Working with revisions

00:04

After completing this lesson, you will be able to understand revisions, create a new revision, and work with revision clouds.

00:12

The objective domains covered are: 3.4a, understand sheet issues/revisions.

00:26

When changes are made to a drawing and the drawing has been released, you should create a revision and log this in a revision table.

00:33

The changes to the drawing sheet can be indicated with a revision cloud and a revision tag.

00:38

You can either control the revisions globally in a project or per sheet.

00:43

This has to be decided before any revisions are created.

00:48

Go ahead and open up the model 031-Working with revisions.

00:53

The model opens up in the Sheets view, S005-02 Steel Framing.

01:00

Most sheets and drawings will contain revisions.

01:03

And you can see here, we have a revision table that's embedded in a drawing sheet.

01:08

Also, the drawing sheet here will report on the current revision.

01:14

Revit's revisioning system allows us to create revisions per project or per sheet.

01:21

Let's take a look at these revision settings.

01:23

On the View ribbon, select "Revisions".

01:28

In the Sheet Issues/Revisions dialog box, you can see one row has been added, and this is the first issue.

01:35

You'll notice that the numbering is alphanumeric.

01:38

We have some options here, we can have numeric, alphanumeric, or none.

01:43

Then we have the date, description, whether it was issued or not, the issued to, and issued by.

01:50

In this case, I'm going to issue this.

01:52

Now when we do this, you can see then that we can't make any edits or changes to that revision because, of course, the drawings have been issued out.

02:00

Let's also take a look at the numbering.

02:03

So you can see here, as we've just discussed, the numbering can be set up per project or per sheet.

02:09

Most projects require you to do this per sheet because different sheets may have different revisions.

02:14

You may issue one set of drawings, but not another set from the same project.

02:19

A bit further down, you can see we have our numbering options.

02:23

In these particular projects, I'm using alphanumeric.

02:26

And you can see here that we can then derive a sequence for our alphanumeric numbering.

02:30

So I'm starting off with a dash and then we're going through A, B, C, D, and so on.

02:35

And of course you'll notice here, if we want to we can remove letters, such as I or perhaps O from the revision sequence.

02:43

And then here, we have an option to set an arc length.

02:47

So when we create a revision cloud, we'll use the arc length specified here.

02:52

Ok, let's go ahead and add a new revision.

02:54

So I'm going to click on "Add", and our intention here is we've moved this wall, this blockwork wall,

02:60

and we need to add a revision and mark the drawing as such.

03:04

So here we can set a date. So we'll have that a day after the original change.

03:10

We can then put a description in, so here I'm going to say, moved blockwork wall 6 inches to right.

03:20

And here, you can see the Show is set to Cloud and Tag.

03:24

So let's go ahead and say "OK".

03:28

And if we look at the revision schedule, we'll see that we're still on first issue.

03:31

In order to get this new revision to appear in our revision schedule, we must cloud it.

03:38

So we'll zoom into the element that's changed, which is this blockwork wall here.

03:42

We'll select the Annotate ribbon and select "Revision Cloud".

03:47

In the Properties palette, we have something called a sequence, and this is where you decide what revision your cloud refers to.

03:54

So here, it's going to refer to the revision we've just created, which is Moved Blockwork Wall.

04:02

On the Context ribbon, you can see that we can decide on the type of geometry we're creating for a revision cloud.

04:07

In this case, it will be a simple rectangle, and will then cloud around the wall or the element that's changed.

04:14

Let's go ahead and select Finish Edit Mode.

04:18

So the revision cloud is now created.

04:21

And if we take a look at the revision table, you can see that it's added our new revision through.

04:26

Also, if we have a look at the current revision on the sheet, it's now changed to Revision A.

04:35

When working with a number of sheets and revisions, it can be quite useful to see these in a tabular format.

04:41

So we can create a schedule from these.

04:44

On the View ribbon, select Schedules pull-down and then click "Sheet List".

04:50

In the Sheet List Properties dialog box, I can take the available fields on the left and add them across to the schedule fields on the right.

04:57

So I'm going to begin here by taking in the sheet number, the sheet name,

05:02

will then take the current revision, the current revision date, and then when it's been issued.

05:11

I can then click "OK".

05:13

And you can now see that we have our sheet list.

05:16

Now from this sheet list here, it's very easy to filter the schedule based on whether the sheets have been issued or not.

05:22

Also, I can very clearly see the revisions and what state they're at.

05:27

If I want to, I can now open up another sheet, such as this one here.

05:31

And then of course, I can drag and drop that sheet list directly onto the drawing sheet, and that can form part of the drawing package.
