Thanks Anton, that did produce an error, though I don't understand it.
Here is what it gave me:

Thanks for looking at this!

Never mind.... It was idiot error! I had installed it through Sketucation AND through the Ext Warehouse and that was causing the problem.

Thanks again!

Still dead on my end. It's like it partially locks up. Once I click the play button it starts acting weird. When I try to push things around all it does is try and draw a selection box.

Here is the sample of one. I tried it on others and got the same result. Sometimes it also disables my keyboard shortcuts.

Thanks for checking it out!

MS Physics Sample.skp

Hi All,

I just installed MS Physics from the Extension Warehouse and when I run the simulation nothing happens. The only thing that does happen is the right click context menu stops working. I tried this with two cubes hinged. Any suggestions? This is running on Sketchup 2016 Win10 64.

Thanks!

Also forgot to mention starting a new file from the current Sketchup session does not fix it. I have to actually close it and restart Sketchup.

That would be awesome Fredo! I use it every day, Thanks!

Thanks so much! Now I see what you were saying about ThruPaint. This will help model performance greatly!

Thanks again for all your input!

That is amazing! Thank you so much for that! I find it interesting that when I selected everything and changed the default material in the Entity Info window and saved no change. But when I select everything and use the paint bucket and save... then I get the file size reduction.

Really appreciate all your help!
Thanks!

Thanks! I will check it out.

Thank you! How did you know that? That is very interesting!
I just ran through paint on it, setting it to paint the default material an all connected faces and it dropped the file size by 3mb. Also ran "Clean All" from the Twilight menu but no change in file size. Thanks for checking it out!

The smaller one was what I was using in my main model of the house(there are over 100), the bigger one is what I modified for 3d printing. I mostly wanted to use it to avoid any future confusion. For now though I think that's all I can do.

Thanks!
