Hi All,
MSPhysics works well for me !
For that, you must put the MSPhysics directory and MSphysic.rb directly in the library directory of SKetchup 2019. Futhermore, you must add AMS_library 3.5.0 + with the extension manager.
if you have any difficulties, ask to me and i answer you
Best regard

Hi Thierry,
Do we need to install first the library? or it doesn't matter the order of installation.
Thanks in advance,
Jose Castellot
