Discover the intricacies of grip editing for sample lines, understanding how each of the five types of grips can alter the orientation, elongation, and position of your lines. This article simplifies the process of sample line correction, enabling you to refine your lines for optimal results.
Key Insights
- There are five different types of grips that can be used to edit sample lines: two on each end of the line and one in the center.
- Each grip has a unique function for altering the sample line. The square grip reorients the end of a swath width, the triangle grip elongates the line, while the center grip slides it up and down the alignment.
- Regardless of how a sample line is created - whether it is by points, by range, or by polyline - all sample lines behave the same way when edited with these grips.

In this video, we're going to go ahead and talk about grip editing for our sample lines. So what I'm going to go ahead and do is I'm going to zoom in into this region where we created a sample line By Points, and then we also have some sample lines that were created By Range.
When we look at these sample lines, and we select one of them, so I'm going to start with the By Points, what you're going to notice is there are five different kinds of grips. We have two on this end, two on this end, and one in the center. So what we have going on here is that we have the square grip, which will actually move the endpoint of a swath width.
So it's not going to reorient or rotate the line. It's only reorienting the half of the sample line that we've created. The triangle itself is actually just an elongation grip.
And then the same thing on the other side, we're only editing the half of the sample line, the swath width of the sample line, and then an elongation of that sample line. And then the center grip will actually slide it up and down the alignment. And it's no different if you've created one By Range, or if you've created one By Points, or even if you've created one By Polyline.
All of the sample lines behave the same. It has the grip for changing the orientation of one side of the sample line, changing the orientation of the other side, elongating, or sliding along the alignment. So that's just a quick way to correct a sample line if you didn't have it drawn in the way you wanted it.

I guess I would recommend if you're going to go ahead and try and change one that isn't By Range, that you go ahead and draw how you want to have that sample line done, and then orient both of your ends by that polyline that you would create. So I'm going to go ahead and not save because we didn't change anything. I'll see you in the next video.
