Hey Tom,
First step would be to export in .shapr format, and name it something like Full Backup.
Depending on what you want to keep from your designs, you have some choices.
- exporting in .shapr format keeps everything. Sketches, construction planes/axes, bodies, history, etc., even if they are hidden (by the “eye” icon or by isolation)
- exporting in x_t format keeps bodies, and only those that are not hidden.
If you just want to keep bodies, you can use isolation to get only the items you want in view then export as x_t.
If you want to keep sketches for each “sub-project” you’ll need to delete other sub-projects and their sketches then export as .shapr. Note: with current parametric version, when you delete a sketch, you also delete things dependent on that sketch. Then for the next “sub-project” use a copy of the Full Backup and repeat.
Final step is make a new project, import what you exported and make sure you have everything you want and it looks OK.
