Drafting - Drawing 3D shapes in different perspectives and using Google Sketchup to draw shapes according to proper measurement.
Two Point Perspective:
- Draw your horizon line.
2. Place your vanishing points on both ends of the horizon line.
3. Receding lines are next drawn from each end of the corner to each one of the vanishing points. These lines are called orthogonal lines. Any set of parallel lines that recede away from the viewer will follow along these lines to one of the vanishing points.
4 . Draw a line in between the two vanishing points and cross over the horizon line. This line will become the corner of the building.
5. Erase the lines and there you go!
