  • the inventive method comprises the following steps: a) assignment of an installation location for each object, b) execution of an area search around each object for the determination of neighboring objects, c) creation of a first data set containing the adjacent objects for each object, d) providing a second data set destined for each object type contains questions about possible interactions with other object types, e) linking the first and second data sets such that a question list is created for each object containing questions from the second data set for those objects or object pairings that are adjacent in the first data set to be expelled.
  • An installation space is a spatially defined area in which a plurality of objects should or must be arranged.
  • an installation space is preferably a defined space, in particular an interior, a means of transport, more preferably an aircraft.
  • objects designates components or assemblies that are to be arranged in this installation space.

  • a commercially available CAD program that can perform such Clash analysis is in ⁇ play as the CAD program CATIA (Computer Aided Three- Dimensional Interactive Application) from Dassault
  • the second record is a collection of questions about possible interactions between object types.

Conversely, it is ensured that no superfluous questions about possible interactions have to be asked and checked, since only with a positive radius search (first data record) and basically possible interaction of two object types (second data set) a question for the list of questions or a hedging order is generated.

If the corresponding enlarged ⁇ bounding boxes in the context search or clash analysis have overlapping coordinate ranges, the corresponding objects are identified as adjacent in the sense of the feature b) of claim 1. Due to the described enlargement of the bounding box, it is achieved that even objects with a defined maximum distance from one another are still identified as being adjacent. This may be useful, since interactions between different object types that are to be tested may also arise if two objects are at a distance from each other.
  • Examples are for those to be tested Kaswirkun ⁇ gen even at a certain distance from the accessibility of maintenance openings pivoting doors or flaps or the like are.
