Figure 1 – Connecting Rod Features

Understanding Parametric Concepts

The parametric nature and feature-to-feature relationships in Creo Parametric enable you to easily capturedesign intent and make design changes.

Parametric:n Model geometry is controlled by parameters and dimensions.n When you modify dimension values, relevant geometry is automatically updated.Parent/child relationships:n Features referenced during creation become parents.n If parent features change, child features predictably change accordingly.

Figure 1 – Parametric Feature Relationships

Understanding Associative Concepts

Creo Parametric is a bi-directionally associative product development tool.

Figure 1 – Associativity

Understanding Model-Centric Concepts

In Creo Parametric, the model is the center of all downstream deliverables.

Module 27 : Resolving Failures and Seeking Help


Objectives

After completing this module, you will be able to:n Understand and identify failures.n Analyze geometry, open-section, and missing part references failures.n Analyze missing component failures, missing component reference failures, and invalid

assembly constraint failures.n Understand resolve mode tools.n Recover models.n Access and use Creo Parametric's help system.

Understanding and Identifying Failures

When a model fails regeneration, the system indicates the failing features or components.

n Failures occur due to:– Invalid/Impossible geometry– Missing/Broken references– Missing models

n Failure Indications:– Regeneration Manager:– Regeneration Caption– Red Highlighting• Model tree• Model geometry

Figure 1 – Regeneration Caption

Figure 2 – Feature Highlighting Figure 3 – Regeneration Manager

Analyzing Geometry Failures

Geometry failures are caused either by geometry that has been made invalid, or geometry that is impossible tocreate.

Figure 1 – Round Radius Too Large

n Invalid geometry examples:– Round radii too small or too large– Blend start points mismatch– Sweep Radii Rule– Extrude Through Until

Figure 2 – Sweep Radius Section RadiusComparison Figure 3 – Blend Start Points Mismatch

Analyzing Open Section Failures

Open section failures occur when the open section extends beyond the solid geometry that bounds it.

n Open section features must be bounded byother solids.

n Failure message indicates when a partcannot be intersected with a feature.

Figure 1 – Open Section Versus Closed Section

Figure 2 – Open Section Sketch Feature Figure 3 – Open Section Sketch Failure

Analyzing Missing Part Reference Failures

Missing part reference failures occur when a parent feature is changed, and the child feature can no longer findthe parent's reference.

n Missing part reference failure examplesinclude:– Missing axes– Missing references for rounds/chamfers– Editing a sketch• Replace sketched entities• Replace Sketcher dimensions Figure 1 – Sketch Feature Referencing Hole Axis

Figure 2 – Round Edges Figure 3 – Editing a Sketch

Analyzing Missing Component Failures

Missing component failures occur when Creo Parametric cannot locate all of the necessary componentsto properly open an assembly.

n Reasons include:– Component renamed on operating system.– Component renamed in Creo Parametric

without assembly in session.– Component located in a different folder on

operating system.

Figure 1 – Folder View of Components

Figure 2 – Assembly and Model Tree

Analyzing Missing Component ReferenceFailuresMissing Component Reference failures occur when you modify a component feature that removes the referenceused for its placement or its children's placement in an assembly.

n Failure displays as:– Failed to regenerate component

placement.– Feature references are missing.

Figure 1 – Parent/Child Relationship Graph

Figure 2 – Model Tree and Assembly

Analyzing Invalid Assembly Constraint Failures

Invalid assembly constraint failures occur when constraints from one set conflict with constraints from anotherset for a given component.

n Reasons include:– Parent components modified or deleted.– Features in parent components modified or deleted.

n Resolve the failure:– Change constraints.– Modify features to satisfy constraints.– Suppress or freeze component.

Figure 1 – Invalid Assembly Constraints

Figure 2 – Coincident Constraints Disabled Figure 3 – Features Modified to Satisfy Constraints

Understanding Resolve Mode Tools

If desired, you can activate Resolve mode to manage failures.

Activate Resolve mode using:n Regeneration Manager preferences

– Failure Handling• No Resolve mode (default)• Resolve mode

n Config.pro option– regen_failure_handling• no_resolve_mode (default)• resolve_mode
