In our conception, this is the first stage of product development, which can be described as a sequence of steps from shape and function formulation to digital 3D sketch. It respects both the so-called package that summarizes all the basic dimensional, safety, functional, ergonomic or production-strategic requirements, as well as the high quality requirements for the creation of main surfaces. The resulting 3D sketch becomes the starting point for the next stage in development – detailed modeling of shapes or technical sections and computational analysis.
See below – the process is described on a standard car.
Hand sketching is irreplaceable when analyzing assignments, brainstorming ideas, discussing projects with colleagues or customers and choosing the best idea for further processing.
So-called package, which combines basic dimensional, safety, ergonomic and production strategic requirements (Carry Over Parts - COP such as windows, door handles etc.).
Shading focused on emphasizing shape when searching for the right proportions and the best fitting model, to both the 2D sketch and the technical description (package).
Shape cleanliness check, so-called “highlight check” or “zebra”. The shape and curvature of the lines detects problems.
