Problem with Scale

Hi Everybody,

I am very new to grasshopper.

I have one slider controlling the Scale Y on multiple curves that are oriented to different locations.

Line 1 is 2mm long and originally located at 0,-1,0 to 0,1,0

This curve gets oriented to 0,0,-14

It does what I expect

Line 2 is 2mm long and originally located at 0,-1,0 to 0,1,0 (in the same location as Line1)

This curve gets oriented to 0,0,-16

However when it orients, it scales in Y. I am not sure why it gets longer, can anyone see what I have done wrong?

Jill

What is wrong is the orient of the first line. You have changed the length of the vectors, and that alters the size of the target line. The orient component uses a point and a vector as source, and a point and a vector as target. This means that if the source vector is (0,1,0) and the target vector is (0,2,0), the size of the geometry will be scaled by two in Yaxis.
