Model.dwg Creation & Named Views

Understanding MODEL.dwg: The Hub of Your Project

MODEL.dwg is where all your design elements come together. It references all Data Shortcuts (surfaces, alignments, corridors, pipe networks), adds annotations and labels, and serves as the single source for all sheet files. This is the culmination of the entire workflow.

Purpose of MODEL.dwg:

• Aggregation: Brings together all design elements via Data Shortcuts
• Annotation: Add labels, dimensions, call outs, notes
• Named Views: Define views for each sheet area
• Xref Source: Referenced by all sheet files
• Single Source: Update MODEL, all sheets update

Creating MODEL.dwg Step-by-Step

Step 1: Create the Drawing

1. Create new drawing from template
2. Save as: MODEL.dwg in 04_Design/Model/
3. This is THE model file for your entire project

Step 2: Attach BASE-XREF

1. Type XREF
2. Attach BASE-XREF.dwg with relative path
3. This provides property lines, ROW, reference features

Step 3: Reference All Data Shortcuts

Bring in all design elements:

• Surfaces:
  • Toolspace > Prospector > Data Shortcuts > Surfaces
  • Right-click EG > Create Reference
  • Right-click FG > Create Reference
  • Right-click Corridor surfaces > Create Reference
• Alignments:
  • Data Shortcuts > Alignments > Centerline Alignments
  • Create references for all project alignments
• Pipe Networks:
  • Data Shortcuts > Pipe Networks
  • Create references for storm, sanitary, water networks

Step 4: Add Annotations

Now add labels, dimensions, callouts:

• Surface Labels: Spot elevations, contour labels
• Alignment Labels: Station/offset callouts
• Profile Labels: Elevations along alignments
• General Notes: Text objects with project-specific information
• Dimensions: Key distances, clearances
• Symbols: North arrow, benchmark callouts

Named Views: Setting Up Sheet Boundaries

Named Views define specific areas of MODEL.dwg that will become sheets. Each view corresponds to one sheet.

Creating Named Views:

1. Type VIEW or go to View tab > Views panel > View Manager
2. Click New
3. Configure view:
   • View Name: Match sheet number (e.g., "C-101", "C-102")
   • View Category: Organize views (e.g., "Plan Sheets", "Profile Sheets")
   • Boundary: Define with window or current display
   • Layer Snapshot: Save layer states with view
4. Click OK—view saved

Defining View Boundaries:

Two methods:

• Current Display: Zoom to desired sheet area, create view from current screen
• Define Window: Draw rectangle defining sheet limits, select as boundary

Best Practices for Named Views:

• Name views to match sheet numbers for easy identification
• Use consistent view scales (e.g., all plan sheets at 1"=50')
• Include layer states if different sheets show different layers
• Organize views into categories for large projects
• Test views before creating sheets—restore each view to verify coverage

MODEL.dwg Workflow Integration

The Complete Flow:

1. Design Phase: Create surfaces, alignments, corridors, networks in separate design drawings
2. Data Shortcuts: Create shortcuts for all design objects
3. MODEL.dwg: Reference all shortcuts, add annotations, create named views
4. Sheet Files: Xref MODEL.dwg, create viewports using named views
5. Updates: Change design drawing, DATA Shortcut updates, MODEL updates, reload xrefs in sheets, all sheets show changes

Advanced Techniques

Multiple Model Files:

For very large projects:

• Create MODEL-Phase1.dwg, MODEL-Phase2.dwg, etc.
• Or MODEL-North.dwg, MODEL-South.dwg for geographic divisions
• Each references relevant Data Shortcuts for that area
• Keeps file sizes manageable

View Templates:

• Create standard view sizes for common sheet scales
• Example: 24"x36" sheet at 1"=50' scale = specific view area size
• Draw rectangles as templates, use to define view boundaries consistently

Best Practices

MODEL.dwg Management:

• Keep MODEL.dwg in 04_Design/Model/ folder
• Reference only—never copy design objects into MODEL
• Organize annotations on logical layers
• Use consistent text styles and label styles
• Save regularly and archive major versions

Performance:

• MODEL.dwg can get large—manage layers and purge regularly
• Consider xref clipping if only portions of design needed
• Turn off automatic Data Shortcut synchronization during heavy annotation work
• Close unnecessary xrefs when not needed

Case Study: One MODEL.dwg Serves 40 Sheets Effortlessly

A mixed-use development project with 40 sheets used a single MODEL.dwg referencing all design elements. Named views were created for each sheet. When design changes occurred mid-project, MODEL.dwg was updated once and all 40 sheets reflected changes upon xref reload.
