Polyline with two points with stretch from one end and trim from the other

[Umar]

Hi.

I am looking for two lisps actually.

1. Draw two polylines by selecting two points 'A' and 'B'. These polylines have same length but mirrored from the center of two points and spaced a certain distance apart, say 400mm. The polylines are stretched 75mm from point A and trimmed 0.15*dist. between two points.

2. Draw three polylines by selecting three points 'A', 'B' and 'C' having a certain distance and certain length from the 2nd point. All three polylines must be centered between Point 'B' and point 'C'. For example, the length of longest polyline is (0.3*L + dist. between point 'B' and point 'C' + 0.3*L) The situation is illustrated in the figure.

I thank you in advance to all of you who would take some time to help me in this. Hats off to you!
