imprecise scatter brush with illustrator


New Member
Hi! I'm a cartographer, when I use scatter brush in Illustrator the brushstroke move away from the original path making an approximate shape ,I wish this did not happen.
I have already tried with a brush pattern too, in this case the path is precise and constant without tolerance but the shape of the pattern is deformed but I need the pattern to remain unaltered. The issue lies within the object's size , it happens with tiny object I don't know if this is a bug . When I make a large brush and then scale it down using the stroke width, you will run into the issue as well.
I also attach the illustrator file that contains the brush with the problem: illustrator file
