Purge

Remove unused objects from the drawing.

The Purge Unused Objects window lists all the objects in the drawing that are unused.

Select the objects you want to remove from the drawing.

After a purge operation, new objects may appear in the unused objects list. These are objects that have become not referenced after the last purge operation.

This action cannot be undone.

Procedure

1. The Purge Unused Objects list displays and lists all the objects in the drawing that are not referenced by any entities or other objects in the drawing.

2. To purge only selected objects, you can select the objects from the objects list by clicking them. Alternatively, use press and hold [Shift] while you select a range of objects, or press and hold [Ctrl] while you select individual objects.

3. Specify the action you want to take:

• Click Purge Selected to remove the selected objects from the drawing.

• Click Purge All to remove all unused objects from the drawing.

• Click Purge Duplicate Entries to remove all duplicate entries from the drawing.

This function allows you to clean up the drawing by removing invalid geometry elements and fixing errors in styles and style references. Errors that can be detected and fixed are:

• Zero-length lines and polylines

• Zero-radius arcs and circles

• Empty text entities

• Hatches with no boundaries

• Entities with invalid coordinates

• Bad layer/block/style references e.g. a text entity that references a text style that does not exist in the drawing

• Bad layer/block/style names

1. In the Purge dialog, click Fix drawing....

2. You are prompted to select which errors you want to detect/fix.

3. Click Select All to enable all options, or select options individually bu selecting the appropriate checkboxes.

4. Click OK to run the Fix drawings function. If you have a very large drawing the function may take a few seconds to run.

5. A message will inform you of how many entities were removed from the drawing.

6. More detailed results will be sent to the Output Bar.
