S01 · What is a contact point?
A contact point starts as a geometric relationship
Move the control. The same two parts go from clear, to close, to contact, to clash.
The figure needs JavaScript. States: clear, close, contact, clash.
Schematic · Illustrative · Not to scaleFig. A2. A geometric relationship is not automatically an engineering issue.
S02 · Inspection station
One contact point, four ways to look at it
In CATIA V5 a contact point can be examined from several views. This station uses a generic specimen, not a CATIA screen.
The figure needs JavaScript. Views: assembly, section, distance, contact.
Schematic · Illustrative · Not to scaleFig. A3. The same Node A in every view.
S03 · Clash analysis
From a full assembly to one contact point
A virtual full-vehicle assembly has many parts and many relationships. Clash analysis narrows the field to candidate interactions.
The figure needs JavaScript. Modes: assembly, show contacts, show clashes, isolate node.

S04 · From geometry to relevance
A geometric relationship is not automatically an issue
Whether a contact point is relevant is a judgement that follows investigation.
The figure needs JavaScript. Stages: geometric relationship, investigation, relevance screen.

Relevance screen
Outcome · not shown
Schematic · Illustrative · Not to scaleFig. A5. The screen exists. Its criteria and outcomes are not published.
S05 · Classification
Four ways to describe a relevant contact point
Relevant points are classified by type. Select a type to see the concept on the specimen.
The figure needs JavaScript. Types: clearance, collision, joining technique, surface properties.
Schematic · Illustrative · Not to scaleFig. A6. Concepts only. No real case is classified.
S06 · Criticality
Points are weighed, not just listed
Relevant contact points are weighted by criticality. The scale is qualitative and no point is placed on it here.
The figure needs JavaScript. Stages: points for prioritisation, toward the scale, scale with no positions assigned.
Schematic · Illustrative · Not to scaleFig. A7. Qualitative scale. No rankings, no values.
S07 · Problem reporting
Each relevant contact point gets a problem report
A report records the contact point, its classification, its criticality, the issue and the follow-up. This one is a synthetic structure.
Fields shown: contact point, classification, criticality, engineering issue, measure, follow-up.

S08 · Virtual follow-up
The task continues in the next virtual build phase
Validation of defined measures happens in the digital model only.
Current virtual build
Next virtual build phase
Defined measures can be checked again in the next virtual build phase.

AI-assisted analysis
One contribution inside a larger system
I contributed to an AI-assisted contact-point analysis by generating representative failure examples in CATIA V5. I did not develop or train the model.
