Start here: Operator
Look up an accepted result and recognise its current evaluation status.
OperatorYour roleStart here: Supervisor
Evaluate exact inputs, accept fixed results and control evaluation packs and handovers.
SupervisorYour roleStart here: Author
Capture a complete engineering model with independently calculated cases before submission.
AuthorYour roleStart here: Reviewer
Independently review model changes, approve candidates and select the release used for new evaluations.
ReviewerYour roleStart here: Owner
Arrange site access, readiness, private archives and recovery without approving engineering content.
OwnerYour roleStart here: Viewer
Inspect accepted engineering records, provenance and current eligibility without changing them.
ViewerReferenceRoles, actions and additional checks
Identify exact read, authoring, evaluation, handover and recovery authority, including the evaluation-only release boundary.
Owner · Author · Reviewer · Supervisor · Operator · ViewerReferenceEvaluation and observed handover inputs
Check the exposed field formats, units, bounds and required evidence, then resolve the actual refusal before recording work.
Supervisor · Author · ReviewerAuthoringBuild an engineering family
Define a bounded model, declared dependencies and meaningful scope before saving a draft.
AuthorAuthoringDeclare inputs and exact calculations
Set meaningful types, bounds, precision and expressions before checking boundary cases.
Author · ReviewerAuthoringDefine component lines and blocking conditions
Specify exact parts, counts, dimensions and explicit reasons for unsupported configurations.
Author · ReviewerAuthoring and approvalWrite independent cases and inspect proof
Calculate expected values and the complete component list from the engineering source before comparing the model.
Author · ReviewerAuthoring and approvalReview an exact candidate and its engineering impact
Compare full model differences, independent expectations and affected results before approval.
Reviewer · AuthorAuthoring and approvalActivate an approved release or review a reversion
Prepare a current impact comparison and deliberately select the model for new evaluations.
ReviewerAuthoringImport models and inspect dependency changes
Review a prepared model or typed reference-table import before saving it into the family draft.
Author · ReviewerEveryday workConfigure a unit and accept its exact result
Evaluate declared inputs against the active family, inspect the full preview and accept deliberately.
SupervisorEveryday workAmend a configuration or prepare a remake
Reuse source inputs with an explicit release decision and fresh evaluation while preserving accepted history.
SupervisorEveryday workIssue an evaluation pack and record actual handover
Issue a fixed evaluation pack and work through an illustrative transfer, independent review and withdrawal follow-up.
Supervisor · ReviewerExceptionsWithdraw unsafe evidence and follow up affected recipients
Hold results or dependencies with a recorded reason and retain the original engineering history.
Reviewer · SupervisorRecords and evidenceRead accepted results and recheck retained calculation
Distinguish immutable output, current eligibility and a recheck of the original engineering basis.
Operator · Supervisor · Reviewer · ViewerSite administrationPreserve archives, reconcile a restore and close deliberately
Verify the private archive and Owner recovery evidence before administrative decisions.
Owner · SupervisorSite administrationSet up the evaluation site and prepare support evidence
Read site readiness, activity and health without confusing administrative evidence with engineering approval.
