Drawing custom perspective grids
Most projects don't start in Illustrator or need at least some kind of reference to draw around - for example a product picture or rough sketch. So in most cases Adobe's perspective tool in Ai is absolutely useless. There is simply no way to always find the right perspective in your reference with that tool!
Many professionals draw custom grids with the help of an odd star with very long and thin end points. They draw one, two or three stars depending on how many vanishing points they have. This is a super old and powerful technique of illustrators and anime artists - but there is no such thing in the same called program to help... We need a more usefull perspective tool with the feature to shift your objects on to one side, floor or ceiling like Adobe's tool does. That's genuinely a good feature but the setup of this grid is just a drag! Make it as easy as drawing to lines on your object that are likely to touch each other when extended and BAM right there will be a star with as many endpoints as you like or just even a slice, not a full circle.
