Step-by-Step Guide to Getting Your SOLIDWORKS SDK ID

Alright, let's get down to business. Here's a step-by-step guide to finding your SOLIDWORKS SDK ID. Don't worry; it's not as scary as it sounds. Just follow along, and you'll have your ID in no time.

Step 1: Open the SOLIDWORKS API Help

The easiest way to find your SDK ID is through the SOLIDWORKS API Help. Here’s how:

1. Launch SOLIDWORKS: Fire up your SOLIDWORKS installation. The SOLIDWORKS application must be open.
2. Access API Help: Go to Help > SOLIDWORKS API Help. This will open the SOLIDWORKS API Help documentation. Navigating to SOLIDWORKS API Help is the first step.

Step 2: Navigate to the COM Category

Once the API Help is open, you need to find the COM category. Here’s how:

1. Check the Contents Tab: In the API Help window, look for a Contents tab on the left side. The Contents Tab is important.
2. Find the SOLIDWORKS Object Model: Look for a section titled "SOLIDWORKS Object Model" or something similar. Expand this section. The SOLIDWORKS Object Model section is what you need.
3. Locate the COM Category: Within the SOLIDWORKS Object Model, find the "COM Category" topic. This is where you'll find the information you need. Finding the COM Category is crucial.

Step 3: Find Your SDK ID

In the COM Category topic, you should find a list of COM classes and their corresponding IDs. Look for the main SOLIDWORKS application class. The ID next to it is your SDK ID. Here’s what to look for:

1. Identify the SOLIDWORKS Application Class: Look for something like "SldWorks.Application" or "SOLIDWORKS.Application.xxxx", where "xxxx" is a version number. The SOLIDWORKS Application Class is what we need.
2. Find the Class ID: Next to the SOLIDWORKS application class, you should see a Class ID (CLSID) listed in the format {xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx}. This is your SDK ID! The Class ID (CLSID) is your SDK ID.

Step 4: Copy and Save the SDK ID

Now that you've found your SDK ID, make sure to copy it and save it somewhere safe. You'll need it later when you're developing your applications or add-ins.

1. Copy the ID: Select the entire SDK ID string and copy it to your clipboard.
2. Save the ID: Paste the ID into a text file, a document, or your code editor. Make sure to label it clearly so you know what it is. Saving the SDK ID is important for later use.

Alternative Methods

If you're having trouble finding the SDK ID using the API Help, here are a couple of alternative methods you can try.

Method 1: Using the Registry Editor

Warning: Messing with the Windows Registry can be risky if you don't know what you're doing. Make sure to back up your registry before making any changes. I'm not responsible for any damage to your system.

1. Open the Registry Editor: Press Win + R, type regedit, and press Enter.
2. Navigate to the SOLIDWORKS Key: Navigate to HKEY_CLASSES_ROOT\SldWorks.Application\CLSID. You might need to adjust the path depending on your SOLIDWORKS version. Navigating to the SOLIDWORKS Key in the registry is key.
3. Find the SDK ID: In the right pane, you should see a value named (Default). The data for this value is your SDK ID. Finding the SDK ID in the registry is what you are after.

Method 2: Using a Visual Basic Script

You can also use a simple Visual Basic Script (VBScript) to retrieve the SDK ID. Here’s how:

1. Open Notepad: Open a new text file in Notepad.
2. Enter the Script: Copy and paste the following script into the file:

Set objSWApp = CreateObject("SldWorks.Application")
WScript.Echo TypeName(objSWApp)

3. Save the File: Save the file with a .vbs extension (e.g., getSDKID.vbs). Saving the file with a .vbs extension is crucial.
4. Run the Script: Double-click the file to run it. A message box will appear, displaying the type name of the SOLIDWORKS application object. This type name is essentially your SDK ID.

Troubleshooting Common Issues

Sometimes, things don't go as planned. Here are some common issues you might encounter and how to fix them.

• API Help Doesn't Open: If the SOLIDWORKS API Help doesn't open, make sure that the API documentation is installed. You might need to modify your SOLIDWORKS installation to include the API documentation. Ensuring the API documentation is installed is vital.
• Cannot Find the COM Category: If you can't find the COM Category in the API Help, try searching for it using the search function within the API Help. Sometimes, the location of the COM Category can vary depending on the SOLIDWORKS version. Using the search function can help.
• Registry Key Not Found: If you can't find the SOLIDWORKS key in the Registry Editor, make sure you're using the correct path. The path might be slightly different depending on your SOLIDWORKS version. Double-checking the registry path is a good idea.
• Script Doesn't Work: If the VBScript doesn't work, make sure that Windows Script Host is enabled on your system. Also, ensure that you have the correct version of SOLIDWORKS installed and that the script is using the correct application name. Making sure Windows Script Host is enabled is important.

Using the SDK ID in Your Projects

Okay, so you've got your SDK ID. Now what? Here's how you can use it in your projects.

Creating a SOLIDWORKS Application Object

The first step is to create a SOLIDWORKS application object using the SDK ID. Here’s how you can do it in different programming languages.

• C#:

Type swType = System.Type.GetTypeFromProgID("SldWorks.Application.28");
SldWorks.SldWorks swApp = System.Activator.CreateInstance(swType) as SldWorks.SldWorks;

• VB.NET:

Dim swType As Type = System.Type.GetTypeFromProgID("SldWorks.Application.28")
Dim swApp As SldWorks.SldWorks = CType(System.Activator.CreateInstance(swType), SldWorks.SldWorks)

• VBA:

Dim swApp As Object
Set swApp = CreateObject("SldWorks.Application.28")

Replace "SldWorks.Application.28" with your actual SDK ID. Remember to replace the placeholder with your actual SDK ID.

Connecting to a Running Instance of SOLIDWORKS

Sometimes, you might want to connect to an already running instance of SOLIDWORKS. Here’s how you can do it:

• C#:

SldWorks.SldWorks swApp = System.Runtime.InteropServices.Marshal.GetActiveObject("SldWorks.Application.28") as SldWorks.SldWorks;

• VB.NET:

Dim swApp As SldWorks.SldWorks = CType(System.Runtime.InteropServices.Marshal.GetActiveObject("SldWorks.Application.28"), SldWorks.SldWorks)

Replace "SldWorks.Application.28" with your actual SDK ID. Don't forget to replace the placeholder with your actual SDK ID.
