Choosing a drawing tool for looks while underestimating how much retagging and identifier consistency drive rework
SmartDraw P&ID Software and Hexagon Smart P&ID both emphasize tagging-driven or intelligent tagging behaviors, so buyers should validate identifier consistency during actual edit scenarios before standardizing. If the workflow requires controlled retagging, CADMATIC P&ID should be prioritized because its tagging is designed for retagging during edits.
Treating off-page connectors and line numbering as optional when projects span multiple sheets
CADMATIC P&ID includes off-page connectors and line numbering to reduce cross-sheet cleanup after edits, so multi-sheet projects should test those behaviors with real layouts. If line numbering and annotation conventions are not configured, PROCAD P&ID requires disciplined configuration to keep those conventions consistent.
Assuming revision control is automatic without governance of symbols, tagging standards, and legend behavior
AVEVA P&ID requires setup discipline to keep tagging, numbering, and legends consistent, so buyers should plan for configuration work. Siemens COMOS also needs governance of engineering data rules and symbol libraries, so symbol standardization should be part of implementation planning.
Expecting robust external workflow orchestration and API-first automation from suites that center on drafting and publishing
Multiple cards note that automation and API surface are limited versus integration-first workflow tools, so buyers should map automation needs to the tool’s actual strengths. If orchestration is the priority, the selection should be based on how the tool integrates into document publishing cycles rather than assuming in-app automation can coordinate external systems.
Over-optimizing CAD file conversion while ignoring semantic consistency across P&ID editing
EdrawMax provides DWG import plus DXF export for handoff, but its CAD interoperability focuses on conversion rather than full drawing semantics for tag governance. AVEVA P&ID also supports DWG import and DXF export but ties interoperability to design change tracking workflows, which better supports traceability across revisions.
