I just had a look at the current feature roadmap, and grids/graph improvement is scheduled. Anyway, I think users would be more happy if we had a Guide Line tool, placing a line in a layer that is automatically set to be above all layers, current and added. The guide line tool would allow the user to draw what would look like a normal line, but with the ability to allow the user set the degree/angle of gradience at the 'Transform' tab, and also would allow snapping be enabled across the whole line, not just the vector points.
This would allow point perspective drawing and graphics, and other possibilities currently not supported. The line should also be allowed to curve, enabling the user to create abstract graphics, or even implement the golden ratio.
It would be great if this was supported, or added to the roadmap, thanks.
If you want to use anything that you have created in AD or AP with other apps you will need to export it. To do this please go to File > Export > Choose a file type suitable for you > Select the location you wish to save it. From here you should then be able to import it into your animation apps from where you saved it.
