Hi rbarr,

I have made a number of changes to your model, but I think it now does what you you intended it to do. I have moved the the pivot point nearer the front of the desk, increased the height of the desk top and chamfered the front of the top, all to provide clearance to allow the top to raise to a reasonable angle. I have also added an extra pivot and hinge at the back with second slider. The back slider was trying to keep the top at right angles to itself while the front slider was trying to tilt the top and this is part of what was causing the problems. I also re-grouped some of the joints. The original hinge joint was not grouped with anything so that is why it would not move with the rest of the mechanism. Hope you like the result and let me know if you need any more help.

Kev.

WOW! You have gone above and beyond my expectations in helping me out here. What you did is near perfect to what I wanted it to do. All I have to do now is to make a couple more tweaks to get the desired angle of the desktop.

I also am going to take some time to reverse engineer what you did as well to make sure I can can do it on my own next time.

THANKS!

I am trying to simulate a raising monitor for a project I am working on and sketchy physics has been a great help in testing my geometry.

My current model still needs help and I cant quite figure out how to do some things to make it work "properly". In my model there is a rod that slides along a slotted path. As the rod slides, the back of the top panel raises. However, my top panel does not stay constrained to the slot where the is supposed to slide.....does that make any sense? Is there a better way to do what I have done?
