Tutorial Proof of Concept - SketchyPhysics Alternative

Since my sketches were drawn up in SU 2017 64bit, I didn't feel like redoing things in an older 32bit version to get SketchyPhysics running. So what I have here is a proof of concept for using SimTools with MSPhysics which the author picked up where SketchyPhysics stopped and runs an updated physics model. This PoC is for a 2dof motion sim

Procedure is similar to the SketchyPhysics guides but still different. Simple sketch with two servo motors is set up as an example included in the zip below.

1. Place simtools.rb into your Plugins folder for SU (location varies but recent versions are in your AppData/Roaming folder under SketchUp)
2. Load up your copy of SU
3. Search in the Extensions warehouse for AMS Library and MSPhysics
4. Install both (disable SketchyPhysics just to keep the UI clean)
5. Open up the servos.skp sketch
6. Open MSPhysics UI and select each joint (orange circular arrows)
7. Verify min / max are 0 to 180
8. Verify controller has correct variable; left joint = $axis1 / right joint = $axis2
9. Import the Axis and Interface presets into GameEngine
10. Run game or Output Test in GameEngine

This gets the ball rolling. A better sketch will be uploaded that will be a proper 2dof motion sim. Stay tuned.

Very Impressive and I need full details please ...

Working on a full walkthrough like the current FAQ guides. Plus a full featured model.

Okay put together a better connection script since I was having latency issues with no understandable reason. I haven't had any issues yet with this new script. Includes proper maths now too.

I Also updated the sketch and the joints to do 0 - 180 degrees so the servo arms will be at their zero positions and will flatten out when Game Engine connects.

Has this been developed further? I've been having difficulty in getting it to work in Sketchup 2017.
Looks like the ruby script isn't connecting to Sketchup. I assume the simtools.rb file just goes in the C:\Users\myuser\AppData\Roaming\SketchUp\SketchUp 2017\SketchUp\Plugins folder?
Does Sketchup have the required ruby script socket.so? I'm confused!

I did it!

If anyone else is struggling you'll need the socket.so file I've included in this zip file.
I added a line in simtools.rb that spits out the axis too so you can check you're connecting to simtools.

Now to build my platform!

Just to add you need to ensure the MSPhysics joints are labeled as $Axis1a and $Axis2a in the model.

Hi. I can not get the data sent by Simtools to appear in the Ruby console. There only appears the MSPhysics Simulation Results.
I get this error when I start SketchUp

Any idea of how to solve it?
