Obtaining and installing my SysMLHelperProfile

In some of my videos I've hinted at a method for speeding up the use of Rational Rhapsody for systems engineering tasks such as creating requirements from use case steps and creating executable MBSE models from textual use case models expressed using activity diagrams.

This method acceleration is achieved using a plugin I've written called the SysMLHelperProfile that adds new menu commands to the Rhapsody menu. It provides a similar function to that of the SE-Toolkit provided by Rhapsody to support the Harmony/SE, except that I've made this helper available as an open source project on GitHub under GNU General Public License (GPL) v3.0 terms. The latest improvements were to improve the double-click functionality to easy navigation graphical.

This video gives instructions on how to install the SysMLHelperProfile. The helper itself is a work in progress:

Installing Rhapsody with Cygwin/gcc for Executable MBSE

If you don't install Rational Rhapsody in the right way then you might be missing out on a lot of its capabilities. If you want to try using Rhapsody's powerful simulation capabilities for Executable MBSE then it's more important than ever to get it installed right.

These are the instructions that I provide for setting up Rhapsody with the Cygwin gcc compiler for my Mastering MBSE with OMG SysML and IBM Rational Rhapsody and Executable MBSE training and consulting. The main thing to consider is that you can save an awfully large amount of disk space and time by just installing the small part of the compiler tool chain you need.

The training uses the Rhapsody Designer for Systems Engineers Edition. However, as the slides suggest we can pretty much install all the Editions and then control the Editions we use using shortcuts.

Rhapsody Tip #17 - Making space on sequence diagrams using the Shift key (Simple)

And so the foraging for useful tips and tricks continues. This simple tip can be used to speed up drawing sequence diagrams in IBM Rational Rhapsody. If you don't hold the SHIFT key before you click on an element then just the individual element will be moved. However, if you hold down the SHIFT key before selecting an element on the diagram then Rhapsody will move all the elements below to create or remove white space. The technique can also be used to create or remove white space between lifelines on the diagram as this very short video highlights ...

Rhapsody Tip #16 - Some magic drawing key tips to know (Simple)

IBM Rational Rhapsody has a number of handy key presses you can use when you're drawing diagrams, e.g., holding down the alt key to prevent re-sizing contained elements is the one most people learn first but there are others, e.g., press Shift while re-sizing will keep the shape's symmetry, and pressing Shift while moving an element with arrows allows you to nudge without moving the contained elements. There's also ways to add user points and draw lines parallel to the axis. This short video shows a bunch of them.
