Use this module to import AutoCAD blocks into Block Explorer libraries
You begin by selecting from block sources:

There are three methods you can choose from to import
blocks into Block Explorer:

selected folder with all subfolders and dwg files. Selection is displayed as
folder tree in the left pane. 
To preview folder contents before they are
collected into library click on its folder node. To deselect a block uncheck its
box.
When this method is used Block Collector will try to determine
Destination and will prompt user to confirm it.
When there
are blocks available for collection and destination folder is selected to start
collection process click
button.
If you want Block Collector to include all folders click top folder
before starting block collection process.
Block Collector will process
one folder at a time and display collection results after each
folder.
You can interrupt collection process at any time by clicking
button
To finish collecting selected folder click
button again.
To resume
collecting whole tree select top node (in our example Test) and click
button.
When processing large amount
of blocks Block Collector performance degrades due to AutoCAD not clearing its
memory cache.
You can clear AutoCAD cache and improve performance by
clicking
button. Block Collector will
restart AutoCAD and will resume processing without any data loss.
If you
decide to exit Block Collector and not all selected blocks were collected you
will be prompted:
