Help with hinges

[cholme]

First I will say I love the idea of Sketchy Physics. I am a furniture maker and frequently set out to use SP for my designs but quickly get discouraged because I can't predict the results and thus I don't use it.

I am currently trying to design a piece with what is like a bifold door. So I need to have doors that move with hinges for the other doors. When I create a group and connect the hinges the doors swing but don't move from their position. When I group the door with the hinges they work properly EXCEPT the two doors swing through each other. I saw a video on another thread which seems to have a work around but creating a flat group and including it in the hinge group but for some reason that doesn't work for me.

This seems like a powerful tool but man is it difficult to use.

So, 2 questions.

1. Any suggestions for my specific hinge problem?
2. Any suggestions for truly understanding Sketchy Physics? Videos, Manual, anything?

Thanks,

Chris

Hi Chris,

Dynamic Components are pretty good at simple animations such as furniture might have. It's for SU pro, though.

I would also recommend KeyFrame - it's not free, but is worth its reasonable price.

One limitation of SketchyPhysics is that objects that are below a certain size will not move. If your individual door panels are very thin, for instance, they will not move. If you connect several thin panels together with joints, then group them all into a single group, that group will be large enough to move in the SketchyPhysics environment, but the panels themselves will be frozen relative to each other.

Sometimes, you need to scale everything up to make a simulation work, even though your dimensions will be proportionately larger than in real life.
