Parametric by design
Dimensions, features and relationships capture how a part is meant to change.
Develop the geometry, investigate its behavior and define how it will be made. Keep those decisions connected to the model as the product evolves—from the first design question to the next engineering handoff.
Creo is PTC’s parametric 3D CAD software for product design, engineering and manufacturing. Create parts and assemblies around design relationships, evaluate alternatives and develop the definition needed to make the product.
From an enclosure interface to a complex machine, the model becomes a common reference for geometry, analysis and production information. Choose the capabilities that match your team’s work, with room to add specialist tools as that work grows.

Use Creo to develop product geometry, investigate performance and prepare manufacturing definition. Parametric relationships and integrated tools help teams reuse established work, compare changes earlier and carry clearer information into the next handoff.
Build parts and assemblies around dimensions, features and interfaces that express the product’s intent. Reuse established geometry and explore a change without starting every decision from a blank model.
A model with understandable design relationshipsBring simulation and analysis into the CAD workflow. Investigate the design under stated materials, loads and constraints, then refine the geometry using the level of analysis the question requires.
A design considered alongside its performance assumptionsDevelop annotations, machining information, tooling or additive preparation around the applicable model. Carry a clear definition into the manufacturing discussion and keep the required review and process context with it.
Geometry and production information that belong togetherReuse design relationships and product-family geometry instead of rebuilding every variation.
Bring performance questions into the design workflow before committing to the next physical prototype.
Develop annotations and production information around the same design definition.
Each contributor brings a different decision to the same product definition. Start with the work your role needs to accomplish, then connect it to the people and information around it.

What must stay consistent when the geometry changes?
Develop parts, surfaces, sheet metal and assemblies with controlled design relationships. Work through interfaces and variations while keeping the intent understandable to the next person who revisits the model.
How will this form become a working part?
Use the model to develop machining, tooling or additive preparation. Consider tool access, process choice and production information as part of the engineering work, with the relevant manufacturing capabilities selected for your process.
Which assumptions shape the predicted response?
Select the analysis method for the decision—from interactive design feedback to deeper structural, thermal, modal or other studies. Keep materials, boundary conditions and the model revision in view when comparing alternatives.
How will the team work from a consistent environment?
Plan packages, entitlements, configuration and updates around real user responsibilities. Establish templates and data practices, and compare Creo with Creo+ administration and collaboration needs before choosing the delivery model.
Can the next team understand the decision behind the model?
Look across design, analysis and manufacturing handoffs to identify the information each team needs. Use a model-based approach to keep the engineering discussion focused on the product and the decisions that move it forward.

Drawing and 3D annotation workflows can coexist. Specialist GD&T and tolerance tools require the relevant extensions.
Use embedded guidance to learn a workflow or find a relevant Creo tool. Model-aware assistance adds a different level of context where its release, entitlement and access requirements are met.
Ask about a feature workflow, then apply the guidance in the context of your engineering task.
Creo Advise provides general guidance. Advanced model-aware and modifying capabilities have separate entitlement and preview availability.
Bring questions into the design environment, with assistance grounded in Creo information. Choose between general guidance and the model-aware capabilities available to your organization, then review the information in relation to the task you are doing.
Get guidance supported by Creo Help and Technical Support content. Advise answers general product and workflow questions without analyzing the active model, helping users discover tools and recommended practices.
Model-aware assistance can work with the active model, selections and design environment. Assist is a Beta capability with paid Advanced AI entitlement and participation requirements; confirm access for the release your team uses.
Automation is the modifying layer of Assist. Where preview access is authorized and modification is enabled, users review and accept or reject proposed changes. It is not a separate mode that every user can turn on.
Advise is generally available from Creo 13.4 and does not consume AI credits. Advanced AI requires separate entitlement and administration. Assist and automation availability remains release-specific and restricted; PTC-managed services support both Creo and Creo+.
