SketchyPhysics3 FAQ.

Sgal

Use of the joints 2
Other thpes of joints

Corkscrew: Object linked to this joint can spin around his axe and move between maximum and minimum.
Spring: Object linked to this joint can move linearily along his axe. The spring joint will try to bring back them to the first position.
Ball: Object linked to this joint can rotate freely around the joint. The object axe points to the joint.
Universal: Object linked to this joint can rotate almost freely around the joint. Unlike the Ball one, the Universal joint won't allow the object to rotate around his axe. See those images (I found them in an old post of CPhillips) to understand the concept:

Thanks to =Physicsguy= for the correction.
I think that an "official" SP manual is a primary need. This plug-in is growing too complex for an immediate comprension for a new user. Maybe a Wiki...

CPhillips

Cleaned up the thread a bit. Yeah the faq is getting sort of long. Maybe it should be moved to the new Wiki.

[*]How do I make a simple objects

You can make simple objects using the SketchySolids toolbar as you will se in Flash file.

Now that you have installed SketchUp, use the following link to view the latest SketchyPhysics downloads...

Again, run it, and follow the on screen prompts. It will install itself in the SketchUp Plugins folder.

This is just for windows, right? Because SketchyPhysics never installed itself on my mac. I finally figured it out, but some more info on how to install would be appreciated. For mac users that are reading this: Put the downloaded, extracted files in this folder: username/Library/Application Support/Google Sketchup 7/Sketchup/plugins.

I had to create the plugins folder because it wasn't there. Then I got another bug, "Error Loading File SketchyPhysics.rb
undefined method `file_loaded?' for main:Object"

I found many references to this bug, but no answers, until I found this tip from fernandogalin on the issues page (http://code.google.com/p/sketchyphysics/issues/detail?id=9

copy sketchup.rb from Tools folder to Plugins folder
edit sketchyphysics.rb from Plugins folder and add this line at the begining of the
file: load "sketchup.rb"

This solved my problem and now I can use SketchyPhysics, which I love! This is the awesomest plugin ever. Hopefully this info will save some others from going through the same confusion that I did, so they can get to the good part.

Mmmh, not sure if this thread is still active.
BTW, I'd like to share my 2 cents work with the community, I "updated" the Quick Reference Card (mostly for togethearth MAC users at first):

If other Mac users find it useful let me know.

Is there a plugin for SketchUp that computes electrical systems voltage, current, resistance? Or maybe a more complex plugin that accepts more variables?

Hi all

great stuff pls keep it up. I will try to add my 2 cents as i progress
I cant post any links or skp models to demo my points, this is very limiting

Hi Chris. I need to get back into SP again.
I "left" only because I found the learning curve got too steep too soon, but now I am determined to get it to work.

BUT.....

"Now that you have installed SketchUp, use the following link to view the latest SketchyPhysics downloads...
http://code.google.com/p/sketchyphysics2/downloads/list?can=1&q=&sort=-uploaded&colspec=Filename Summary Uploaded Size DownloadCount"

And which file(s) would that be????? I would have expected the latest file(s) to be, and remain, at the top of the list, but it is buried down and I am confused as to which one(s) I need (Win XP) to get going.

@sgal said:

I believe you mean "axle", not "axe"?

jgb

Still no answer on which file(s) is the latest release.
I went to the Download page and noticed a few things that make no sense; to me, anyhow.

What is a Deprecated file??

Why is the release level not fully defined in the file name?
3.x is meaningless.

Why is the "Release Date" column blank?

Why are the file descriptions/summaries so terse and literally non-informative?

I sorta expected better than this based on the quality of SP in general and the high level of user support Chris and users deliver.

ahnvtk

Even with these helps I'm still having a very hard time identifying the newest SketchyPhysics download. Is it SetupSketchyPhysics3x-Apr2.exe @ this page?

Dying for SketchyPhysics IV. Seeing small SketchyPhysics solids fall through the floor in the version I have installed now
