How it works.
Your drawings, specifications, and standards. Findings and drafts ready for engineering review.
Upload your drawings.
PDFs, scanned prints, or complete release packages.
HERA checks them.
Against applicable standards, specifications, and your team’s checklists.
Review the findings.
See what needs attention, where it appears, and which requirement applies.
Keep each revision in context.
Compare revised drawings with markups and earlier decisions.
- Unresolved comments
- Undocumented changes
- Accepted deviations

Drawing checks
Check dimensions, tolerances, callouts, and supporting documents against the requirements that apply to your drawing.
View technical details
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.
Document drafting
Prepare manufacturing documents, inspection records, and drawings for engineering review.
View technical details
Manufacturing documents
- Work instructions from drawings, specifications, and existing shop procedures.
- Assembly procedures with materials, dimensions, and process parameters.
- Inspection checklists with acceptance criteria.
Inspection preparation
- Automatically ballooned drawings and dimensional requirements exported to inspection characteristic lists.
- FAIR, AS9102, and PPAP form population.
3D to 2D drafting
- View generation from STEP and native CAD, with automatic dimensioning and item numbering.
- BOM extraction, title block population, and revision block updates.
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.
Process capability library
Check incoming drawings against your shop and supplier capabilities.
View technical details
- Material compatibility and part size and weight limits for each process.
- Batch size ranges and quality capabilities for each shop or supplier.
- Producibility flags for requirements outside those capabilities.
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.
