Important tips in Flat drawings for production:

Footwear flats can be drawn with top and side views or a three-quarter view, depending on the need to show specific details.

Therefore, need to be accurate in dimension and proportion.
Every aspect of a shoe’s design must be shown clearly so the developer or pattern-maker can understand the shoe’s individual features.

Flat drawings for production samples

Once the pencil shoe design is complete, a permanent black pen line is added to make the lines clean and easy to read in three distinct line weights:
bold is used for the outside silhouette (which keeps the shape strong), medium for construction detailing (which is the main purpose of the drawings), and a fine line for adding texture, reflection, or shadowing.
Use straight edges and French curves to ensure smooth line work.
Once the ink line is dry, the pencil line is erased, leaving a sharp, graphic image.
Typically color or soft rendering is not used on flat drawings.
Think of them as an architectural drawing for an object.
