    MBSE for MagicDraw

    Plugin for MagicDraw to support MBSE with SysML

    Support for more productive Model Based Systems Engineering, following the recommendations in the Cookbook of the INCOSE SE2 Challenge team http://mbse.gfse.de The Plugin for the MagicDraw modelling tool provides support for model based document generation which ties together system model and documents to keep them up to date and consistent, using a AWYSIWYG editor in MagicDraw. It provides basic support to model variants and extract variants from a system model. It provides support to generate organizational structures according to the SE2 Cookbook recommendations. It provides basic pattern based support to reason on a system model, for example to extract numbers like total power, cost, power consumption for a given product tree The MBSE plugin for MagicDraw requires MagicDraw 17.0 SP4 or higher with an installed SysML plugin 17.0 SP5 or higher. Installation instructions can be found in the file ReadMe.txt in the download area as well as the corresponding UMs.
