JTB ACA_db

About

Make use of AutoCAD Architecture, AutoCAD MEP, AutoCAD Map 3D or AutoCAD Civil 3D more fully in your BIM process. Property Set values can automatically be updated back and forth to one or many external databases. If you make changes to the Extended Data values within a Property Set they can be synchronized back to the external database. Any Property in a Property Set Definition can be exported and all editable Properties can be imported.

ACA_db will improve the BIM process and experience and will improve quality of your data and remove redundancy and conflicts of data.

Documentation

Installing

For the version 5.0 or later run the installer.

Activation

See activation instructions here: JTB World Apps Licensing.

Usage

Commands:

	AcDbSettings	Choose an ACA_Db master database to sync. This needs to be done once per drawing. Your drawing should be saved after setting.
	AcDbMake	Register current drawing to Database to enable sync attributes data. This needs only to be done once per drawing.
	AcDbIn	Sync values from database based (on sync dir) to Property Set values in the current drawing.
	AcDbOut	Sync Property Set values in the current drawing to the connected database.
	JTBW_ACTIVATE_APPS	Open Activation Form to activate the app. This command is available in command line only. See activation instructions here: JTB World Apps Licensing.

This app updates Property Set values back and forth to one or many external databases. If you make changes to the values within a Property Set they can be synchronized back to the external database. Any Property in a Property Set Definition can be exported and all editable Properties can be imported.

Open sample drawing in the app folder "C:\ProgramData\Autodesk\ApplicationPlugins\JTB-ACA_db.bundle\Contents\ACA_db_samples_2013.dwg"

The app needs a data link UDL file. Run AcaDbSettings command then click "Browse" button to choose one. There are 2 sample UDL files that included in the app, one for AutoCAD 32-bit and one for AutoCAD 64-bit. Both link to the sample "ACA_db_samples.mdb" file

Select the proper UDL, then click OK.

Run AcaDbMake command to register the drawing to the selected database.

Once success, you can use AcaDbIn and AcaDbOut commands to sync Propert Values.

Setup your own database

Run AutoCAD native command "DBCONNECT" to create a data link UDL file. Alternatively copy and modify an existing UDL file or create one from scratch. (see screenshots below)

Right click on Data Sources and select Configure Data Source…

Give it a name.

Specify the database provider:

+ For 32-bit AutoCAD use Microsoft Jet 4.0 OLE DB Provider.

+ For 64-bit AutoCAD use Microsoft Office 12.0 Access Database Engine OLE DB Provider.

Make the Connection by selecting the database to use.

Then run AcaDBSettings command again to choose it.

You can also double click on the UDL file directly in Windows Explorer to edit the properties.

Database structure

The main database must contain the tables JTBW_Files, JTBW_PropertySets and JTBW_Properties.

Put the database in another folder than where this app is installed and make sure it is backed up.

The other tables that contain the actual data can be located in the same or in one or more other databases.

Program requires following mandatory tables in the database.

1. JTBW_Files (Column DWGNAME is mandatory)

This table can be manually populated otherwise the program will populate it automatically.

2. JTBW_PropertySets (Columns Property Set Name and Description are mandatory)

Manually enter the name of the Property Set Definitions in AutoCAD Architecture to be used. This value is case sensitive.

A description is optional.

3. JTBW_Properties (Columns ID, Property Name, Property Set Name, Description, DBConnection and IsDimensionInNumericFormat are mandatory)

Property Name must match an existing name in the specified Property Set Definition in AutoCAD Architecture. This value is case sensitive.

Property Set Name must match the name of the Property Set Definition in AutoCAD Architecture and also exists in the JTBW_PropertySets table. This value is case sensitive.

Description is optional.

DBConnection specify the name of the data source, table and column (field) separated with “!”. For example ACA_db_samples!WallObj!Length

IsDimensionInNumericFormat If yes, then dimensions are in numeric format. If no, then dimensions are in text format (feet & inches).

4. Any other tables stores property values (Columns DBID {AutoNumber data type and Long Integer size} , DWGNAME {Memo data type and long text string size} and HANDLE {Text data type with 255 field size} are mandatory).

These tables can also be in a separate database if there is a data source that identifies it.

Property Set Definitions and other notes

Use the command _AecStyleManager or Format menu to start the Style Manager.

Expand Documentation Objects on the left side and then expand Property Set Definitions.

Either an existing PSD can be used or a new can be created.

What makes a Definition to have the ability to be retrieving information from a database is that it is added to the database tables JTBW_PropertySets and JTBW_Properties.

Property set data type and database data type must be compatible.

A PSD must be linked to a single table.

An object must not have 2 or more records linked from same db link.

An object must not have 2 or more records linked from different db links referencing same table.

All automatic properties are considered as read-only. Such properties can sync to database but cannot sync from database.

ACA_db_samples.mdb
ACA_db_samples_2007.dwg or ACA_db_samples_2010.dwg or or ACA_db_samples_2013.dwg
ACA_db_samples.UDL
ACA_db_license.txt (sent by email from JTB World upon request)

Setup procedure (older versions than 5.0)

Place the DLL file in a single local folder.
For example C:\Program Files\JTB World\ACA_db .
Place also the license file ACA_db_license.txt in the same folder.
ACA_db_samples.UDL should be placed in the Data Links folder. The location is found easiest by using the command OPTIONS and Files>Data Sources Location within AutoCAD.
Place the MDB in a folder with read/write access.

The DLL needs to be loaded by your AutoCAD application and that can be done in different ways. Use one of the following options.

Use the command NETLOAD and select the DLL. This loads the command in the current session only.
Create a menu command, toolbar button, ribbon button or palette tool using CUI and force load it before running the command.
Macro or Command string:
^c^c(command "netload" "C:/Program Files/JTB World/ACA_db/JTB.AcaDbXMgd_18.dll") ACADBOUT;
Use one of the AutoLoad...reg files that can be provided. Double click on the file and accept to merge to the registry. This will make sure that the commands are available whenever you run AutoCAD.
Add the row below to your acad.lsp file so it loads automatically when AutoCAD starts.
(command "netload" "C:/Program Files/JTB World/ACA_db/JTB.AcaDbXMgd_18.dll")

Solution to the following error is to right click on the DLL file and click on Unblock.
