3. www.ddss.arch.tue.nl Challenge Automation of the planning process. Advantages: Independency from the planner Quick first concept plan

4. www.ddss.arch.tue.nl Implementation

5. www.ddss.arch.tue.nl Construction algoritms Analysis by object name: Walls are bearing floors, colums are bearing beams, etc.

6. www.ddss.arch.tue.nl Construction algorithms Analysis by object elevation: Object with a lower elevation is bearing an object with a higher elevation

7. www.ddss.arch.tue.nl Construction algorithms Analysis by directed graph: Each object is a node in a connection graph.
