So in this lesson, I want to talk about two concepts. One is straight lines, and the other one is Bezier curves. Let's see. So the first thing we're gonna do is come here to the side toolbar, and we're gonna see this little tool here, you can also press P in your keyboard to activate it. So basically a vector line or a segment, it's created by a minimum of two points, one for starting one for ending. In Affinity Designer, you're going to find the ending point is always a Red Square circle with red stroke, and if selected, also Bluefield and this is basically very simple path or segment.

Now, we also have a possibility of transforming these straight line with sharp angles into curves or Bezier curves. So I just click and drag, and I'm going to have a soft curve as you can see in here. Another thing to talk about here is that this is what we know, as a soft point, we're going to call them point for the time being. And this is a sharp point, the difference between these square points and this rounded point is clear. What you're going to get out of these ones is going to be straight lines and sharp angles. Whereas with the soft points, you're going to get Bezier curves that are soft.

So if you take a look here, you're going to see what is known as handles or control points. And they are what you use to manipulate your curves. So if I come here and I trace another portion of my vehicle and I draw you can see how It's changing the shape of my curve. You can also see that they move along together, they grow together, and they have the same distance to the point that originates them. Whenever this is happening, you're gonna see these little perpendicular lines right in the center of each one of the handles, meaning that this handle and this handle are exactly the same length. What now, if I want them to move separately?

Well, what I have to do is come to my keyboard and I'm going to press and hold Alt or Option and command. Now you can see my pencil is transforming into this other icon like an arrow. So I come over the handle and now you're gonna see this soft point is going to transform into one of the Sharp ones, meaning that's my next segment is going to create a sharp angle here. So I click now here, and even though this is a curve, if you take a look, you're going to have here, a sharp angle. If for whatever reason, I would like to make the next one, a straight line, what I have to do is click on this point, get rid of one of the handles, and I'm free to keep going. Now if you need one sharp point to have handles you have two possibilities.

One will be going over even polling converting your path into a curve which will create a soft points with the handles we saw before And the other one would be pressing and holding Alt, or option and polling. Now you're gonna have a SharePoint with a handle, but the next portion of this segment is always going to be a curve no matter what you do. So to wrap up I repeat, this is what is known as a path. It can be formed by straight lines, and it can be formed also by Bezier curves. Now, this is a starting point, and this is an end point. Smooth points.

Always have hundreds. Sometimes you're gonna have a handle in a sharp point, if it's united to oversee occur, however, you can see here, these ones do not have handles The perpendicular line in the middle of the handles means each one of them are the same distance to the point that creates them. And whenever we want to move a handle, we press and hold command and move both of them. And if we want to just move through one of them, we press and hold, command an alt, and now we can just affect one portion of our curve. And now as a short appendix, I would like to talk shortly about how to select sub select group and ungroup things in Affinity Designer for those of you who are complete newbies, and so you follow along much better. In this course, I'm going to show you how to move group and ungroup things in Affinity Designer, how to move them in your canvas and how to use your Layers panel.

Which is this near to the right if you don't have it, come to you Studio and layers, click on there and you will get it. So the first thing is we have this rectangle, this object here, and we have a second object here. If I want to move them, I have to select the Move tool or press V in my keyboard this way, if I drag and select both of them and press Command G in my keyboard, I'm going to group them. If I want to move them, I can do so with the move tool. And now I obviously move them together because I group them if I want to sub selects this orange in the group, I have three possibilities. I can here expand the group and select it like so.

Now I can move it or I can also double click and sub selected. I can also select the note tool by clicking a marquee are also holding command or control with just one click, I selected. Okay, so this is basically the way you're going to select sub select group and ungroup in Affinity Designer, and well I hope now you can follow along much easier. See you in the next lesson. Bye
