What the Letters Stand For
CSWP-API stands for Certified SOLIDWORKS Professional API. Each piece of the name carries weight. "Certified" signals a vendor-issued credential rather than a course completion certificate. "SOLIDWORKS Professional" places it in the SOLIDWORKS certification ladder aimed at working practitioners. "API" tells you the subject: the SOLIDWORKS Application Programming Interface, the object model that lets code create, read, and modify models, drawings, and assemblies.
In plain terms, the credential says that a person can write working automation against SOLIDWORKS, not just talk about it. If you are looking for a shorter explainer on the acronym itself, see What Does CSWP-API Stand For? and What Is CSWP-API?. For the broader program picture, CSWP-API Certification is the hub page.
Who Issues It and How It Is Delivered
The exam is governed by SOLIDWORKS and delivered through Tangix/VirtualTester. Candidates are directed to follow the current VirtualTester Web Client instructions. The older exam guide describes a legacy TesterPRO installation and crash-recovery language; the issuer's current browser-client and recovery instructions take precedence where the two differ.
Several delivery details shape what the credential means in practice:
- Non-proctored, online. You sit the exam on your own machine with your own working commercial or student SOLIDWORKS installation and your own Internet connection.
- Software minimum. SOLIDWORKS 2017 or later. That figure is a software minimum, not an exam version label; the live exam page and the linked sample guide are undated.
- No pausing. Once started, the exam runs on its clock.
Because the exam runs inside your own SOLIDWORKS environment, the credential implicitly certifies something practical: that you can get VBA code running against a real session of the software under time pressure.
The 18-Task, 10-Question Structure
The linked SOLIDWORKS Certification Exam Guide & Practice Test specifies 28 questions: 18 hands-on automation tasks and 10 multiple-choice questions. The exam totals 100 points, requires 70 to pass, and allows 120 minutes. The exam page confirms the two-hour duration and 70% passing grade.
| Element | What the issuer states |
|---|---|
| Total questions | 28 |
| Hands-on automation tasks | 18 |
| Multiple-choice questions | 10 |
| Total points / passing | 100 / 70 |
| Duration | 120 minutes, cannot be paused |
| Language focus | Visual Basic for Applications (VBA) |
The split matters. A majority of the exam is hands-on: you are expected to produce code that does something to a model, not merely recognize correct syntax. Multiple-choice items cover the conceptual side, such as how the object model hangs together and what a given call returns.

The 15 Objectives Behind the Meaning
The issuer lists 15 exam objectives, unweighted. The issuer also describes the task list as non-exhaustive, so no percentage weights or extra objectives should be assumed. Some drawing headings overlap, and they are retained here as written. The full breakdown lives in CSWP-API Exam Domains: Complete Guide to All 15 Content Areas; here is how they cluster in meaning.
Foundations: Understanding the API Object Model and Troubleshooting
Everything else rests on these two. The object model is the hierarchy from the SldWorks application object down through documents, features, entities, and their properties and methods.
- Know how to move from the application object to the active document and then to model-specific interfaces.
- Use API Help to find a method's signature, return type, and parameters rather than memorizing them.
- Understand the macro recorder's limits: it captures UI-level actions and often produces code that is brittle or incomplete, so recorded output is a starting point, not an answer.
- Troubleshoot by checking return values, null objects, and whether a selection actually succeeded.
Model Building: Part design automation, Sketch entities and dimensions, Feature creation
These objectives cover creating geometry through code.
- Add sketch entities and dimensions programmatically, then confirm the sketch solved as intended.
- Create features such as extrudes and cuts, paying attention to the parameters that control direction, depth, and end conditions.
- Verify results by traversing the feature tree rather than trusting that no error means success.
Navigation: Selection and traversal techniques
Much of automation is finding the right thing. Selection by name, by coordinates, or by walking the feature tree or component list is a recurring skill, and it is where many candidates lose time.
- Practice traversing features, faces, and edges and testing types before casting.
- Learn how selection marks and select data affect calls that consume the current selection.
Assemblies: Assembly automation and Hide/Suppress/Resolve components
Component state handling is its own objective. Know the difference between hiding, suppressing, and resolving, and how to change each state through the API on a component object.
- Iterate components of an assembly and act on them by state or name.
- Check the resulting state after the call rather than assuming it worked.
Drawings: Drawing Automation, Creation of drawings, Insert drawing views, Insert a BOM, Save drawings in different file formats
Five of the 15 objectives touch drawings, with some overlapping headings. Together they describe a complete workflow: create a drawing from a template, insert views of a model, add a bill of materials, and export to other formats.
- Know how drawing documents differ from part and assembly documents in the object model.
- Understand view creation parameters and BOM table insertion.
- Be ready to save in more than one output format.
Housekeeping: Add custom properties, Save and close documents
Custom properties are a favorite in real-world automation because they drive downstream data. Saving and closing correctly is equally practical: handle save options, errors, and clean document closure so sessions do not accumulate open files.
VBA Exam Skills vs. C# Add-ins and PDM API
One source of confusion about the credential's meaning is scope. The exam is anchored in VBA, which runs as a macro inside SOLIDWORKS. It does not test building compiled C# add-ins with their own UI, and it does not cover PDM API work. Those are adjacent skills that many API developers eventually acquire, but they are separate from what this exam examines.
| Skill area | On the exam? | Notes |
|---|---|---|
| VBA macros against the SOLIDWORKS API | Yes, the stated focus | Runs inside SOLIDWORKS; ideal for CAD users starting out |
| C# add-in development | Not the stated focus | Valuable career extension, but separate preparation |
| PDM API work | Not the stated focus | Different object model and tooling |
For a CAD user without a programming background, this is encouraging. A VBA-first path is a reasonable way in: you work in an editor built into SOLIDWORKS, you can record a macro to see the API in action, and then you replace brittle recorded steps with clean calls. The exam rewards that practical competence.
What the Credential Signals to Employers
Meaning is not only what the exam tests; it is also what a hiring manager infers. A CSWP-API on a resume suggests that the holder can automate repetitive modeling and drawing work, build tools for design teams, and troubleshoot code against the SOLIDWORKS object model. Typical settings include engineering departments with many variants of similar parts, manufacturers who generate drawings and BOMs at scale, and resellers or consultancies who build custom tooling for clients.
Be careful with claims about pay. There is no unsupported salary uplift to quote here, and any figure should come from your own market research. A more defensible way to assess value is through demonstrated automation: a macro that cuts hours from a weekly drawing release is concrete proof of return. For deeper analysis, see CSWP-API Salary Guide, Is the CSWP-API Certification Worth It?, and CSWP-API Jobs.
Key Takeaway
Treat the certificate as a credential that opens a conversation, and your portfolio of working macros as the evidence that closes it. Pair every skill you practice for the exam with a small, reusable automation you could show an employer.
Fee, Retakes, and Validity
- Fee: US$49 for one North American attempt, excluding software and training. See CSWP-API Certification Cost for the broader picture.
- Prerequisites: None required. SOLIDWORKS Design Essentials and API Fundamentals are recommended preparation, but training courses are not admission requirements. Details are in CSWP-API Requirements.
- Retakes: A new CSWP-API credit is needed, with at least a 14-day wait between attempts.
- Validity: The issuer's 2020 Certification Program Q&A states that customer and student certifications do not expire.
- Pass rates: No published population pass rate was verified. The 70% figure is the passing grade, not a pass rate. See CSWP-API Pass Rate for what can and cannot be said.
- Scheduling: CSWP-API Exam Dates covers how to approach timing.
The recommended SOLIDWORKS API Fundamentals course is a three-day offering whose public contents are a preparation curriculum (PMT2615-ENG, copyright 2025). The course length is separate from the two-hour exam and is not a mandatory training-hours requirement, and its headings are not an exam blueprint.
Preparing Based on What the Credential Means
If the credential means "can automate SOLIDWORKS with VBA," then preparation should look like building automation, not reading about it. Here is one short way to sequence the 15 objectives, with the reasoning attached to each phase.
Object model and troubleshooting first
- Learn to navigate API Help and read method signatures.
- Record simple macros, then rewrite them by hand to see what the recorder gets wrong.
- Reason: every later task depends on reaching the right object and diagnosing failures.
Sketches, dimensions, features, selection
- Build parts from code: sketch, dimension, extrude, cut.
- Practice selection and traversal on a feature tree you created.
- Reason: these are the highest-volume hands-on skills and share selection logic.
Assemblies and component states
- Iterate components; hide, suppress, and resolve them; confirm each state.
Drawings, BOMs, properties, saving
- Create a drawing, insert views and a BOM, add custom properties, export to multiple formats, then save and close cleanly.
- Finish with timed runs of mixed tasks to simulate the two-hour limit.
For a fuller plan, use the CSWP-API Study Guide, keep the CSWP-API Cheat Sheet nearby for quick review, and use the CSWP-API practice test site to test your conceptual recall. Because the multiple-choice portion is only 10 of 28 questions, practice questions complement, but never replace, hands-on macro work. If you want structured instruction, CSWP-API Training outlines options.
One more point on result checks: write each practice macro so it validates its own output, for example by counting features after creation, reading back a dimension value, or confirming a component's suppression state. This habit mirrors how you will catch mistakes during the real exam, and it turns each practice session into a reusable test fixture. You can compare your readiness against practice material at the main practice test site.
Frequently Asked Questions
It means Certified SOLIDWORKS Professional API, a SOLIDWORKS certification focused on automating the software through its API using VBA. More variations of this question are covered in What Does CSWP-API Mean? and What Is A CSWP-API?.
No. No prior certification is required. SOLIDWORKS Design Essentials and API Fundamentals are recommended preparation, but they are not admission requirements.
The linked guide describes it as a non-proctored online examination taken on your own working SOLIDWORKS installation and Internet connection. Follow the current VirtualTester Web Client instructions, which take precedence over legacy language in the guide.
According to the issuer's 2020 Certification Program Q&A, customer and student certifications do not expire.
Not directly. The exam focuses on VBA automation within SOLIDWORKS. C# add-in development and PDM API work are related but separate skill areas.
In short, the meaning of CSWP-API comes down to demonstrated, hands-on automation skill in SOLIDWORKS with VBA, measured across 28 questions in two hours. Learn the object model, practice building and verifying your own macros across the 15 objectives, and the credential becomes a reflection of work you can actually do.
