So we're going to look at this trim and extend command now AutoCAD.
Sometimes it makes improvements to commands and.
Yeah, they're not always improvements straight away.
Sometimes they need a bit of work.
In the latest version, they did change the trim command a bit.
Personally, I liked it the way it was.
The new command works.
It's a bit it works how you how you would want it to on a basic join.
But when you get into advanced joins it can be quite resource hungry I've found and because I don't
know what computers you're working on things like that it's easier if we just set it to how it was,
which is how you'll find it if you ever work on an old machine.
Okay, so what I want you to do is type in trim mode.
Okay, so tr I am mode and yours might be set to zero, whatever it's set to.
We want to set it to one.
So just type in one enter.
Okay.
And there you go.
And now all our trim modes will be the same.
So this lesson will make much more sense and we'll look at trim and extend it is basically how it sounds.
So let's say we've got a line, we've drawn a polyline and we've got another line and someone's drawn
that either didn't have the snap turned on or it was just rough, or maybe you're just editing it down.
Okay.
You want these lines to be a right angle?
You want them to you want to trim these loose ends off.
So we'll go to trim.
And it's going to ask us trim objects.
Okay, So we want to select that object and then we right click.
And now it'll say select the object to trim.
So we want to trim that and right click.
Okay.
And that in essence, is the basics of that command.
So.
So you select the first object is the object you want to use as kind of a trim edge where you want to
trim to.
You right click and then you select the object you want to trim, but you're selecting the side.
You want to disappear.
Okay, so whichever side you select is the side that will disappear like that.
And it's not just used on corners.
Let's say we had something like this and we had a line coming through.
We'll select trim and we want to trim objects.
So we're going to select multiple objects by doing a window up that way.
Remember, if we do it that way, we only need to touch them.
If we did it that way, we'd have to go the whole line.
So we'll go up that way and it's going to select these four lines and we right click and now we can
trim in between those lines and right click like that.
There you go.
Okay, so that's the trim command.
Next to the trim command, we have the extend command, which you've probably guessed what it does.
It's similar.
It just does the opposite.
So.
We want to extend an object, where do we want to extend it to?
So if I select this line and right click, I can then select.
Well, it will extend it.
Okay.
And again.
You can select multiple.
So we could extend that one in both directions.
And that's just left clicking.
I'll go through that click again.
So extend.
So we left, click the command, we left, click the lines we want to extend to right click to say we've
finished the selection and then we left click the ends.
It's important.
It's going to want you to click towards the end of a line.
You want to move.
Okay?
And it will.
It's quite intuitive.
It will know it automatically.
And then to finish that command, we right click.
So that's the trim and extend command again.
You'll use those a lot.
