First and for all, sorry for the rough sketch and grammar. I would like to ask is that even possible for an object to have different vanishing point length? I find this problem when i start drawing object with different vanishing point length. Question is do i need to maintain the same vanishing point length or not? There are two example there. Example 1: I find the first object vanishing point and the length of it. I copy the first length and drag it to different vanishing point for my second object. Example 2: I find the first object vanishing point and the length of it. However, I draw different vanishing point and different length for it. May i know which one is correct? Or none of it is correct. If so please guide me or teach me. I really want to learn and know it. Many thanks in advance :)
