The wheels of the little mine car are a great exercise to practice our building of various shaped reliefs and how to merge them into a final shape which we want. As we build the reliefs we have to keep in mind the final result and then think of what we have to add or take away to get exactly that. There are many ways we could have achieved a similar effect.
The back flanges on railway wheels are sloped so the first task was to create a disk using the largest vector circle. I kept it fairly shallow.
Then I selected the next vector and created a flat disk 0.9″ tall. This was then merged with the first tapered disk I created.
Then it was time to knock out the center to make room for the spokes and the hub of the wheel. I created a zero height relief which was then merged to the base relief.
Next up was the spokes. I first created flat reliefs in the shape of the spokes.
The spokes looked good but I wanted them to be curved on top and higher in the center. THis would need to be done in a couple of moved by modifying these reliefs. First ‘I used the done tool to puch down the center in a bowl shape.
Then I used the prism tool to modify the reliefs once more by building them over a cone shape.
These spokes were them merged highest with the base relief.
The last step was to add the center section of the hub by adding to the relief.
