There are several ways to install plugins in 2014, which one did you choose?

May I jump in on this thread gents. I've recently purchased a new pc,loaded SU2014Make and SP3.5.5.. Kept getting that annoying warning about a bad install so I went back a step and loaded an earlier version, 3.1. Now, full install seems OK but the plugin is permanently disabled. Try as I might, I can't get it to do anything but say it will be disabled next time I fire up my pc. Any answers please. If I have to go into DOS or similar, please explain all steps.

Hello,
It would be nice if you provide me some more details.
  • What warning message do you get?
  • What operating system are you using?
Regardless of that, I don't think SketchyPhysics 3.1 will work in SU2013 or above. Keeping it in the 2014 plugins folder is useless. I suggest you to go to C:\Users\YOUR_NAME\AppData\Roaming\SketchUp\SketchUp 2014\SketchUp\Plugins, and erase all sketchy physics versions from the folder. Then, download the SP3.5.5 if you hanven't so, and extract content into the plugins folder. It should look like this:
...\Plugins\
  • SketchyPhysics3
  • SketchyPhysics.rb

Hope this helps or provide some details if you can't get it working.

OK, done as you suggested but now I'm back to:
Loading error
Error Loading File sketchyphysics.rb

That file is from old sketchyphysics version. It seems you didn't delete sketchyphysics.rb from the plugins folder as i suggested in previous post.

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: viewtopic.php?f=61&t=59782#p544700

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

Offer to get SP library source code released

Postby willeykj » Sat Nov 15, 2014 3:17 pm

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.

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.

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

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.
  1. Select parent body, open control panel, and enable the scripted checkbox.
  2. In the scripted field write,
    Code: Select all
    onStart {
      this.setMass(1.0)
    }
  3. 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:

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!

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

Physics Joints too big

Postby N Lindenthal » Sun Dec 21, 2014 12:24 pm

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?

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.

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!

Hello, I installed Sketchy Physics via the auto-install into 2013 version SU. Problem I am having is when clicking the play button, SU crashes. I have removed the Sketchy Physics from the plugin folder application support/sketchup/plugins and re-downloaded the plugin. It still crashes when clicking the play button. Appreciate some help on this. I can provide the "crash report" that appears which offers an option to be forwarded on to APPLE (as if they really care) LOL.
Thanks

Greetings & Happy New Year,
I have installed Sketchy Physics via the auto install feature and there was no problem. Opened SU 2013 and the tools were there. My problem is that upon clicking the play button, briefly the control panel appears,then SU crashes.Has anyone else had this issue? I can provide the crash log that appear on the screen if that would help.

Thanks

I wiped and re-installed my Mac software, primarily on the basis that I wanted to run Sketchup with this plugin so I was gutted to find it does not work with Sketchup 2015 (I just found the comment hidden away that it does not work with 2015 64bit which I assume is the issue!).

How serious is the problem? Can you give an idea of how big a problem it is (just in case I can help to fix some problems myself) or a timescale if you are planning on fixing it yourself?

Ruby is not my main skill, but I would give it a go if you were to give me some direction as to the problems?
