"Construction drawings are used to build your project in the real world. Professional markings communicate where and how things should be built. Drawings may show elevation, depth or multiple views of a design. Construction drawings are invaluable throughout the building process, whether they are used to understand a building’s position on its land or show crews where to dig the first hole and how deep it should be.
Construction Drawing - Level 2 shows that your drawings are clear, and you show that you are thinking in 3D even though you are drawing in two dimensions. Even if you are not using more advanced techniques yet, you are getting there."
- "Your line drawing is clear and begins to use dimensioning and symbols Your drawing is somewhat accurate and detailed, even if it does not show depth"
