Air Volume

[dakeb]

What is the best way of calculating air volume in a complex 3d assembly?

In Creo I used to create a model of the air then using merge, subtract the models that intersected it.

Does Catia have a similar function?

this method seems correct to me

Yes, but instead of merging parts, in CATIA all can be modelled in one CATPart using Bodies and Boolean Operations (Adds, Removes and Intersects).

In Assembly workbench you can use Tools - Generate CATPart from CATProduct. This will do a single CATPart which will help you to go forward with your method.

Thanks for the replies, very useful and informative.

Problem I have is many of the parts are hollow, so subtracting the volume might not give me the actual air displacement.

Has anyone found a good way of getting Catia to only account for volumes bounded by external surface, in order to work out the displacement in a fluid?
