If you are in situation that you need to work on skateboard design this template might be very useful. I've decided to share it because I've spent a lot of time searching one that is accurate, couldn't find it, so I created one.
There are four layers:
3. Clipping Mask
Idea is to keep locked "Clipping Mask" layer and after you finish with design, unlock "Clipping Mask" layer select everything and create Clipping Mask (ctrl+7 if you are using AI). Also, "Holes" layer should be left on top of everything.
