Drawing checks
Check dimensions, tolerances, callouts, and supporting documents against the requirements that apply to your drawing.

GD&T and dimensioning
- GD&T conformance to ASME Y14.5-2018 and ISO GPS, with clause citations.
- Invalid or undefined datum references and missing manufacturing dimensions.
- Over- and under-dimensioned features, with tolerance stack-ups across sheets and interfaces.
Callouts and annotations
- Surface finish, weld symbols, and thread callouts.
- Material and heat treatment callouts against specifications.
- Conflicts between notes and the drawing, plus units, scale, and title block consistency.
Codes and standards
- ASME BPVC, B31, and AWS checks, with citations.
- Your drawing standards, procedures, review checklists, and supplier specifications.
Cross-document checks
- Conflicting values and missing references across drawings, specifications, datasheets, and calculation reports.
- Calculation inputs checked against drawing dimensions.
Assembly and BOM checks
Match the parts and interfaces across your assembly documents.
View technical details
- BOM items matched to drawing balloons and assembly details.
- Missing parts, duplicate item numbers, quantity errors, and material conflicts.
- Inconsistent fastener callouts, interface dimensions, bolt patterns, and attachment details across drawings.
Revision review
Check revised drawings against reviewer markups and previous decisions.
View technical details
- Unresolved comments and undocumented changes.
- Previously corrected errors that reappear.
- Accepted deviations and review decisions retained across revisions.
P&ID review
Check piping and instrumentation diagrams and prepare revisions.
View technical details
- Line numbers, tags, and instrument bubbles checked for consistency.
- Line list and instrument index cross-checks, including off-page connector matching.
- Valve, specification break, and insulation callout checks.
- Revisions drafted from redlines and management-of-change requirements.
Construction drawing review
Cross-check drawings, specifications, models, and submittals.
View technical details
- Drawings checked against specification divisions and general notes.
- Sheet index, cross-reference, and BIM model consistency checks against issued drawings.
- Addendum and bulletin changes tracked across sheets.
- Submittals reviewed against contract documents.
