We can use programming language C#, C++ ,Visual Basic and JAVA to automate PowerDesigner. But these languages are very complicated. It may take

a professional programmer days or weeks to get job down. In addition, we have to install Microsoft Visual Studio or Eclipse as development tool, which

is not always available to everyone.

Microsoft Powershell, by contrast, is simple, powerful and available to almost all Windows users. Powershell 2.0 is already installed  on Windows 7.

Plus a lot of automation solutions are already available in Powershell community.

I'm going to separate the topic in three parts:

Part one        Create a model

Part two         Emulate mouse and keyboard to control Powerdesigner GUI

Part three      Automate Powerdesigner Portal Server login process

In this article, I'm going to work on part one.

I'm on Windows 7 64bit with PowerDesigner 16.5.4 64bit.  I have not tested 32bit PowerDesigner.

First of all, for those who are unfamiliar with Powershell, go to Internet, search for Powershell, you'll get tons of information and tutorials.

Here we only need learn three commands:

new-object              this command allows us create a new object

add-type                we use this command to load external assembly files.

get-member           given an object, list all its member functions

Windows 7 64bit has both 32bit and 64bit Powershell installed. But by default, it runs 64bit version.
Let's start Powershell 64bit.

Click Start button. search for Windows PowerShell . Click the Windows PowerShell tile


Click Start button. Click Run...  Type powershell.  Click OK.

Powershell window pops up.

At command prompt, type or paste the following code and hit Return

$PowerDesigner = new-object -com powerdesigner.application

Powerdesigner starts.

In command prompt, type or paste the following code and hit Return

$Powerdesigner | Get-Member

The output lists all functions $Powerdesigner COM object owned.

   TypeName: System.__ComObject#{57c91ea5-68ef-4877-bb3e-757b12ecae55}

The list is very helpful. It tells user which function is available and for what purpose.

Next, in order to create a PDM we need load two Powerdesigner COM assemblies



By default, all PowerDesigner COM assemblies are located at PowerDesigner Home folder.

But you can move them to other place. In my case, I put them in D:\PD folder.
Type or paste the following code and hit Return:

add-type -path "D:\PD\Interop.PdCommon.dll"
add-type -path "D:\PD\Interop.PdPDM.dll"

The assemblies are loaded.

We want to create a PDM, which contains a table with a column.
Type or paste the code below. Don't forget hit Return.

$model=$PowerDesigner.createmodel([PdPDM.PdPDM_Classes]::cls_Model,"|DBMS=ORACLE Version 11g",0)
if ($model -eq $null )
  [Windows.Forms.MessageBox]::Show("Cannot create PDM")
  $ ="PDMexample"
  $model.code ="PDMexample"
  $tbl=$model.createobject([PdPDM.PdPDM_Classes]::cls_Table,"" , -1, $false)
  $tbl.Comment="Customer table"
  $tbl.Description="The customer table stores customer data"


A PDM with a table is created. It uses Oracle 11g as DBMS.

You can copy above code in notepad and save as, say CreatePDM.ps1(ps1 means Powershell script). In PowerShell prompt, go to the same folder where

CreatePDM.ps1 located, type


The program will do its job.

Attached is CreatePDM.ps1.

Enjoy coding!
