I am wondering if this function no longer works. I am running r2019b on OSX Mojave. I removed the _16b from the call to smexportonshape_16b. It seems to be running the version that installed with Matlab. What I get is a blank Matlab web browser screen. I changed the setting in Preferences so Matlab used the default web browser and what pops up is a window with a code from OnShape saying to copy the code and paste it in your application. I am guessing that OnShape changed how it authenticates, and this application needs to be updated. I have not searched to see if there is a fix yet.
Hi, When I create my model and try to assemble it I get an error that reads:
['WattLinkage2']: The following errors were found in the model WattLinkage2.
['WattLinkage2/Solver Configuration']: *** Model not assembled: position violation *** Resolve this issue in order to simulate the model.
Any ideas on how to fix this? I am running Matlab R2018b
K F: Make sure you have installed Simscape and Simscape Multibody. Both of these are required for export. It sounds like you do not have them installed. --Steve
Hi, I am getting a "Undefined function or variable 'pmsl_checklicense'." when trying to run this. Any ideas? I'm on R2016b.
