The Compress Shells command is used to convert shell entities to a compressed representation. Compressing shells significantly reduces memory consumption while running Fidelity Pointwise. Shell compression also reduces the file size and loading time of saved project files.
Note: Some operations (such as Split, Join, Extract, and Orient) require compressed shells to be temporarily expanded, which will consume additional memory. If you need to perform these types of operations on your shell entities, it is recommended to import the shells as expanded (i.e. with Compress unchecked), make your modifications, and then manually compress the shells using the Compress Shells command.
