Hi...

A [curve 2] will give you a perfect line.
With [cos ] and [sin ] you could "easyly" convert the angle in x, y for the second point...

But, I'm not sure that using a rectangle, in your case, is neither so difficult...
Before the rotation, you just have to translate the rectangle of the half of the lenght it grows.
It's not a "trick" and works very precisely.

Cheers.

Hi all,
I've been trying to render a line in Gem, so I'm wondering if it's
best to use [curve] (which is actually a curve as it indicates), or
[rectangle] with a very small x value, so that it looks like a line.
 My problem is that I want to give this line an angle, so I've been
using [shearXY] for now. I also want to make the line grow from
nothing to the full desired length, but with [rectangle] it will grow
from the middle, so in order to make it grow from the starting point
to the ending point, you have to give [rectangle] a continuous x,y
offset.
 This way it's really hard to determine the starting and ending point
of the line. So, If for example the x,y coordinates of the starting
and ending point are random, then the angle and length will also be
random and you'll have to manipulate three different objects
simultaneously ([rectangle], [translate] and [shearXY]), and I'm not
sure if I can find the formula for all these calculations.
 Is there an easier technique for this?
