Clean up Civil 3D data prior to ACC migration

Clean up Civil 3D data prior to migrating files to Autodesk Construction Cloud (ACC).


00:03

Data cleanup prior to migrating your files into the Autodesk Construction Cloud is essential to ensure a smooth process.

00:11

Take a moment to review the recommended methods for data cleanup before you migrate a drawing to ACC.

00:19

To remove REGAPPS, perform a -PURGE.

00:22

Note that REGAPPS will return if included in a file with XREFs, so make sure to clean them all.

00:29

Simply type “-PURGE” on the command line and then “R” for REGAPPS.

00:36

Use the standard Purge feature to clean unused entities, such as layers, blocks, and line types, from your drawing.

00:46

Enter “PURGE” on the command line to access the Purge dialog.

00:51

Use the OVERKILL command and follow the prompts to clean up overlapping or duplicate drawing entities.

00:59

If you try these methods and still experience file issues, the Write block command,

01:04

or WBLOCK, transfers all drawing elements into a clean drawing.

01:08

In most cases, WBLOCK will address corrupt data issues;

01:14

however, in some rare cases, WBLOCK may not fully eliminate the corruption or may require rebuilding LandXML data.

01:24

Use the AUDIT command to evaluate the integrity of the drawing, as well as identify and fix errors.

01:31

As a best practice, run an AUDIT on your drawing daily to assess and fix errors early on, ensuring data integrity throughout your process.

01:41

Use RECOVER if, for example, you constantly crash on a specific file.

01:47

This will help repair and then open the damaged drawing.

01:51

You can also run RECOVERALL on a damaged drawing with attached XREFs.

01:57

Use the more advanced MAPCLEAN command on a file to delete duplicate data, weed polylines,

02:04

and eliminate zero-length objects, as well as other tasks.

02:09

The corresponding dialog includes many options to select and perform cleanup actions.

02:15

To save time, you can download and install the Drawing Purge add-in from the Autodesk App Store.

02:22

This add-in enables you to purge multiple drawings at the same time,

02:27

and offers numerous settings to help you manage data cleanup efficiently.

02:33

The Reference Explorer tool, part of Desktop Connector, allows you to visualize all referenced files in a dataset and their relationships.

02:41

Drag and drop a file from Windows Explorer into Reference Explorer

02:46

to precheck file references and to better understand the size and scope of a dataset.

02:52

In Reference Explorer, you can choose from three different Views, as well as multiple Graph Layout options,

02:58

to visualize your file relationships.

03:01

At the bottom of Reference Explorer, you can also view the number of files and the data set size, as well as any missing references.

03:10

Note that the files must be synced for references to display.

03:15

To sync files, in Windows Explorer, right-click the host file and select Sync or Always keep on this device.

03:24

In Civil 3D, you can repair broken shortcuts or replace drawing objects with data shortcuts.

03:32

In this image, numbers identify the locations of relevant commands on the ribbon and in the Data Shortcut Manager,

03:39

with the corresponding actions on the left.

03:43

On the ribbon, select the Manage tab to access commands to Validate Data Shortcuts, Synchronize References,

03:51

and Manage Data Shortcuts.

03:54

To replace drawing objects with data shortcut references, in the Data Shortcut Manager,

04:00

ensure that Show only broken data shortcuts is deselected.

04:05

Finally, here are some additional recommendations for reducing file load times in ACC:

04:11

A large number of annotation scales can increase file load times, both for the file itself and for any files that reference it.

04:19

When the Annotation Scale Warning appears, select Yes to reset the scale list.

04:26

Then, do a PURGE on your drawing.

04:29

Additionally, always save DWG files in the 2018 format.

04:35

The converting process will be slowed down in Civil 3D when referencing a DWG with an older format.

04:43

Now, you know the data cleanup methods and recommendations that can help to ensure a smooth migration to ACC.
