This tutorial will guide you through the steps on how to use ACAD_db to synchronize AutoCAD attribute values in a title block with a database. Use this tutorial together with the ACAD_db documentation. Download ACAD_db_example.zip to follow along and test for yourself.

List the title block to find the following information that needed.

Block Name: "ISO A1 title block"
Attribute tags:
CHECKED_BY
OWNER
DESIGNED_BY
FILENAME
DRAWING_NUMBER
APPROVED_BY_DATE
TITLE
DATE
EDITION
SHEET
SCALE

Copy the Access database template ACAD_db_EmptyTemplate.mdb that is included with ACAD_db and name it ACAD_db_Sheets.mdb. Because read and write access is needed for the MDB file it can be a good idea to not save it in the Program Files folder structure as it is often restricted to read-only.

Copy ACAD_db_samples.UDL and name it ACAD_db_Sheets.UDL and place it in AutoCAD’s Data Sources Location (Options>Files). Double click on the file and edit the path to the location of ACAD_db_Sheets.mdb.

Open ACAD_db_Sheets.mdb and then table JTBW_AttSync.

Add the information about the title block. The attribute DRAWING_NUMBER contains a field so SyncDir is set to DWGtoDB while other fields can be synchronized both ways.

 
In the column DBConnection there is the name of the data source followed by the table name followed by the field name separated with an exclamation character.

Here is what the table TitleBlock look like. Notice the mandatory fields DBID, DWG, Handle and BlockName.

In AutoCAD make sure JTB.ACADdbMgd.dll is loaded using one of the options specified in the documentation.

Run the AcDbSettings command and specify the name of the data source to be used.

For each drawing that should be synchronized with the database run the command AcDbMake to make the connection.

Make changes to the title block.

Save and Close the drawing. Open the database and verify that the table TitleBlock is populated with the attribute values.

Make a change in the database on one or many values.

The changes are seen when the drawing is opened.

Any type of block with attribute can be synchronized with ACAD_db in this same manner. There can be for example one title block on multiple layouts in one drawing or it can be blocks that represent building elements or schematic symbols. The choice is yours.
