This is a implementation of an engine for the OpenBimRL api. The framework includes functions for OpenBimRL parsing, execution and generating results. This project also containes a set of already predefined functions that can be used in OpenBimRL documents for defining precalculations and in extension perform rule checking.

Getting started

Requirements

Note: This engine is currently incorporating the Apstex IFC Framework and Viewer into the parsing and interpretation of the building model context. As a requirement, these has to be included in or replaced for this project to work.

Dependencies:

• Apstex IFC-Framework + Viewer
• OpenBimRL-API

More dependencies are provided in the pom.xml and automatically included via maven.

Minimum Example

An example execution of this engine is provided in RunExample.java and can be used to perform rule checking out of the box. Results will be printed in the terminal. However, for a more simplistic approach this code provides an example:

File modelFile = Kernel.getApplicationController().openLoadFileDialog("IFC Model File", null);
IfcLoadManager.getInstance().loadFile(modelFile);

File ruleFile = Kernel.getApplicationController().openLoadFileDialog("OpenBimRL File", null);
ArrayList<File> openBimRLFiles = new ArrayList<File>();
openBimRLFiles.add(ruleFile);

new OpenBimRLReader(openBimRLFiles);

for(AbstractRuleDefinition ruleDef : RuleBase.getInstance().getRules()) {
	ruleDef.check(
		Kernel.getApplicationModelRoot().getNode(0)
	);
}
