Setting up shared coordinates

00:04

In this file, we have our topography modeled

00:06

along with the road and other site components.

00:09

Plus, we have two linked models,

00:11

one for the residence block

00:13

and one for the studio block

00:16

looking in the site plan view,

00:20

we can see we have the coordinate markers for our current project,

00:24

have the internal origin point, the project base point

00:27

and the survey point.

00:29

And they're all currently in the same location.

00:32

This means that the coordinates for this model

00:35

are being generated from this location.

00:39

So to show this from the annotate ribbon tab on the dimension panel,

00:43

I'll choose to place some spot coordinates.

00:46

If I select the end of the slab down here,

00:49

we can see that that coordinate has a minus north value.

00:52

That's because it's below the actual origin point.

00:56

And I'll specify a point up here by this path.

00:59

We can see that that has a positive value

01:02

and the eastern value are the same on both as they're on a vertical line

01:06

and they're just 8 ft or so to the east of this coordinate point,

01:10

we can see the linked models and their coordinate points as well.

01:14

And we can see that they're all in the same location within their models.

01:17

And these models have been positioned by just moving,

01:20

rotating and aligning them into the correct location

01:23

within this site file

01:25

as we now have them in the correct location,

01:28

we'll set up some shared coordinates.

01:31

And this means that should we need to link the two blocks together in their own files,

01:36

we can use the shared coordinates to position them accurately

01:39

and equally, we could link the site model into either of these blocks

01:43

using the shared coordinates.

01:44

So that would come in in the right place relative to the buildings.

01:49

We can also set up shared coordinates between rev models and DWG files.

01:55

And this can be particularly useful if the DWG

01:58

has been based on a survey or official GIS data

02:02

as it will contain the correct coordinates and north orientation for our site,

02:07

we have ad WG of that nature for this project.

02:11

So we'll go to the insert ribbon tab

02:13

from the link panel. We'll choose to link CAD

02:17

and we'll choose the home studio GIS plan.

02:20

We'll leave the import options as they are.

02:22

We'll note the position and is currently auto origin to internal origin.

02:27

So I'll open this up

02:30

and now zoom in out, we can see where our DWG has been located.

02:35

So not only is it away from the current site, it's also at a different angle

02:39

and this is the true north orientation of our site

02:43

as opposed to the convenient angle that we have it on

02:46

because it's easier to work on the screen when it's straight rather than rotated.

02:52

So to set up the shed coordinates, we'll first move the DWG to align with our

02:56

site.

02:57

So we'll select this

02:59

and because we bought it in origin to internal origin,

03:01

we'll need to unpin it before we can move it.

03:05

So we'll now choose move,

03:07

we'll select a convenient location such as the end of the slab here

03:10

and we'll snap that to the end of the slab in our

03:13

model.

03:16

And whilst it's still selected, we'll now rotate it.

03:18

So from the modify ribbon tab, we'll choose, rotate,

03:21

I'll choose to place the center of rotation

03:24

and we'll place it

03:25

at the end of the wall where we've just located it.

03:28

And now we can select the line in the DWG file and align that to our rev model.

03:34

Now zooming out,

03:35

we can see that the CAD drawing perfectly aligns with our rivet site.
