How the 17 Areas Are Defined (and What They Are Not)
SOLIDWORKS describes the Certified SOLIDWORKS Professional Model Based Design (CSWP-MBD) exam as a set of hands-on MBD challenges. On its certification page, the issuer lists the functionality areas in which those challenges appear. Counted carefully, the list yields 17 distinct areas. The source list actually shows 18 bullets because Annotation Views appears twice; it is one area, and it is counted once here.
That distinction matters, because you will see third-party sites present "domain weightings" such as neat percentage splits across topics. The issuer publishes no such blueprint. The 17 areas are a list of where hands-on challenges occur, not a weighted outline, and the number of headings tells you nothing about how many tasks any single area contributes. Treat every area as fair game, and be skeptical of any resource that claims to know the exact mix.
For a broader preparation plan that wraps around these areas, see the CSWP-MBD Study Guide 2026: How to Pass on Your First Attempt. If you want a sense of how demanding the hands-on format feels, read How Hard Is the CSWP-MBD Exam? Complete Difficulty Guide 2026.
Model Based Definition vs. Model Based Design
The credential is titled Model Based Design, while the issuer's own descriptions refer to Model Based Definition tools and name the credential SOLIDWORKS MBD Professional. These point to the same exam. The wording difference is a naming quirk, not evidence of a second certification. In practice, the work is Model Based Definition: attaching product and manufacturing information (PMI) directly to the 3D model so that the model, rather than a 2D drawing, carries the authoritative definition of the part.
Keep that framing in mind as you work through the areas below. Almost every one of them is a way of putting dimensions, tolerances, notes or views onto the 3D model, or of packaging that information for others. If you are new to the terminology, the explainers What Is CSWP-MBD? and What Does CSWP-MBD Stand For? cover the basics.
The Dimensioning Cluster
Four of the 17 areas deal with the kinds of dimensions you apply to a model. They are easy to confuse, so it pays to understand what distinguishes each.
Domain 1: Reference Dimensions
Reference dimensions report a value without driving or constraining geometry. In an MBD context, you need to know when a reference dimension is the right choice and how it appears on the model.
- Recognize that a reference dimension is informational, not controlling
- Know how it differs visually and functionally from a driving dimension
- Be ready to add or identify one within a timed challenge
Domain 3: Size Dimensions
Size dimensions define the extent of features such as diameters, widths and depths. Under DimXpert, they describe how big a feature is rather than where it sits.
- Distinguish size from location when choosing a dimension type
- Apply size dimensions to features and confirm they attach correctly
- Understand how size dimensions interact with tolerance settings
Domain 13: Location Dimensions
Location dimensions control where a feature sits relative to a datum or another feature. The size-versus-location split is a core idea in dimensioning a part for manufacture.
- Select appropriate references for locating features
- Keep size and location dimensions logically separate
- Check that your scheme fully defines the feature without over-defining it
Domain 8: Auto Dimension
Auto Dimension applies a dimensioning scheme to a part automatically. The skill is not just running the tool but evaluating what it produced and adjusting it.
- Know the options that influence the generated scheme
- Review the output for completeness and correctness
- Be ready to edit, delete or supplement automatically created dimensions
A useful drill: take one simple prismatic part and dimension it three ways: manually with size and location dimensions, with Auto Dimension, and with a few reference dimensions added for verification. Comparing the three results builds the judgment these four areas test.
Geometry References: MidPlane and Intersection Geometry
Two areas concern how you reference geometry that is not simply a visible edge or face.
Domain 2: MidPlane
MidPlane references let you dimension or tolerance relative to the center plane between two faces, as with a slot or a pair of parallel surfaces. It is a common way to express symmetry-based intent.
- Know how to establish a midplane between opposing faces
- Apply dimensions or tolerances to a midplane rather than an individual face
- Recognize cases where midplane referencing is clearer than face-to-face dimensioning
Domain 5: Intersection Geometry
Intersection geometry deals with references created where features meet, letting you dimension to a point or edge that does not exist as a single selectable entity.
- Understand when intersection references are needed
- Know how to create and select them reliably
- Verify that the resulting dimension attaches to the intended geometry
These two areas reward hands-on repetition more than reading. Build a small part with a symmetric slot and an angled intersection, then practice dimensioning both until selecting the right reference feels routine.
DimXpert, Auto Dimension and Tolerance Controls
DimXpert is the toolset at the center of MBD annotation in SOLIDWORKS, and several of the 17 areas are really facets of it.
Domain 7: DimXpert
DimXpert is the umbrella for applying dimensions and tolerances to a part model. Familiarity with its interface and manager is the foundation for many other areas on the list.
- Navigate the DimXpert manager and its tool set confidently
- Understand how DimXpert recognizes features and attaches annotations
- Work quickly, since the exam is timed
Domain 9: Tolerance Style
Tolerance style governs how tolerances are expressed on dimensions, including the format used and the default values applied across the part.
- Know where tolerance style is set and how it propagates
- Be able to change a style and predict the effect on existing annotations
- Understand the difference between a style default and an individual override
Domain 11: Tolerance Status
Tolerance status reports whether the features of your part are fully constrained by the tolerance scheme you have applied. It is a checking tool, and learning to read it is a skill in itself.
- Interpret what the status indicators mean
- Use the status to find under-defined or conflicting features
- Resolve the issues it flags and re-check

Views, Notes and Flag Notes
Another group of areas covers how information is organized and communicated on the model rather than how geometry is dimensioned.
Domain 4: Annotation Views
Annotation views are planes on which annotations are placed and organized, so that PMI displays in a controlled, readable way instead of piling up in one place.
- Create and manage annotation views
- Assign annotations to the correct view
- Understand how orientation and visibility affect what the reader sees
Domain 14: 3D Views
3D views capture a specific orientation, zoom and display state of the model. This is the part that is easy to confuse with annotation views, yet the two serve different purposes.
- Capture and name 3D views for downstream use
- Know how they relate to what ends up in a published file
- Keep the distinction clear: an annotation view organizes where annotations live, while a 3D view records how the model is displayed
Domain 10: Notes
Notes carry text-based requirements that dimensions cannot express, such as material, finish or general conditions.
- Add notes to the model and attach them to the proper annotation view
- Format and edit notes accurately
- Know how notes interact with other annotations
Domain 12: Flag Note Bank
The flag note bank stores reusable notes so common callouts can be inserted consistently rather than retyped each time.
- Understand how to access and use the note bank
- Know how a flag note differs from a standard free-text note
- Apply stored notes quickly and correctly under time pressure
Annotation views and 3D views are the pair most worth drilling together. The CSWP-MBD Cheat Sheet 2026: One-Page Review of Must-Know Facts is a good quick reference for keeping the distinction fresh before an attempt.
Copy Scheme and Pattern Feature
Two areas test efficiency: getting annotations onto repeated or similar geometry without redoing the work.
Domain 15: Copy Scheme
Copy Scheme replicates a dimensioning and tolerancing scheme from one feature or part to others, saving time and ensuring consistency.
- Identify what can be copied and from where to where
- Verify that the copied scheme attached as intended
- Recognize when copying is faster than starting fresh
Domain 16: Pattern Feature
Patterned features, such as a bolt-hole circle or a linear array, have their own handling for PMI. Dimensioning the pattern as a pattern is cleaner than dimensioning each instance separately.
- Apply pattern-aware dimensions and tolerances
- Confirm that all instances are covered
- Understand how pattern dimensioning differs from dimensioning individual features
A practical exercise: model a plate with a patterned hole set and a second, similar feature elsewhere. Dimension the pattern once, then use Copy Scheme on the similar feature and check the result with Tolerance Status.
Defining PMI and the 3D PDF Workflow
The last two areas look at the bigger picture: defining the full set of product and manufacturing information and then publishing it.
Domain 17: Defining PMI
Defining PMI is the umbrella skill of attaching everything a manufacturer needs (dimensions, tolerances, notes and more) to the model in an organized, complete way.
- Combine the individual tools into a coherent annotation of a part
- Check completeness, not just presence of individual annotations
- Think in terms of what a downstream user would need
Domain 6: 3D PDF Tools
3D PDF tools package a model with its PMI into a shareable document that others can open without the original CAD software.
- Know how to publish a model with its annotations to a 3D PDF
- Understand how views and annotations carry into the output
- Be prepared to apply the publishing tools to a part you have just annotated
A clean end-to-end workflow ties nearly every area together: model the part, define PMI with DimXpert, organize it with annotation views and 3D views, add notes and flag notes, check Tolerance Status, then export to 3D PDF. Practicing that full chain on two or three different parts is probably the most efficient way to touch all 17 areas.

Exam Mechanics You Should Know
Knowing the domains is half the preparation; knowing the logistics removes surprises. The facts below come from the issuer's published information.
| Item | What the issuer states |
|---|---|
| Format | Hands-on MBD challenges |
| Duration | 90 minutes; the exam cannot be paused |
| Passing grade | 75% minimum |
| Question total | Not published on the official exam page |
| Fee | US$49 for one North American attempt, excluding software and training |
| Delivery | Through Tangix/VirtualTester; current instructions use the VirtualTester Web Client |
| Software | SOLIDWORKS 2016 or later, with the necessary MBD functionality, plus Internet access |
| Retakes | At least 14 days between attempts, and a new CSWP-MBD credit is required |
| Prior certification | None required under the general Professional-exam FAQ |
| Validity | Per the issuer's 2020 Q&A, customer and student certifications do not expire |
Two cautions. First, the 2016 software figure is a compatibility minimum, not a content-outline year. Second, the 75% passing grade is a score threshold, not a pass rate; published population pass rates have not been verified. The pages on CSWP-MBD Passing Score 2026, CSWP-MBD Pass Rate 2026 and CSWP-MBD Certification Cost 2026 go deeper on each. Eligibility questions are covered in CSWP-MBD Requirements 2026, and scheduling in CSWP-MBD Exam Dates 2026.
A Domain-Ordered Study Sequence
Because the areas build on one another, order matters more than total hours. The sequence below groups them by dependency. It is a suggested structure, not an official plan, and the one-day SOLIDWORKS MBD course is not a required number of training hours.
Foundations: DimXpert and dimension types
- DimXpert, Size Dimensions, Location Dimensions, Reference Dimensions
- Why first: every later area depends on comfort with the annotation tools
References and automation
- MidPlane, Intersection Geometry, Auto Dimension
- Why now: these extend your dimensioning options once the basics are solid
Tolerances and checking
- Tolerance Style, Tolerance Status, Copy Scheme, Pattern Feature
- Why now: tolerance work needs dimensions in place, and Status verifies your scheme
Organization, publishing and timed runs
- Annotation Views, 3D Views, Notes, Flag Note Bank, Defining PMI, 3D PDF Tools
- Finish with full timed, 90-minute run-throughs of annotate-then-publish
Key Takeaway
Do not study the 17 areas as 17 isolated topics. Annotate one real part end to end, then repeat on a second part with different geometry. You will cover most areas several times and build the speed a 90-minute, unpausable exam demands. When you want realistic timed repetition, try the CSWP-MBD practice tests.
