This file contains a scissor lift model with hydraulic actuation built using Simscape Multibody and Simscape Fluids. The scissor lift model is assembled from a library of parameterized component models. Intermediate models are included to show you the steps of modeling this system. A MATLAB UI is also included that allows you to interactively change the dimensions of the scissor lift.

Please read the README.txt file to get started.

Hello, when I downloaded and installed the files to my desktop. When I opened Scissor_Lift_Simscape_Multibody/Scissor_Lift_Simscape_Multibody/Scissor_Lift_R16a/Libraries/Scissor_Parts_Lib.slx on Mac, the library was opened but all the icons associated with the 10 blocks are missing. Instead, I got ??? on each block and 11 warnings listed below. Anybody knows what to do?

Steve, why you use 10 for link density in the param file?
