The first sample was the letter a on a 'riveted plate' panel. This panel used a variety of techniques to build and is a fun one to paint for the students. If you are following along and look close you will see I made a mistake on how the bottom two plates overlap. I had to back up a little and move the bottom rivet to the left and make the bottom left plate be on top of the one on the bottom right.
The entire file was created in EnRoute. The plate vectors were originally perfectly square but with the handy new distort tool (EnRoute 5) this was taken care of in a jiffy.
Then I added an outline around the letter 'a'.
Each plate was treated as a separate relief - all the same height.
To bend the plates up a little and allow them to overlap I had previously created a bitmap called 'uneven blend' It's on the TEXTURE MAGIC COLLECTION
This was applied to each individual plate in sequence.
The plates were then nudged up or down as necessary in the front view using the up/down keys.
Next up were the rivets... a simple process using the done tool.
The lettering outline was then created as a simple flat relief. I then went to the front view and nudged it upwards into position.
The letter 'a' was then added to the relief by modifying the new combined relief. It was at this point I realized that I had made a mistake in the relative elevation of the angled plates.
This is where the undo comes in handy. I backed things up to where the plates were separate and adjusted the heights in the front view.
The file was now ready to tool path and send off to the MultiCam. It would be machined from 1" thick 30 lb Precision Board.
