Multiple drawings can be automatically created from a typical drawing or updated based on a control file that can be created with an Excel template. Make the changes in Excel and let the program do all the work for you. This is a real time saver if you need to make adjustments on hundreds or thousands of drawings.

Optionally an AutoLISP file (*.lsp;*.vlx;*.fas) can be loaded for each drawing. Each drawing can use a separate AutoLISP file if needed. This gives you almost unlimited flexibility when it comes to what task you want to automate.

Example of usages: Add a stamp block; insert a title block; update text or attributes in the title block; insert text, block or xref; change text or attribute values and more. Change all external references (xrefs) from absolute paths to relative paths for archive purpose. Find and replace attribute or text values.

Bulk updating AutoCAD or BricsCAD drawings in most any way that you would like.

If you have an idea of what you want to automate but don't know how to realize it, contact us for a solution.


AutoGen creates new drawings based on one or more template drawings based on the control file. In the process text, mtext and block attribute values can be changed individually on each new drawing.

It is possible to change only a part of the text string. If the template drawing contain the text "SHEET #sheetno#" it can be updated to for example "SHEET 1" by specifying #sheetno# as the text to change.

Depending on your computer performance and the complexity of the drawing you can generate around 100 drawings in just 60 seconds.

AutoGen Excel template

AutoGen has been used by customers creating instrumentation drawings, loop diagrams (loop drawings), schematics in an automated way based on data in a spreadsheet.


AutoIns inserts text, blocks or xrefs into drawings based on the control file.

These are the properties that can be set using the control file.

Object Property
General Layer
General Color
General Rotation
General Insertion point X
General Insertion point Y
General Insertion point Z
General Layout
General UCS (Current, World, Named)
Block/Xref Path+Name
Block/Xref Scale X
Block/Xref Scale Y
Block/Xref Scale Z
Block Explode (Yes/No)
Xref Reference type (Attach/Overlay)
Xref Path type (Full/Relative/No)
Text Style
Text Justify
Text Height
Text Width factor
Text Obliquing

In case you want to insert for example a circle or more complex geometry you can make a block of it and the insert it with the Explode property set to Yes.

AutoIns Excel template


AutoUpd updates existing drawings based on the control file.
In the process text and attribute values can be changed individually on each new drawing.

It is possible to change both the whole text string or only a part of the text string. If the template drawing contain the text "SHEET #sheetno#" it can be updated to for example "SHEET 1" by specifying #sheetno# as the text to change.

AutoUpd Excel template

It is also possible to update text found at a location by defining a rectangle with two coordinates. This is for example useful if a title block contains mtext or text objects not being part of a block object.

With the Import from drawings functionality you can get block and attribute information from one or many drawings.

Example on how to search and replace attribute values or text.

Control file creation

The copy button can be used to copy sample files that are in (%appdata%\Autodesk\ApplicationPlugins\JTBW-CADAutomationTools.bundle\Contents\JTB CAD Automation Tools) to the C:\JTB CAD Automation Tools folder.

This shows an example how to use AutoGen and the steps are similar for the other commands.

Open AutoGenTemplate.xls

Specify path and name for the drawing to be created as well as the path and name for the template to be used.

Use a button to select and populate the template sheet with the path and name for the drawings.

Use a button that automatically save the Excel template to the correct format.

The Control file should be in TXT tab delimited format.
Start with AutoGenTemplate.xls and when ready save as Text (Tab delimited) (*.txt).

Excel 2007 and newer versions supports more than 256 columns. Make sure to save the Excel file to the XLSM format that allows macros.


Recommendation is to close all drawings and start a new empty drawing.
Start with the commands AutoGen, AutoIns or AutoUpd.
The first time you may be asked for the location of program file.
When asked for control file browse for and select the control file to be used.

Vault tips:

Check out a folder to Work Space.
Run the tools on the files.
Check folder back into vault.

Tips and tutorial from the blog:

**IGNORE** can be used as a value if you don't want JTB CAD Automation to affect the value for a specific combination of drawing and attribute/text.

Trouble Shooting

If the program is not working as expected run "Reset JTB CAD Automation Tools.reg" found in the installation folder and merge it to the registry to reset the paths.

Check AutoCAD's or BricsCAD's command line when you start a new drawing and see if there are some errors. This can cause the program to halt. One indication on this problem is that AutoGen produces the new drawings but does not update them.

If you have old templates they might not be compatible with most recent template format. Check that they are matching.

Contact us for further support.

Known limitations

      • When having more than 1 of the same block in a drawing the AutoUpd command will not be able to update each unique instance of the block's attributes. If you have a need to have this fixed please contact us.
      • Search and replace is case sensitive
      • Wish: add support for handling dynamic blocks and their special properties
      • Wish: add support for handling dynamic blocks for AutoUpd Excel sheet "Import from drawings" function
