- One of the most powerful features
that we can use inside of the sketch
is the Trim and Extend feature.
Let's run through that real quickly.
Up here in the command ribbon
we find the Trim Entities button.
If we click on the drop down below,
we see Trim Entities and Extend Entities.
Now Extend Entities is pretty simple.
We just click on it,
you select an entity,
and it'll extend to automatically the next logical line.
So I can click on this and extend there.
I can click on the line again
and keep extending it out farther and farther.
As you can see, this line cannot extend any further,
because it doesn't run into another feature,
but this line will extend,
and this line would extend.
So just simply hovering over the line and then clicking.
Then you can keep clicking and watch it extend through.
So that's a pretty powerful feature.
What I really like is the Trim Entities feature.
You go ahead and click on Trim Entities.
I usually keep it on Power trim.
You can use some of these other options,
the Trim Corner, Trim away inside,
Trim away outside, or Trim to closest,
but honestly, the most powerful way to use this
is by using Power trim.
You simply start in one area on the screen,
hold down your left mouse button and start dragging.
Now you can just barely see it,
but there's a gray line where I'm scrolling on the screen.
So as I bring this over
and start hovering through other entities,
it'll just start trimming those lines back as I go through.
And you can see it makes that red dot
behind me as I trim each line,
and you can see it just literally trims
where I drag to the closest extents.
Now while I'm holding this button down,
I still haven't let go,
I can also drag back, and if I hover over that red button,
I can reverse the trims that I've made as well.
So if I've trimmed too far, I can simply back up
and untrim those features.
So this is pretty powerful stuff, pretty awesome,
but if I wanted to, I can just drag it through quickly,
and trim all kinds of shapes, let go, and it'll trim.
You can use the Corner trim,
if you want to trim a corner in between two features.
You could use Trim away inside,
but it's kindof tricky to use,
and you've got to get it inside of a feature.
You can use Trim away outside,
same kindof thing.
I got to escape real quick, because it just got hung up.
But those features don't really work that awesome.
I'm honestly not even sure what the point of them is.
Typically when I go in,
I just use Trim Entities, keep it on Power trim,
and then I can trim everything
with just the drag of a mouse.
And if I want to, I can drag back through those
red bread crumbs and undo the dragged features as I go.
If you want to undo all those changes when you're done,
you can just hit control Z or undo,
and it will go ahead and undo all of the trim,
so you don't have to get too hung up
if you don't like what you see.
The trim is not permanent.
