CAD APPS is a set of Computer Aided Design (CAD) and Exploration Applications (APPS) that were developed for undergraduate Mechanical and Aerospace Engineering (MAE) students. The CAP APPS solve problems that are typically found in MAE courses. The CAD APPS have also been found to be useful to high school students, graduate students, and others.

you are the best larry , thank you so much for codes about truss.
please more video to show steps.


Will, thanks for sharing this great tool. When can we expect to see the updated version?


Thank you for your bug report! That bug has been fixed in the next version.
Moments cannot be applied in Truss mode (I assume that's what you were trying to do when you couldn't input a moment), the option will be hidden in the next version when you can't use it (instead of being grayed out).


It appears there is a bug when using imperial units. The conversion from lb-in to lb-ft seems to be incorrect. If I apply a moment and run the simulation, the value of the moment shows up incorrectly in the results window.



Great application, one thing though. Why is the applying a moment disabled?

A GREAT MATLAB app to design, solve, and visualize structure and truss problems!
