This screenshot shows an assembly resulting from another particularly complex sequence of operations, the model shown was the test case provided by Sener. Their assembly process involved fitting a set of clamps onto the large semi-transparent blue housing, the darker blue box was then positioned onto the clamps and fitted. Finally a selection of pipes were fitted onto the box.

This test case was very interesting in the sense that it highlighted a particular problem with the model. One of the pipes which needed to be fitted to the dark blue box, could not be positioned directly due to an obstruction caused by a feature of the box itself. The only way to position the pipe onto the box was to slide part of it under the obstruction and then assemble it onto the box. However, the pipe also had a valve which needed to be fixed onto it before it was positioned. This valve was too large to slide under the obstruction and so the part was actually impossible to fit....as proven by Divipro!

A movie showing part of the assembly of this test case can be downloaded either as a mpeg (31Mb) or a divx (11Mb) file, the sequence shows three connectors (each attached to flexible pipes) being assembled using constraints onto connection points on the dark blue box. Subsequently a rigid pipe is assembled onto its connection point and finally one of the flexible pipes is wrapped around the box.
