Best practices to reduce file size :
- Purge models. Delete unused groups.
- Avoid exploding geometry
- Minimize the use of In-place families
- Minimize the use of void forms
- Use families rather than groups
- Maintain fewer links
- Link only in appropriate view. For example, a detail should be referenced to a detail view
- Use graphical symbols when 3D modeling is not required, such as for plumbing fixtures, furniture, etc.
- Avoid use of extensive details.
- Create and use a default view with minimum information
- Set model view depth to a minimum
- Use wireframe or shading view instead of hidden or shading with edges view
- Turn off shadow
- Avoid using volumes
