Thanks of a lot for your efforts !
I can't wait to be able to use this wonderful plugin again sometime soon
(unfortunately I can't be of any help, not knowing anything about programming... sorry)

The purpose of all this is being able to "play" with such a model in sketchyphysics (collapse, explode, etc...)
I think (am I right ?) that it has to be separate groups in order to do so...
If the groups interpenetrate, the sketchyphysics contextual menu or dialog box will not unfreeze the groups. Do you think it's true ? Or am I making a problem where there is not ?
Thanks again for your patience

Hello Tig,
thanks for your answer.
The problem is I have 6500 groups on that model !
(http://sketchup.google.com/3dwarehouse/details?mid=d34e5f52b8698e0e72879169b6bea9fb&prevstart=0)
I couldn't treat them individually...
Do you think there is an automated way to do it ?

On the image below, I used Ky,'s Group and Pushpull 2d faces to extrude a few faces as groups. But the groups interpenetrate, which is unsuitable for sketchyphysics (this is my guess, but I could be wrong —I discovered all these great plugins you guys make just a few days ago...)
I could use the SU feature Solid Tools >Trim, that would do the trick, but this tool seems to apply only on two solids, which is not enough... (again, I could be wrong on that point...)

On the other image I used Joint Push Pull

Would you have any more idea ?
Many thanks

Dear Fredo,
Thank you for your answer, and congratulations for the great job you do with all these plugins.
I tried what you suggest, but as a result I have one group, and I would like to have 5 different groups / solids>

Joint is an image of what I get.

Can you think of a way to do it ?

Hello,
I'm trying to extrude a multitude of faces with the same kind of behavior than the jointpushpull plugin. My concern is that I need as many solids than faces as a result.
If I jointpushpull 5 adjacent faces, they will end in a single extruded group. What I would like is having 5 adjacent solids as a result.

The ky Group PushPull 2D Faces plugin does that very well... it found out to be the best solution for me make in making that sketchyphysics video : http://youtu.be/v9jWE1aoueA

BUT for this video the faces were all parallel. What I didn't find yet is a way to obtain the same result (multiple adjacent solids) when the faces are NOT parallel. The ky Group PushPull 2D Faces plugin actually does it, but the groups all interpenetrate, which does not end with solids, which is not ok with sketchyphysics...

My point is I would like to extrude this wonderful head model by 3D creator (http://sketchup.google.com/3dwarehouse/details?mid=d34e5f52b8698e0e72879169b6bea9fb&prevstart=0) into multiple solids, then use it in sketchyphysics (if my iMac accepts to deal with sio many entities...)

Any idea ?
Many thanks

Hello Oxer, many thanks
I tried to find the 3.1 version, but it doesn't seem to be available for download anymore (on this page : http://code.google.com/p/sketchyphysics/downloads/list)
Do you know of another place to find it ?
Thank again for your answer

Hello,
congratulations for this marvellous job !
I'm using sketchup 8 on a Mac Book Pro running on Mac Os 10.5.8
and I would loooove to be able to use sketchyphysics with this computer
any chance ?
thx again
