How to Ask Better SOLIDWORKS API and SOLIDWORKS PDM API Questions
By Amen Jlili, Founder and Technical Director, Blue Byte Systems Inc.
Every day, developers, CAD administrators, and engineers ask questions about the SOLIDWORKS API and SOLIDWORKS PDM API. Some questions are answered in minutes, while others require several rounds of follow-up because important information was left out.
Whether you’re asking on CADOverflow, the SOLIDWORKS forums, Stack Overflow, AI tools, or reaching out to Blue Byte Systems directly, taking a few extra minutes to prepare your question will usually lead to a faster and more accurate answer.
Start With the Problem
Before posting code, explain what you’re trying to accomplish.
For example:
I need to automatically rename released drawings based on a company naming convention.
is much more helpful than:
Why doesn’t
RenameFile()work?
When people understand your goal, they may recommend a simpler, more reliable, and easier-to-maintain approach.
Tell Us About Your Environment
Whenever possible, include:
-
SOLIDWORKS version
-
SOLIDWORKS PDM Professional version
-
Windows version
-
Programming language, such as VBA, C#, or VB.NET
-
Whether you’re writing a macro, add-in, task add-in, or standalone application
-
Whether you’re using the SOLIDWORKS API, SOLIDWORKS Document Manager API, or SOLIDWORKS PDM API
These details immediately eliminate many possible causes.
Include the Complete Error
Instead of saying:
It doesn’t work.
Tell us:
-
What you expected to happen
-
What actually happened
-
The complete error message
-
The line where the error occurs
-
Whether it happens every time or only under certain conditions
Good technical support starts with good information.
Share a Minimal Reproducible Example
Large projects are difficult to review. Reduce your problem to the smallest amount of code that reproduces the issue.
A good example should:
-
Compile successfully
-
Remove unrelated code
-
Focus on one problem
-
Be easy for others to understand
You are a rockstar if you include everything in a public GitHub repository that other developers can clone, build, and run.
This may include:
-
Source code
-
Sample files
-
Setup instructions
-
Required references
-
SOLIDWORKS or PDM version details
-
Clear steps to reproduce the problem
A complete public repo removes guesswork and makes it much easier for others to help.
Include Sample Files When Necessary
Many SOLIDWORKS API issues depend on the model itself. Many SOLIDWORKS PDM API issues depend on the vault configuration.
If possible, include:
-
Sample parts
-
Assemblies
-
Drawings
-
Workflow information
-
Data card variables
-
Folder structure
-
Screenshots
-
Sample vault data
Sometimes a single sample file answers questions that hundreds of lines of code cannot.
Explain What You’ve Already Tried
Tell people what you’ve already tested.
For example:
-
API methods you’ve attempted
-
Documentation you’ve followed
-
Whether the code works on another model
-
Whether it only fails inside PDM
-
Whether the problem occurs for every user
This prevents duplicate suggestions and helps narrow down the real issue.
SOLIDWORKS API Questions Require Context
The SOLIDWORKS API is context-sensitive.
When asking a question, mention things such as:
-
Part, assembly, or drawing
-
Open or closed document
-
Active configuration
-
Display states
-
Selection state
-
Rebuild status
-
Macro or add-in
-
Export operation
-
Event being used
Small details often make a big difference.
SOLIDWORKS PDM API Questions Require Vault Context
For SOLIDWORKS PDM API questions, tell us:
-
Is the file checked in or checked out?
-
Is the file cached locally?
-
What workflow state is the file in?
-
Which event or transition triggers the code?
-
Does the issue happen for one user or everyone?
-
Are you writing a PDM add-in, a task add-in, or an external application?
Many PDM problems are related to permissions, workflow state, or vault context rather than the API itself.
Use AI as a Tool, Not a Replacement
AI tools like ChatGPT, Claude, and Gemini can be excellent assistants for SOLIDWORKS API and SOLIDWORKS PDM API development. They can explain concepts, generate sample code, help debug errors, and suggest different approaches.
However, many AI models are trained on publicly available information, including forum posts, blog articles, GitHub repositories, and documentation. Not all of that information is correct. Some examples are outdated, some apply only to older versions of the API, and others may be incorrect or incomplete.
Use AI to accelerate your development, but always verify the code it generates against official API documentation and test it in your own environment. Understanding the fundamentals of the SOLIDWORKS API and SOLIDWORKS PDM API allows you to recognize when AI is giving good advice and when it is confidently providing the wrong answer.
When asking AI for help, the same principles in this guide apply. Provide your SOLIDWORKS version, PDM version, programming language, relevant code, error messages, and a clear description of what you’re trying to accomplish. The more context you provide, the better the answer is likely to be.
Think About the Real Problem
Sometimes the question being asked is not the real problem.
For example:
How do I select this face by coordinates?
The real question may be:
What is the best way to identify this face?
Those questions can lead to completely different solutions.
Don’t be afraid to explain your overall objective. Someone may suggest a much better approach.
Beginner Questions Are Welcome
The SOLIDWORKS API has a steep learning curve.
It involves COM objects, configurations, references, events, rebuilds, file management, workflows, permissions, and many version-specific behaviors.
Nobody becomes an expert overnight.
Clear beginner questions are always welcome.
