Accuracy of drawings throughout design process
Understanding of thickness of materials
Awareness of the modelling process.
When designing these models, I had to constantly keep in mind the modelling process and how each piece would fit together. This is important when doing drawings with accurate measurements as each size of each piece begins to relate to the other e.g a shelf which is 3mm thick must fit into a space on the wall with the same thickness. Whilst this made the design and drawing process very technical and time consuming, it will now mean that manufacturing of the models will be significantly easier- with less need for additional quality control (since the pieces are drawn accurately by a laser cutter, reducing the risk of a human error).
The reason that I have found google sketchup the most productive way of modelling is because it reduces the time spent on considering perspective in design drawing- meaning that I can accurately draw my designs in a more direct and focused way.
