Turn product geometry into a clear engineering reference. Bring views, dimensions and requirements together for the people who manufacture, inspect and review your design.
Explore CAD drawingsA CAD drawing is a digital technical document that communicates how a part or assembly is defined. It combines selected views of geometry with dimensions, notes and other requirements so another person can understand the design without having to interpret the model alone.
The 3D model describes shape; a drawing selects the views and instructions needed for a particular handoff. A detail sheet may define a single manufactured part, while an assembly sheet explains how components fit together. The useful question is what the receiving team must be able to make, check or review.
A drawing makes a design decision usable beyond the CAD workstation. It gives manufacturing, suppliers and inspection a common reference for the requirements that are difficult to infer from shape alone.
A hole may look correctly placed in a model, but its location, size and permitted variation must be understood by the people producing and checking it. Select views that expose the requirement rather than making a reader search for it.
A reviewer needs to connect a requirement to a feature and an identifiable revision. Drawing views, notes and references make it possible to raise a specific question and record what needs attention before release.
A changed feature can affect more than the drawing view. Identify the impacted dimensions, related components and downstream documents, then use the appropriate review and release process to communicate the approved change.
PTC’s “Change Management” film looks at how Windchill coordinates proposed changes and stakeholder review. It provides the process context around a revised drawing, rather than a lesson in creating drawing views.
Explore Engineering Change ManagementDrawing software supports the work of creating and maintaining a readable definition. Its value depends on how well templates, references and review practices are set up—not simply on replacing a pencil with a screen.
Create geometry with defined sizes and relationships. Use dimensions deliberately and review the resulting definition; numerical precision alone does not establish an appropriate tolerance.
Use sections and enlarged details to expose internal features or small interfaces. Select enough views to resolve ambiguity while keeping the sheet readable.
Reusable sheet formats, symbols and approved library content help teams apply their documentation conventions. Agree which templates and standards apply to the project.
In an associative workflow, drawing views follow their referenced model. Review annotations, dimensions and layout after a change rather than assuming an updated view is a released deliverable.
Share outputs suited to the recipient’s tools and task. Check scale, units, fonts, references and required annotations when publishing or exchanging a drawing.
Reuse suitable formats and established detailing practices across similar work. Maintain those resources so a reused starting point does not carry forward obsolete requirements.
The same product geometry can support several kinds of work. Match the output to the reader’s responsibility, so a manufacturing requirement and an explanatory illustration are not confused.
Prepare the views and requirements that communicate design intent, then resolve the questions raised during manufacturing and inspection review.
Typical outputA component detail or assembly definition
Reuse CAD geometry to make an assembly sequence, service illustration or instruction easier to follow. Technical illustrations serve a different purpose from a drawing that controls manufacturing requirements.
Typical outputAn exploded figure or illustrated instruction
Use readable drawings and visual outputs to discuss interfaces, scope and proposed revisions with the responsible specialists. Visibility supports a decision; it does not replace engineering approval.
Typical outputA documented review or change question
Choose the tool around the deliverable. Engineering drawings and technical illustrations can originate from related CAD data, but they answer different questions and should keep their own review responsibilities.
Creo supports model-associated drawing views and detailing for parts and assemblies. Use the model as the reference for the drawing, then prepare the dimensions, annotations and sheet presentation needed by the receiving team.
Confirm drawing standards, data exchange needs and the capabilities included in your proposed package.
Explore CreoPTC Illustrate reuses CAD data for technical illustrations, including exploded figures, callouts and sequences. It helps communicate assembly and service work when the audience needs to understand an action or relationship.
An illustration complements the controlled engineering definition; it should not be treated as a substitute for its manufacturing requirements.

Drawing practices depend on the product, the receiving team and the organization’s requirements. These examples show where a readable engineering definition helps frame the work.
Define machined interfaces, mounting patterns and assembly relationships so manufacturing and inspection can refer to the same product requirements.
Which features need a section or detail view to make the requirement clear?
Document enclosure interfaces, connector openings and mounting requirements around the electronic product. Keep mechanical detail tied to the agreed assembly reference.
Which mechanical interfaces must remain clear to the enclosure and assembly teams?
Prepare drawings within the project’s established configuration and review practices. Identify the applicable product reference and the requirements that need specialist review.
Which revision and configuration should the receiving team use?
Practical questions about drawings, models and the information you share.
A model represents geometry and its relationships. A drawing organizes selected views with dimensions, notes and references for a specific communication task. Some workflows also place product manufacturing information directly on the 3D model; agree which deliverable controls the work.
Use the views needed to describe the part clearly: orthographic views for shape, sections for internal features, detail views for small areas and an isometric view for orientation when useful. More views are not automatically better; avoid duplicate or conflicting definition.
In an associative drawing workflow, views reference the model and can reflect its changes. An engineer still needs to review dimensions, annotations, placement and affected requirements before the drawing moves through the release process. Behavior depends on the application and drawing setup.
No. A technical illustration explains a product, relationship or action, such as an assembly sequence. An engineering drawing communicates the requirements used to define, manufacture or inspect the product. Use each output for its intended audience.
Confirm the part and revision, units, scale, view completeness and required annotations. Check the exported result in the format the recipient will use, and identify whether it is a working copy, a review copy or an approved deliverable.
Yes. The core task is communicating geometry and requirements, while documentation practices and approval responsibilities vary by organization and industry. Select templates, exchange formats and review processes that match the actual project.
