PartBody versus Bodies


The CATpart file always includes a PartBody. It is there from the start and can not be deleted. The PartBody is a body, which is used as a container for a solid. In this sense the PartBody is identical to the other Bodies, which have been created with Insert > Body.


Meshing in PartBody

However the PartBody has a distinguishing mark. If the CATPart is going to be meshed due to a FEM computation, the program will automatically use the the solid in the PartBody. Therefore if you want to use a simplified solid geometry (A) for the meshing, the corresponding solid has to be placed in the PartBody.



Change PartBody

If you have designed the wrong geometry in the PartBody  it is easy to correct. Select the body you want to use as PartBody and then the context menu Body.# object > Change Part Body. The selected body will be changed into PartBody and the original one will transformed into a plain body. The PartBody will also be placed at the top of the bodies in the tree.
