Answer :
Final answer:
Projection lines in orthographic views are perpendicular to inclined surfaces, not at a 45-degree angle.
Explanation:
Orthographic Views and Projection lines
Projection lines in an orthographic view should be perpendicular to the inclined surface, not at a 45-degree angle.
For example, when representing an inclined plane in a top/front/side view, the projection lines should be drawn as parallel lines to the inclined surface, intersecting the top and front views at right angles.
Therefore, the statement 'Projection lines should be at a 45 degree angle to the inclined surface on an orthographic view' is False.
