Using mirrored/drawn objects as guidelines for drawing lines

[tany0070]

hi, i want to know how to write a code that allows me to draw a line for a known point to a point along a "guideline" created by mirroring/arraying some originally existing drawing. position of the end point is determined by how many lines are required to be drawn. please help, thanks. [see attached file for illustration] oh and the outline is suppost to be hidden from user.

Can you post a diagram showing what comes first, next, etc?

I am looking at the picture you supplied and trying to understand
the process flow of your routine.

ok, it actually has multiple steps, i'll show them from no lines drawn to everthing drawn [order in b4 -> n1 -> n2 -> n3]. thanks.

hi pple, i believe this thread went dead because not many understand what i want. i'm posting so new images hopefully someone will understand and help. the module will locate the drawing start point (one of the edges of the white rectangle) and draws a line down to the yellow out-of-shape box (see image 3 for this). oh and it is suppose to do this at every inner edge of the rectangles (i.e. the two edges nearest to the yellow out-of-shape box). thanks

I think people here do understand . . . that here is more mathematics for you to do, than lisp for us. . .
