I have an assembly of a mold (of a bottle) done using a cavity, split into parts, then many features added to each part of the mold. Accessory parts & fasteners added to assembly, etc.
Need to create a similar mold assembly, wherein a new cavity shape, mold block size changes, water-line changes, will be needed. Most parts will need to change, but I would like to just change them without making them all over again.
What approaches do you suggest?
If I "save-as" the top level drawing or assembly, how do all the linked parts get duplicated so I can change their filenames prior to making actual changes to the models, protecting the original assembly from any changes?
And can I replace the cavity shape by substituting a new bottle part file?
