Export a CAD file

00:07

INSTRUCTOR: Sometimes, your extended team

00:09

needs digital files instead of printed sheets.

00:11

If they're using Revit, you can simply

00:13

share your model with them.

00:14

If they need a PDF, then simply print

00:17

but choose a PDF printer instead of a physical device.

00:20

If they're using AutoCAD or some other similar software,

00:24

then you can export to DWG or other popular file formats.

00:28

So let's look at the process to export to DWG.

00:32

We'll go to the File menu and then highlight Export.

00:35

And then up here near the top, you'll see CAD Formats.

00:38

And notice that there are four different formats

00:40

that you can export to.

00:41

I will choose DWG.

00:44

At the top, there's a dropdown for Export Setups.

00:47

So optionally, you can save custom configurations,

00:50

and they will show up in that list.

00:52

To edit the setup, you use this Browse button right here.

00:55

And that will take you to a rather extensive dialog where

00:58

you have lots of settings that you can configure

01:00

to create an export setup.

01:03

Now, the one that's probably the most extensive

01:06

is the Layers tab.

01:08

Most CAD files are organized into layers.

01:10

And you can see here that all of the Revit categories

01:14

get mapped to a layer in AutoCAD and a corresponding color

01:19

number.

01:19

Now, you can go through this list

01:22

and customize it object by object, layer by layer

01:24

if you wish.

01:25

Or you can use one of the pre-built industry

01:28

standards that appears here on this dropdown.

01:31

So feel free to explore this and make any customizations

01:35

that you like.

01:36

Now, you can do similar things on the Lines tab

01:38

to map the line styles in Revit to line types in AutoCAD.

01:43

Or the patterns in Revit to hatches in AutoCAD,

01:46

and the text and the fonts.

01:48

And how do you want to treat colors?

01:49

And what do you want to do with 3D geometry

01:52

when you're exporting 3D views?

01:53

How do you want to treat your units?

01:55

And finally, on the General tab are

01:57

some miscellaneous settings, perhaps the most important one

01:60

being which file format do you want to export to.

02:04

So make sure you communicate with your recipient

02:06

and find out which version of AutoCAD

02:07

they're planning to open these files in.

02:09

And then choose an appropriate format from the list.

02:12

Now, I'm not going to make any changes to the export setup,

02:15

so I will simply cancel that.

02:16

But you're welcome to make whatever changes you like.

02:19

Next, you want to go to the Export dropdown here.

02:22

And you have two choices as far as

02:24

what's going to actually be exported from the Revit model.

02:28

Now, it defaults to the current view and sheet only.

02:30

So whatever you have open here in the background-- in my case,

02:34

this elevation sheet--

02:36

that's what's going to be export.

02:37

Otherwise, you can choose the second option,

02:40

and that gives you another dropdown.

02:42

So here you have some additional choices

02:44

that let you look at the views and/or the sheets that

02:47

are in your model.

02:48

If you go to the very bottom here,

02:49

All Views and Sheets in the Model, this

02:51

will give you a complete list of every view and every sheet

02:55

that's on the project browser.

02:57

And then you can check the ones that you

02:59

want to include in the export.

03:01

So let's say that I wanted to include

03:03

a floor plan and this elevation sheet, and I'll click Next.

03:08

You want to browse to a folder where

03:09

you want to make this export to, give it a file name prefix.

03:14

Naming will default to automatic naming,

03:16

which will use that prefix when creating the name.

03:19

And then finally, at the bottom is perhaps

03:21

what I think is the most interesting setting.

03:24

It's a checkbox that says Export Views on Sheets and Links

03:29

as External References.

03:30

So what this means if you consider this sheet

03:33

in the background is I would actually get three DWG files--

03:36

one for the sheet itself and then one

03:38

for each of the viewports that will be xrefed back

03:41

into that main sheet.

03:43

So assuming that you're satisfied with all the settings

03:45

here, you can click OK, and it should only

03:48

take a moment or two for the export to be performed.

03:51

Now, if you have a copy of AutoCAD,

03:53

you are welcome to open up the results and take a look.

03:57

So here I have the elevation sheet with its two viewports

04:01

containing the two xrefs.

04:03

And here's one of those xrefs opened up independently.

Exercise 1–Export a CAD file

Sometimes your extended team needs digital files instead of printed sheets. If they are using Revit, you can share your model with them. If they need a PDF, simply print but print to PDF instead of a physical print device. If they are using CAD, you can export a DWG.

Catch-up file completed to this point: 21_Medical Center_Export.rvt

Export Setup

There are lots of settings you can configure to export to DWG.

  1. From the File menu, choose: Export>CAD Formats>DWG.
    Export to CAD formats.
  2. At the top of the dialog, click the browse button next to the Export Setup list.
    Edit the Export Setup.
  1. Click through each tab and scan the various settings.

The layers tab configures how Revit elements will be organized onto DWG layers. There are several industry standard layer schemes such as the American Institute of Architects and British Standard 1192.

You can also configure line types, hatch patterns, text and fonts, colors and units. You can even indicate if 3D elements should export as solids or meshes. (Note to create 3D elements in AutoCAD you must export from a 3D view).

The file format for your recipient is on the General tab. Choose the version of AutoCAD they have.

  1. Click Cancel once when you are done exploring to close the “Export Setup” dialog and return to the “DWG Export” dialog.

Export a DWG

You can export sheets, views or both.

  1. In the “DWG Export” dialog, on the right, click the Export drop-down and choose: <in-session view/sheet set>.

The “Show in list “drop-down will appear.

  1. From the “Show in list “drop-down choose: Sheets in the Model.
  2. From the list that appears, check the sheet(s) you wish to export (see Figure 21–3).

If you have been following along, you should have at least one sheet. But you may have more. Feel free to check as many as you wish.

Choose the sheet(s) that you wish to export

In cases where you have many sheets, there are icons at the top of the list that you can use to make a saved list of sheets for later retrieval.

  1. Click Next.
  2. In the “Save to Target Folder” dialog, make sure that “Export views on sheets and links as external references” is checked, accept the default name and then click OK (see Figure 21–4).
    Browse to a folder, configure settings and OK to complete the export.

This option creates a DWG with a titleblock in paper space and viewports for each view on the sheet. The contents of each view are separately exported as their own DWG files and are XREFed back to the sheet file.

  1. If you have AutoCAD, feel free to open the file(s) and check the results.
