- [Instructor] When working in 3D sketching,
sometimes editing can get a little bit tricky.
It's hard to replicate the failures that come along,
but sometimes when you're trying to edit your 3D sketch
it's just not able to solve some of the things that you do.
Generally, you can go in, grab points, drag them around,
adjust shapes, scales, add relationships for example.
You can go in and add dimensions after the fact if you like.
So I'm just going to add in a couple dimensions here.
You know, and this is all not a big deal.
I can go in and take relations off, add them back.
For example, I could take this dimension off
or that relation rather,
and then drag this point over
and you see what kind of effect that has.
I could try and snap it over to that point.
That would be interesting.
But you see, it won't let me do that.
So that's one of the things.
The other thing is that the trim tool works
a little bit differently.
Whereas in the past you would think
that you could grab this and trim and drag,
you can basically only select entities and delete them.
So, it's not really super useful to use,
so if you need create geometry that's partial length,
you've got to basically draw it as such.
You can't just depend on the fact you're going to be able
to drag it back and forth,
and sometimes you get instances like this
where there's a relation and you can see both
of the things are shrinking and moving as I drag it,
and it's also off in space which was hard to notice
because of what orientation I was using,
so editing sketches can be kind of weird like that.
You just want to pay attention to things like orientation.
Know that you're limited in what you can do
with trimming and repairing.
Try to plan ahead and know what the structure's going to be
when you're done so you can make smart moves
and use other geometry to build those relationships.
Put points where you need them
so you can snap other features to it.
For example, I could snap from here to here.
Things like that.
And also remember that you're not going to be able
to do the trimming like you did before
and necessarily have the ability to add
as many relations as you did before.
