Create additional grids and levels

00:03

After completing this lesson, you will be able to create grids, create levels, modify grid and level family types,

00:11

create structural plans, and also work with scope boxes.

00:16

The objective domains covered are, 5.3a, modify level and grid types and, 4.1b, view properties.

00:25

A structural grid defines locations for elements such as columns and walls.

00:30

If the grid line is changed, the elements that are referenced to them would also adapt.

00:36

Levels define building stories and create and control vertical datums.

00:42

Many elements can be created to start and end on building levels.

00:46

If the level changes, then referenced elements would also adapt.

00:51

A scope box can control the visibility and extents of datum elements such as grids, levels, and reference planes.

00:58

In the example below, two scope boxes are used to control the position and vertical extents of a grid.

01:06

Go ahead and open up the file 003-Create additional grids and levels.

01:12

Note in the project browser that the active plan is level 1.

01:16

Our first task is to create structural grids from the architect's linked file.

01:22

To do this, we'll select the Structure ribbon, and then go ahead and pick the Grid button.

01:29

On the Context ribbon, we're going to utilize the Pick Lines method.

01:36

I'm going to begin by selecting the grids in sequential order.

01:40

So this is grid1, so when I select this, you'll see that Revit then creates a new grid referenced from the architectural grid.

01:46

I can then proceed through the rest of the sequential grids, and then Revit creates a new grid based on the architect's grid lines.

01:58

Here, you'll notice that Revit references this as grid 10.

02:02

Whilst we're in the Grid command, we can simply put a new reference in. In this case, 9a.

02:09

So we now need to create the multi-segment grids used on grid A, B, and C.

02:15

To do this, we'll select Multi-Segment.

02:20

Again here, we can utilize the Pick Lines.

02:24

And we can then pick the two lines representing grid A.

02:29

Once I've selected those, I can select the Finish Edit Mode.

02:33

And again, it's important then to rename the grid.

02:41

I'll then right-mouse and repeat the Grid command, select Multi-Segment, and then select Pick Lines, finish the edit mode.

02:55

And note that this has now taken on the next grid, grid B.

02:60

Let's repeat that whole process for grid C.

03:11

We can then create the last three grids by clicking Grid, and again, by going directly to Pick Lines, and picking off the last three elements.

03:28

Our grids are now created.

03:30

To enable us to see these better, we can go to Visibility/Graphics and switch off the linked model.

03:37

On the View ribbon, select Visibility/Graphics, on the Revit Links tab, uncheck the architect's model.

03:48

Here are our structural grids.

03:51

Once these grids are created, it's recommended that the grids are pinned, in case you accidentally reposition these.

03:57

So we can window select all of the grids and select Pin.

04:07

Note that the arrangement of grids looks quite untidy.

04:10

The reason for this is some grid heads are displaying on end one and others are displaying on end two.

04:17

We're going to edit the family type of the grid and consolidate this.

04:23

So select one of the grids.

04:26

And you can note here that all the grids are using this family type quarter inch bubble.

04:31

Let's go ahead and click Edit Type.

04:35

In the Type Properties dialog box, you'll notice here that we have our symbol used for our grid.

04:41

But also here, you can see that we have two options.

04:44

The plan view symbols end 1 and the plan view symbols end 2.

04:49

I'm going to ensure that both of these options are checked, and then click "OK".

04:56

So now note that the arrangement of the grids looks much nicer.

05:00

We also need to suppress the two grid bubbles on grid F, so I'll go ahead and select both of these.

05:07

And here's the arrangement that we were looking for.

05:11

We can do a very similar thing with the levels.

05:14

So in our project browser, let's switch to the South elevation.

05:22

On the right hand side here, you can see that we have our levels currently being shown.

05:27

All of the symbols are on the left hand side.

05:30

What I'd like to do is edit these so the symbols only appear on the right hand side.

05:35

So we can select one of our levels.

05:38

Again, in the Properties palette, we can click Edit Type.

05:43

And again, note here that we have symbol at end 1 or symbol at end 2.

05:48

We'll ensure that symbol at end 1 is checked and symbol at end 2 is unchecked.

05:55

And here are our levels updated.

05:58

Next, you generate structural plans from the levels we've just created.

06:03

On the View ribbon under the Plan Views dropdown, select Structural Plan.

06:11

Select all the levels in the list, and click "OK".

06:18

Revit has now generated all of the plans.

06:22

We now create a scope box to control the grids on the right hand side of the structure.

06:28

On the View ribbon, select Scope Box.

06:36

We're going to create a scope box just roughly about this size here.

06:40

This is an arbitrary dimension.

06:43

What's important now though is I rotate the scope box to match the rotation of my building structure.

06:50

You'll notice here that we have a Rotate tool built into the scope box, but this won't allow us to accurately define the rotation.

06:57

So instead, we're going to use the Rotate command.

07:03

We'll place the center of rotation on our grid.

07:08

And here, I can pick a straight horizontal line, and then snap the scope box to the same rotation as our grid.

07:18

We can then use the shape handles on the scope box to fine-tune the overall size.

07:26

In the Properties palette, you'll notice that we can give the scope box a name.

07:31

So I'm going to call this one Wing B.

07:36

And I can then select the grids that I'd like to control with this scope box.

07:44

Once I have the grids selected, notice here, I can select the particular scope box that we'd like to use, in this case, Wing B.

07:56

So you'll now notice that grids have updated to that scope box.

08:01

You may want to change the vertical extents of our scope box.

08:05

We can select the scope box, and in the Properties palette, under View visible, we can select Edit.

08:13

Note here, that in the 3D view, I could override the visibility and set this as visible.

08:20

And I'll do the same in the South elevation.

08:27

If we now take a look at the South elevation, you'll now note that my scope box is visible.

08:32

And once again, I can use the shape handles to control the extents of my scope box.

08:43

If I wanted to, here, again I could select my levels.

08:52

And I could assign those to the same scope box.

09:01

Note in 3D, we also see the scope box.
