Grip edit a profile

00:05

in this video.

00:06

We're going to address the last editing method that we

00:08

have available to us in our profile creation methods.

00:11

That editing method is editing using grip edits.

00:15

So what we're gonna do is we're gonna select our design profile.

00:18

And when you see this,

00:19

what you'll notice is that there are multiple different grip types.

00:23

We have triangular circular and square grip types.

00:26

Square grip types are associated with our tangent sections.

00:29

And what they do is they maintain the gradient that we have going between the two

00:33

curves and it modifies the two tangents coming

00:37

out but retains the vertical curve lengths.

00:41

So we're actually modifying the two exterior

00:44

tangents by moving this interior tangent.

00:47

Moving on from there we have these circular group edits and

00:50

these specifically deal with the length of our vertical curve.

00:54

So as I move this in and out,

00:56

I am shrinking and expanding the vertical curve length and when I

00:60

get to a certain point you'll notice I can't move past a certain

01:03

point and that's because on the opposite side I'm running into a

01:07

conflict with the nearby vertical curve on the downstream side down here.

01:11

Moving on from there we have this blue

01:16

circle edit

01:17

right here,

01:17

grip edit and by moving this inwards and outwards you

01:22

can change your vertical curve using this method here.

01:25

Then from there.

01:26

What you can go ahead and do is you can

01:28

grab this grip here and this will modify the two tangents

01:33

on either side of your vertical curb but it will

01:37

maintain your curve length so you can move your P.

01:41

B. I. Around Is basically what this grip edit is doing

01:44

then from there, you have these

01:46

which they lock in the tangent C. And this grade of one component of the P. D. I.

01:52

So if you want to maintain this tangent C. Here, you would grab this grip here

01:57

and if you wanted to maintain this tangent, see here,

01:59

you would grab this grip here.

02:03

There's not much play here because of this close vertical curve,

02:06

but so if I went to this one here and I selected this group here,

02:10

I could pull it this way.
