When working on complex designs that will be realized in wood, materials can be a real drag on productivity. Projects can easily contain dozens of parts. Applying materials to all of them can be very tedious. If you want to be able to edit the materials efficiently, you are forced to draw all parts in the orientation of the material. While this is efficient in terms of the ability to update materials, it can make drawing more difficult than it otherwise would be. In addition, it is very painful to get the appearance of rift-sawn wood with this method.
