- [Instructor] By default when working in SolidWorks,
if you add a dimension to any entity
and then go to drag or move that entity
after the fact, it maintains that dimension.
So you can see as I drag this line around, it's still trying
to maintain that three-inch point 29 dimension.
Same with this line and its angle.
If I go to rotate this or slide it,
it's going to maintain that angle and that dimension.
Same with this arc, if I drag it out,
it's not going to do anything, it's actually not even moving.
I can grab its center point and move it,
but I can't drag the exterior and change its dimension.
Same with these two lines that are dimension to each other.
I can grab them and drag them together,
but their dimension stays the same.
Now, if I go to Tools, Sketch Settings,
and Override Dims on Drag/Move,
what this gives me the ability to do is maintain
those dimensions, but adjust them as I drag these features.
So I'm going to turn that on, go up here,
and just start dragging this line.
You can see now the line moves
freely away from the other line,
and when it's done the dimension updates.
I can do that with this hole, make that bigger on the fly
without deleting the dimension and re-adding it.
I can also rotate this angle out, change that,
or change the length and the position of this line.
So you can see that's not always going to be the case.
Typically when you add a dimension, you're doing it
to constrain something in your sketch feature.
But if you're doing something where you need
some adjustability, you've got it sketched pretty close
and it's got good relations in it and you just need
to adjust some dimensions, but you don't know
what the dimension is, you kind of want to do it by eye,
you can turn this on and just kind of click and drag your line
or your circle to where it needs to be.
And then you're good to go, your dimension's going to update
and you can keep moving without having had fudged
and moved between various points,
tried various different dimensions
or incrementally grew or shrunk your dimension.
Again, to repeat, you can find this feature
in Sketch Settings, and it's Override Dims on Drag/Move.
When you're done with it, you just go in here
and click on it again, the check mark will come off,
and it's back to normal where we're not going to be able
to adjust any of these sizes or dimensions.
