SketchyPhysics 3.5.6 (26 January 2015)

deskpilot

Sorry to bother you again Anton but try as I might, I'm still not getting SP to work. All looks good when I view my files. All sub folder appear to be there but in SU, there's no sign off it.
Is this correct?
C:\Program Files (x86)\SketchUp\SketchUp 2014\Plugins\SketchyPhysics3
In the SP3 folders, there's every thing I would expect.
Where else should there be folders or files that I can check?
BTW, I completely uninstalled/deleted everything and started again with a fresh download.

Ah, I see your problem. SketchUp 2014 has its plugins folder in different location. SU2014 and above have their plugins folder in AppData, while prior version have their plugins folder in Program Files. Delete the plugins folder you created in C:\Program Files (x86)\SketchUp\SketchUp 2014, and use the correct path, C:\Users\YOUR_NAME\AppData\Roaming\SketchUp\SketchUp 2014\SketchUp\Plugins.
The easy way to get to AppData is to write and send %appdata% in your windows explorer address bar, and from there you could navigate to your plugins folder.

The final path should look like this:
*C:\Users\YOUR_NAME\AppData\Roaming\SketchUp\SketchUp 2014\SketchUp\Plugins*

SketchyPhysics3
SketchyPhysics.rb

I'd suggest you to erase all the prior sketchy physics version if you installed any. You don't need them to get the latest version working.

Here is the similar post to consider if I didn't make it clear: http://sketchucation.com/forums/viewtopic.php?f=61%26amp;t=59782#p544700

Hope you can get it working, I will add installation instructions to the main post.

I shared emails with Chris the other day and he and I both agree its time to get the original source code for the libraries out into the community. (Chris really did all the work and created SP, I just did the port to OS X).

Despite our best intentions, we will never pick up the threads and get SP going as fast as Anton and you (the rest of the passionate SP community) are doing.

What is the preferred method you'd like for getting the source code into the hands of the community?

For those that are confused by this - I'm not talking about the Ruby code. I'm referring to the C code in the extension libraries that hook the SP ruby code into the Newton physics library and other assorted Ruby C Extensions that access OS specific functionality and other libraries (like SDL, Midi support, etc...).

Thankyou very much Anton, it's all there now. I'll play with it a bit later (only just got up). As you been discussing, this needs to put out there for the wider community.

Very well!

I think GitHub is the best way to share source to the community.

Is there a way to make control panel pop up elsewhere than in the middle of the screen?

Could you look at changing the opening state of the toolbars.
If you have it loaded they will always open on startup whether you closed them last time or not.

@Gilles Might be different on the Mac, but I moved it aside and it now always opens where I moved it.

This does not work on my mac

Any Idea when a Sketchup 2015 X64 Sketchyphysics version will be available?

Anton_S

It won't be available until people owning C++ source of SketchyPhysics decide to release 64bit compatible libraries that are used by SketchyPhysics.

TANER TAN

Hello! Very useful plugin! We expect the SketchUp 2015 64-bit compatible version. Thanks.

Please excuse me, if I did not lern my English very well.

SketchyPhysics gives wings.

Above is my sample file. My question is: How can I stabilize the joints so that they don't tremble so strong?

Maybe someone can set the parameters in the pattern file or give little hints.

Many greetings

It says I'm not authorized to download the file. Looks like you have to upload the attachment the other way, in the Upload attachment tab when you post a reply.

Meanwhile, to reduce joint flexibility, both bodies the parent and child have to have an identical mass. That is easy to set.

Select parent body, open control panel, and enable the scripted checkbox.
In the scripted field write,

onStart {
  this.setMass(1.0)
}

Do same for the child body.

You can change the 1.0 to any desired value. As long the values of parent and child bodies are not way off, the joint should remain strong.

Here is the video demonstration:

Move timestep to 1:20 for visual instruction on how to set identical mass.

According to Newton Dynamics, it's impossible to make newton joints 100% stiff. So, your model might end up in such situation. However, you can increase joint damp parameter to 100. It will reduce angular speed.
Here is the fixed model:
Verschraenkt.skp
Edit: Sorry, I had to edit this like 5 times.

Anton_S

No problem
Your right, you only had to increase damp of the servo joint.

Dear Anton, thank you very much. I did try to increase damp, but not only at first joint with slider, but also the three joints more without slider.
Your file is only first joint with damp 100. And it runs well.

Thank you, that I could learn much.

SketchUp and SketchyPhysics are wonderfull tools!

In my model the parts are like in real life in millimeters. For example 11 x 100 x 2 mm.
When I create the Physics joints, they are too big. They cover the view to the model.

In this case I have 4 joints. The distance between two joints are about 18 millimeters.

How can I adjust the size of Physics joints proper?

Model in Millimeter, Physics Joints become too big

Box

They are components, so you can just scale them as normal.
Use the corner handle and crtl to scale around center.
You can type in a percentage or size if you want.
And you can turn them on and off using layers, sometimes it's handy to have them big so you can see what you are doing.

Oh, thank you, I was missing the ctrl. key.

I am using SU2014 on a MAC
How do I install SketchyPhysics?
Downloaded it, went to preferences/extensions..... but cannot install.

Seems like other have had this issue but i couldn't find an answer for MAC.
Tried SU2013 as well but same problem.Please help!

Thanks
