I need to create a hatch pattern that can accurately hatch various large geometry with very small lines. For example, I may have a rectangle that is 4" x 3". The hatch pattern that I must create contains a few intersecting lines of length 0.010". These lines form an object and, of course, depending on the size of the hatched geometry, may require many objects to create the hatch pattern.
I have successfully wrote a hatch pattern program that will complete the task to a certain degree. As the geometry I attempt to hatch gets bigger, my intersecting lines stray further away from equilibrium. If the object is to big then I will have a hatch pattern that is not constant, meaning, at the origin of the hatch pattern my lines will intersect at a center point, whereas, at the edges of my geometry the inersecting lines will be crossing at different points then the center point.
I have attributed this to the .PAT files inability to have more than a specific amount of numbers per line of code. I have approximated that I need 0.00000000000000000000000000001 significant figures. Is there a way to create this ability in a custom hatch pattern? Is there another way to program a hatch pattern, i.e. visual basic (as a plug-in), that would let me program this code with greater accuracy?
