When I used to go to college, I used to had a Graphic Design teacher who made an isometric grid using code. He had made the grid so that anyone who downloaded the template just jump straight in to the file, pick a triangle to start colouring in. However, on most of the tutorials that I have found online, it looks like you have to use the pen tool to make a shape around the triangle you want, then colour it. So, my question is, would anyone know how to make what my teacher made? Thanks.
I don't think you need a script for this, although it might help for making a grid from scratch.
Alternatively, you can easily find isometric grid templates online, like this one here
Select the grid and click Object > Clipping Mask > Release
Select all, and click Object > Live Paint > Make
At this point you could save the file again, and use it as your new template, already setup as a Live Paint isometric grid.
- Fill the cells using the Live Paint Bucket Tool.
If you want to remove the grid, Expand the Live Paint object, and ungroup. Select the grid and delete it. When you save your artwork, make sure you don't overwrite the template file - give it a new file name instead.
