Working with selection sets

00:04

After completing this lesson, you will be able to understand selection methods, create selection sets, edit selection sets, and load selection sets.

00:15

The objective domains covered are, 1.3a, use selection sets.

00:21

Most of the editing commands in Revit require a selection set to be defined.

00:26

In order to complete this task efficiently, you should understand a few fundamental tools for selecting elements.

00:33

Select all instances is a fast and efficient method of collecting multiple elements of similar properties.

00:39

Filter is used when multiple families are selected and you wish to remove certain items from the selection.

00:46

Once a selection set is being made, you can save these sets for future use.

00:50

This tool is found on the Manage ribbon.

00:53

To recall previous selections, use the Load Selection tool, also found on the Manage ribbon.

01:00

Go ahead and open up the model 019-Work with selection sets.

01:05

The model opens up in a 3D view.

01:09

We'll begin by looking at select all elements in a view.

01:13

If I select one of these concrete columns here and then right mouse click,

01:18

you'll note that I have a very fast way of selecting all elements similar to this one.

01:22

I have two options, Visible in View or In Entire Project.

01:27

In this case, I'm going to use In Entire Project.

01:32

Upon the context ribbon, you'll note here that we have the Filter tool. Let's select "Filter".

01:39

In the Filter dialog, I can confirm that I just have Structural Columns selected and I have a count of 26 items.

01:47

Go ahead and select "OK".

01:50

This time I'm going to use a window selection to select the entire model.

01:58

I can then go up to the context ribbon and select the Filter option once again.

02:03

This time you'll note that we have multiple categories selected.

02:08

If I just want the structural columns to be selected here, I could select "Check None" and then select "Structural Columns" and click "OK".

02:18

We now just have structural columns in the selection set.

02:23

These selection methods are relatively simple to achieve.

02:27

However, if we zoom up on the steel work on the roof here,

02:31

you'll notice in this section here, we have these parapet support beams that I might want to select.

02:37

Now, all of these parapet support beams are fairly short in length.

02:41

Now, of course, I could hold the "Ctrl" key down and then go around and start to manually select all of these.

02:47

But there is a quick way to do that.

02:50

If we look in the Project Browser, you will note I've set up a Structural Framing Schedule,

02:55

that just reports on the framing organized by its cut length.

03:01

Now I can see here that all of these framing members using the HSS3x2x1/8.

03:07

I can select all of these here and then select the 3D view again.

03:13

Just to ensure that I have only selected those parapet support beams, I can go ahead and utilize "Isolate Element".

03:21

And now, I can just confirm that I have those parapet support beams selected.

03:27

Let's go ahead and reset my Temporary Hide/Isolate.

03:32

Now, what I can do here is I can cite this selection set so I can record it at a later date.

03:40

Let's select the Manage ribbon and on the Manage ribbon, you'll note here that I can, in fact, save a selection.

03:48

We'll name the selection set "Parapet Support Beams" and click "OK".

03:58

The selection set has now been saved.

04:01

If I want to record a selection set, I can pick something else just to remove the selection, and then on the Manage ribbon, I can load selection set.

04:11

And in here, you'll note that I have my parapet support beams that I can select and click "OK".

04:19

Finally, I can edit a selection by going to the Manage ribbon and selecting "Edit Selection".

04:26

Here, you can see that I have some rule-based filters setup, but here our selection filters are displayed.

04:32

So you can see here that I have my parapet support beams, here I could edit the selection set.

04:39

In this example here, I could select some of these and remove or add them using the context ribbon up here.

04:46

Or, in fact, I could simply just delete the selection if I wanted to.
