Five getting a free trip to SolidWorks World and the Bottom Five having some kind of nice plaque in recognition for making a difference in the community.

This would put you and all the VAR's in a neutral position and the people that can apply the awesome challenges to their daily work, will be the ones making the decisions sending the top five.

And.... You Alin Vargatu will do the honors at the SWW - and oh - I'll take chocolate milk please..

If I remember correctly the beer is free at SWW and the fact that I'm having trouble remembering probably means it is. Now,,, a means to get there for free would be great incentive to put up with the frustration of trying to figure this stuff out. I'll bet that these answers would be even more awesome if that is possible.

Hi John Stoltzfus;

I miss you guys as now I’m full time working with NX exploring other CAD possibilities, a target set by myself.

Time to time I check this forum to see if I could be helpful here or if I could learn something new relevant to me. Recently I saw one of the challenges of our friend Alin Vargatu and thought of replying.

Hi John,

I just saw this! In the Siemens NX site, I’ve been (mike_fdo) listed as an Top Expert too. Maybe I’ve done something correct.@

The difference between the model that Roland Schwarz uploaded and what Michael Fernando just taught us is

Roland's example can be applied to an assembly that is connected to a linkage and the little ball will remain in the box, where Michael's example is only held in place with Physical Dynamics and couldn't be used in the same assembly.. It is great to know though..

"Winning" this challenge with physical dynamics would be like a rugby player "scoring" by carrying a soccer ball into the goal.

Using Physical Dynamics is also somewhat slow - I brought this up in the 1st WPUC for the Pin in Slot

It used to be in the Assembly Modeling Class that VARs taught, but I don't think they still cover it.

I'll have to dig through some of my old drives to see if I can find the class files - There was a Geneva Wheel, Bevel Gears, and some other cool stuff.

I remember teaching it at the VAR, but I'm not sure when it was dropped, I left the VAR in late 2010.
