I created this isometric grid, via the SSR method described in this tutorial.
However, when drawing a rectangle, and copy-dragging it the 'rectangles' do not align. When drawing a straight line i see that the grid is not perfect vertically although i followed every step;
1: create grid (1000/1000 pixels, 30 collunms 30 rows) 2: scale the grid vertically (86.602 %) 3: shear 30 degrees 4: rotate -45 degrees 5: make guides
I tried it again and again and i never get a perfect grid. Working on windows 7 // Illustrator CC 2014
