Vision Model and Image Analysis

TenderB's vision model can analyze images, technical drawings, diagrams, charts, and other visual content.

What the Vision Model Can Do

  • Extract Text: Read text from images, scanned documents, or screenshots

  • Analyze Technical Drawings: Interpret isometric drawings, floor plans, schematics

  • Identify Components: Recognize and catalog equipment or elements in images

  • Understand Spatial Relationships: Analyze how components are connected

  • Extract Data from Charts: Read values from graphs and visualizations

  • Describe Visual Content: Provide detailed descriptions of images

How to Use the Vision Model

Step 1: Attach an Image
Click the attachment (paperclip) icon and select an image file.

Supported formats:

  • PNG

  • JPG/JPEG

  • PDF (AI can analyze images within PDFs)

  • SVG (for technical drawings)

Step 2: Describe Your Request
Type a message explaining what you want the AI to do with the image.

Example Requests:

  • "Please analyze this isometric drawing and explain the flow of the system shown."

  • "Extract all the text from this scanned document."

  • "Identify all the components shown in this technical diagram and create a list."

  • "Please create a material purchasing list of all the components in this drawing."

Step 3: Send the Request
Click send. The AI processes the image and your request.

Step 4: AI Analysis
The AI analyzes the image and provides a response. For technical drawings, this might include:

  • System description

  • Component identification

  • Flow explanation

  • Technical details extraction

Example: Analyzing an Isometric Drawing

If you upload an isometric drawing of a fuel oil system, the AI might provide:

  • Complete system description

  • List of all components with functions

  • Flow path explanation

  • Key design features

  • Safety and redundancy elements

Creating Material Lists

Request: "Please create a material purchasing list of all the components in this drawing."

The AI generates a structured table with:

  • Item number

  • Description

  • Quantity

  • Specification notes

This list can be exported for procurement, cost estimation, or project planning.

Follow-Up Questions

Ask follow-up questions about the image:

  • "What is the purpose of the pressure relief valve?"

  • "Create a table showing all valves and their functions."

  • "Are there any potential design issues you can identify?"
