How to Use OpenDocs: Core Workflows
Step 1: Launch & Initialize
Open the OpenDocs application through your Visual Paradigm online workspace. You’ll be greeted by a welcome screen where you can manage recent projects [[6]].
Step 2: Create and Name Your First Page
Click the “New Page” button in the sidebar to create a Markdown document, then give it a descriptive name to stay organized.
Step 3: Write and Format Content
Use the Markdown editor to start writing. Apply standard Markdown syntax to add structure, emphasis, code blocks, and tables to your notes.
Step 4: Generate Visual Diagrams
-
Click “Insert” → “Diagrams” tab → select your desired diagram type
-
For AI generation: Click “Create with AI”, enter a natural language description, and click “Generate” [[19]]
-
For manual creation: Use the drag-and-drop editor with the comprehensive shape palette
Step 5: Organize with Folders
Create new folders via the sidebar and drag-and-drop pages or diagrams into them to build a structured, navigable knowledge base.
Step 6: Share Your Work
Generate a secure sharing link to distribute your entire knowledge base to collaborators or stakeholders with read-only access.
AI-Powered Workflow Example: Creating a UML Profile Diagram
-
Open your OpenDocs document in the web browser
-
Click Insert → Diagrams tab → Profile Diagram
-
Click Create with AI (top-right corner)
-
Enter a domain-specific prompt:
“Create a UML profile for automotive software with stereotypes for ECU, Sensor, and Actuator components, including tagged values for priority and compliance standards.”
-
Click Generate – the AI processes semantics and returns a structured diagram
-
Refine layout, add elements, or adjust stereotypes as needed
-
Click Save → diagram embeds automatically into your document [[19]]
💡 Pro Tip: Use specific, context-rich language for better AI results. The more domain context you provide, the more accurate and actionable the output.
