Move and rotate the UCS origin

00:04

Next, let's talk about moving the origin of the ucs.

00:08

The origin is where zero comma zero is,

00:12

you can move the ucs

00:14

by using the icon.

00:17

And when it's made selectable,

00:20

we have grips on the U CS icon. Notice when I hover over it, I can move in a line,

00:27

I can move the origin only or I can make sure that it's back in world.

00:32

And just a quick explanation here,

00:34

moving it back in world is referring to

00:37

moving it back to the world coordinate system.

00:41

I can also rotate

00:43

the U CS which we'll talk about in a little bit.

00:46

But why would we want to move

00:49

the origin where zero comma zero is?

00:52

Well, for example,

00:53

we might wanna move zero comma zero to a fence line or a property corner

00:59

so that if we wanted to start measuring angles or drawing out

01:03

the property lines from an origin of zero comma zero, we could do that.

01:09

So you'll notice I can take this grip

01:14

and I could move it

01:16

just like many Autocad objects where I could use O

01:20

snaps

01:21

and actually have it go to a specific area.

01:25

So now if I were to ID, the endpoint here

01:29

using an endpoint o

01:31

snap.

01:33

You'll see that that particular corner that I picked is now at zero, comma zero.

01:40

So because I wanna do some other things, I'm gonna undo

01:44

what I did with moving the origin, but you can see where that would have many benefits

01:51

making the origin at a different location.

01:55

Next, let's talk about rotating

01:58

the U CS. Now, why would you want to do this?

02:01

Well, one example would be to rotate the U CS to a line

02:06

so that it lines up with drawing elements that maybe

02:10

you want to draw 90 degree angles from those elements.

02:14

You could do this easily by rotating the U CS.

02:18

So what we can do

02:20

is either click on the U CS icon

02:24

and notice we can rotate the U CS with the grips

02:29

or

02:29

if we were to type in the U CS command,

02:33

notice the different options that we have

02:37

on the U CS command, one of them being object.

02:41

So if I choose object I can then come in

02:44

and let's say I want it to be lined up with

02:47

the endpoint of this line. For example,

02:52

I go ahead and pick that line

02:55

and now you can see the U CS icon

02:59

has changed

03:00

so that I'm now lined up with that particular object.

03:06

One thing I can do now is I can type in plan

03:10

and then enter and choose

03:12

the U CS

03:14

current or current U CS option by clicking, enter again

03:18

and notice how it rotated the drawing so that it

03:21

now lines up with the object that I chose.

03:25

This would be very handy when you're trying to draw 90 degree angles,

03:30

or if you want to see the drawing in another orientation.
