This set of examples shows you how to create parameterized parts for Simscape Multibody and example MATLAB scripts for defining general extrusions. The parts have been used in a wide range of examples to show how these blocks enable you to rapidly model mechanisms. Within the library are a set of gear assemblies. The parameterized gear assemblies group the required blocks together and parameterize them so that frames are always positioned and oriented correctly.

Please read the README.txt file to get started.

Thanks Daniel. I considered adding the number of points as an optional parameter for Extr_Data_Ring. I decided to keep the list of parameters as short as possible, and hopefully the code is clear enough for people to extend it. Now that I have seen that this is necessary for some use cases, I'll consider adding it for all Extr_Data_* scripts that include arcs. Thanks for the feedback.

Steve, I mostly use the Contact Forces Library, but I noticed that the ring extrusion script is used here. Anyway, the visualization of the ring extrusion is clocked every degree which is probably okay in many cases, but I found the need to have the visualization of rings have more refinement. I've gone in and modified the Extr_Data_Ring script to divide the arc into 1000 divisions so it works for me, but I thought I'd throw it out there as a suggestion to refine the angular spacing of rings. (BTW, I've also noticed that visualizations of solid bodies using the Simscape Multibody "Solid" block are similarly coarse.)

Hi Steve,
I'm a bit new to Simulink, how do I get your excellent libraries to get into the standard simulink Library browser?

Thanks!
