CAD Layer, Viewport, and Plot-Control Laboratory
Manage a multi-discipline layer set, apply viewport-specific visibility, test two-dimensional sheet fit, inspect lineweight output, and verify the final PDF and print.

ByLayer discipline
Colour, linetype, and lineweight should normally inherit from the layer so a drawing standard can be reviewed and updated consistently. Use overrides only when documented.
On, freeze, lock, plot
These controls solve different problems. Visibility does not imply plotting; locking does not hide geometry; viewport freeze is sheet-specific; non-plot layers require deliberate review.
