Plan and Profile Sheets: The Centerpiece of Road Projects
Plan and Profile sheets combine horizontal (plan) and vertical (profile) views on a single sheet—essential for road, trail, and utility projects. These sheets show the relationship between alignment geometry, existing ground, proposed grades, and design features.
Components of Plan & Profile Sheets:
- Top Viewport: Plan view showing alignment, stationing, features
- Bottom Viewport: Profile view showing EG, FG, elevations, grade slopes
- Station Match Line: Vertical line connecting plan and profile at same station
- Annotations: Station labels, curve data, slope percentages, elevations
Creating Plan & Profile Sheets
Method 1: Manual Layout
- Create sheet with two viewports stacked vertically
- Top viewport: Plan view from MODEL.dwg using named view
- Bottom viewport: Profile view from alignment's profile view
- Align stations between viewports
- Set appropriate scales (plan: 1"=50', profile: 1"=50' H, 1"=5' V typical)
Method 2: Create View Frames (Plan Production Tools)
- Civil 3D's Plan Production tools automate this process
Output tab > Plan Production > Create View Frames- Select alignment, specify sheet layout settings
- Civil 3D creates view frames along alignment at sheet intervals
Create Sheetsgenerates all sheets automatically with plan/profile views- Sheets reference view frames for consistent station ranges
Plan Production Tools Advantages:
- Automated sheet creation for entire alignment
- Consistent station ranges across sheets
- Automatic match lines between sheets
- Updates when alignment changes
- Professional, uniform appearance
Quality Assurance & Quality Control (QA/QC)
Before delivering any project, systematic QA/QC prevents costly errors and ensures professional quality.
Design QA Checklist:
- Surfaces:
- EG surface matches survey—spot-check elevations at benchmarks
- No spikes or artifacts in surface triangulation
- Breaklines in correct locations
- FG surface ties into EG properly at limits
- Alignments:
- Curve radii meet minimum standards
- Tangent lengths adequate
- Ties into existing features correctly
- Station equations correct (if used)
- Profiles:
- Grades meet minimum/maximum standards
- Vertical curve lengths adequate for sight distance
- Matches existing grades at tie-ins
- Adequate clearance over utilities
- Corridors:
- Assembly appropriate for each region
- Targets set correctly
- Daylight slopes meet standards
- No gaps or overlaps in corridor surface
- Pipe Networks:
- Minimum slopes met
- Adequate cover over all pipes
- No conflicts with other utilities
- Inverts calculated correctly
Sheet QA Checklist:
- Title Blocks: All fields filled, correct project info, dates current
- Sheet Numbers: Sequential, match sheet index
- Scales: Correct and noted on each sheet
- North Arrows: Present and oriented correctly
- Legends: Match sheet content
- Labels: Readable, no overlaps, correct data
- Xrefs: All loaded, no missing references
- Line Weights: Appropriate hierarchy (bold for proposed, lighter for existing)
Common QC Checks:
- Visual Review: Print or view all sheets, scan for obvious errors
- Coordinate Review: Have another team member review design and sheets
- Client Standards: Verify compliance with local/client requirements
- Calculations: Spot-check quantities, elevations, slopes
- Consistency: Uniform appearance across all sheets
