When an Integrated Development Environment (IDE) is developed; the support for multiple views of the same document is often essential. An example of this is Modelica models; as it should be possible to view and edit the same model in both its textual and graphical representation.

One implementation of Modelica is the open-source platform JModelica.org. It contains the JModelica.org IDE; that provides a text editor for Modelica code; based on the Eclipse platform.

In this paper; we present an implementation of a graphical editor for the JModelica.org IDE. Several challenges with implementing a graphical editor for Modelica are discussed. Among others; the difficulties in rendering Modelica diagrams and how to interact with existing frameworks in Eclipse are brought up. A method for preserving the formatting of a modified source code file is also presented; which is essential when the model is altered in the graphical editor.

The presented implementation is compared to other open source software (OSS) implementations of Modelica editors.
