At some situations we all face some situations like Drawings won’t open, Application closes unexpectedly when trying to modify an object or entity or some power fluctuations

We know these situations can be frustrating, but ActCAD offers these tools to help:

Backup and perform an automatic save of a drawing:

Recover Drawing

Autosave Drawing Every Mark to create a backup of the drawing at specified time intervals. The default is 15 minutes; selecting a value of 0 minutes is the same as turning automatic save off. The file is saved in the folder specified in Options > Paths/Files for Temporary Files, with the file extension specified in the File Extension box (by default, .SV$).

Back Up to BAK File when Saving Drawings Mark to save an older version of a drawing file with a .bak extension each time the drawing is saved. (This setting corresponds to the ISAVEBAK system variable.) .

When Drawings Close Choose how to treat autosave and backup files when the program or drawings close. (This setting corresponds to the AUTOSAVERETAIN system variable.)


Displays the Open Drawing dialog box so you can open a drawing that you suspect is damaged, for example, a drawing damaged during a power outage or system crash. The drawing file is restored as much as possible with its original contents.

You can recover .dwg, .dwg, .dxf, and .dwt files with this command. To find files on another drive, use the Look In list. You can navigate to find the file name you want, or type the name into the File Name field.

If the AUDITCTL system variable is set to On and errors are found in the file, an ASCII file is created that describes the errors that were fixed in the file. The ASCII file is saved in the same folder as the recovered drawing, and has the same name as the drawing file, but with an .adt file extension.


Cleans the drawing file of unused drawing elements. Use Purge to remove blocks, groups, layers, linetypes, print styles, shapes, text styles, multiline styles, dimension styles, or materials from Explore Materials, that you have defined but are not using in the drawing. Purging can significantly reduce the drawing file size.

You can also purge unused registered applications, which display in the list if the Experience Level is set to Advanced on the Options - General tab.

Linetype definitions are purged only from the drawing; the definition in the icad.lin file is not purged.

Drawing Items To display only the items that can be purged, select View Items You Can Purge; to display only the items that cannot be purged, select View Items You Cannot Purge. The list displays the appropriate items depending on your selection.

Confirm Each Item to be Purged Select to display a prompt before an element is purged to confirm or cancel.

Purge Nested Items Select if there are nested blocks in the drawing and you want to purge all levels at one time. For example, if this option is not selected and say you create a block from a circle and insert two instances of this block into your drawing. Next, you create a block that consists of these two circle blocks, and you insert the new block into the drawing. If you delete the new block, you will still have an unused, nested block in the file. If you purge the file, the first block with the single circle remains in the file. You must use the Purge command again for as many times as there are levels of nested blocks. If one or more elements that you want to purge cannot be found in the file, a message is displayed listing those elements.

Automatically Purge Orphaned Data Mark to automatically remove obsolete .dgn linestyle data when the dialog box is opened.

Purge Click to purge selected items.

Purge All Click to purge all unused elements.
