AI that understands engineering drawings.
Planstandard helps AEC teams review engineering drawings, ask practical QA questions, and improve documentation before issues affect schedules, budgets, and teams.
Drawing QA loop
Input
DWG/DXF + CTB/STB
Method
Spatial reasoning
Output
Revision layer
Engineering documentation, understood.
Upload a DWG or DXF drawing, with optional plot style tables (CTB/STB). Our AI analyzes geometry, annotations, and structure to find issues, explain findings, and answer questions.
01
Upload drawing
02
Add plot styles
03
Ask questions
04
Improve drawings
Verify the signals that are easy to miss.
The platform helps engineering teams catch the document-level quality issues that are hard to find manually and easy to lose in daily routines.
01
Drawing completeness
02
Missing annotations
03
Documentation consistency
04
Metadata quality
05
Cross-reference integrity
06
Standards compliance
Not architectural design review
Not structural analysis
Not professional consulting
Just documentation QA — done properly.
Built for drawings, not chat.
Reads CAD files, reasons over geometry and layers, and runs a documentation QA workflow — not an open-ended chat general agent.
Planstandard
Reads DWG/DXF and CTB/STB directly
Spatial reasoning over geometry, layers, and annotations
Retrieval from your standards and project docs
Private workspace built for engineering review
Predictable cost, built for efficient drawing QA
General agent
Needs screenshots, PDFs, or copied text
No structured understanding of CAD drawings
Generic knowledge, no project context
Consumer terms and free-form chat
Token cost grows with every prompt and retry
General questions → open-ended chat. Drawing questions → Planstandard.
Grounded engineering intelligence.
Answers are grounded in drawing context, engineering knowledge, and project documentation — not model memory alone.

AI agents capable of explaining every finding
Spatial AI, made practical.
Engineering drawings are complex symbolic documents. Planstandard turns that complexity into a practical QA workflow teams can use today.
01
Reduce human QA effort and time
02
Accelerate cross-functional coordination
03
Catch expensive issues before construction
04
Systemize engineering review workflows

Upload a drawing and the first thing most people ask is: "Summarize this drawing." The system answers politely — and the answer is almost always useless.
Simple questions are a trap. They cost you a token and give back information you already have: it's a floor plan, it has dimensions, there are some annotations. That is not QA. That is reading the title block out loud.
Planstandard is built for reasoning: cross-referencing sheets against schedules, checking standards, finding contradictions, tracing revisions. But that only happens if you force it to work.
Compare these two prompts:
"What is this drawing?" → "It is a second floor plan."
"Do all revision clouds on sheet A-102 have matching entries in the revision schedule, and do the cloud numbers match the sequence in the title block?" → A list of missing entries, mismatched numbers, and the exact locations to check.
The second question is harder to type, but it saves you the hour you would have spent scrolling and comparing manually.
So don't treat the system like a search box. Treat it like a QA engineer you just handed the drawing set. Ask it to compare, verify, trace, and challenge assumptions. The harder the question, the more useful the answer.
Upload your next drawing and ask something you'd normally need an hour to check by hand.
Need a system built around your standards?
Planstandard can be adapted to your drawing sets, review criteria, and internal QA process. If the basic workflow fits, we can help build custom models, retrieval workflows, and deployment options around your organization’s standards.
01
Adapt review prompts and checks to your drawing standards
02
Build retrieval workflows from your specifications and project documentation
03
Configure models for recurring drawing types and QA patterns
04
Support private deployment paths when your data or infrastructure requires it
Use the live workspace to validate the workflow, then extend it with custom models and deployment options built around your standards.
Start with the workspaceStart with a real drawing and practical questions.
Upload an engineering drawing in the workspace, ask targeted questions, and compare the assistant's answers with your own expert judgement.
