Step 1: Select the Alignment
Open your drawing in Civil 3D.
Click on the alignment for which you want to extract the curve directions.
This should highlight the alignment.
Step 2: Open Alignment Grid View
Go to the Alignment contextual ribbon.
Follow this path:
Alignment → Geometric Editor → Alignment Grid View
Click Alignment Grid View.
This opens a table showing:
- Tangents
- Curves
- Spirals (if any)
Step 3: Show the Clockwise Column
Inside the Grid View, look for a column called Clockwise.
This column tells whether the curve is:
- Clockwise
- Counterclockwise
Example:
-
True= Clockwise -
False= Counterclockwise
or sometimes it directly shows text.
According to your transcript, this feature is available in Civil 3D 2022.1 update.
Step 4: If the Column Is Missing
If you cannot see the Clockwise column:
Right-click on any column heading in the grid.
A list of columns will appear.
Tick Clockwise
This will turn the column ON.
Step 5: Select All Data
Click the first row.
Then hold Shift
Click the last row
This selects all alignment elements.
Alternative:
Right-click inside the grid and choose:
- Copy Selected
- or Copy All
I recommend Copy All.
Step 6: Paste into Excel
Open Excel
Click cell A1
Paste the copied data using:
Right Click → Paste
or
Ctrl + V
Now all grid data will appear in Excel columns.
Step 7: Keep Only Required Columns
Delete unnecessary columns and keep only these:
- Entity Type
- Radius
- Start Station
- End Station
- Clockwise
Recommended report columns:
| Curve No | Radius | Start Ch | End Ch | Direction |
|---|---|---|---|---|
| C1 | 725 | 420.18 | 520.18 | Clockwise |
This makes it cleaner.
Step 8: Remove Tangent / Line Rows
The pasted data will include lines/tangents as well.
We only need curves.
Sort the Entity Type column.
In Excel:
Home → Sort & Filter → Sort A to Z
Choose Expand Selection
This is important.
Step 9: Delete Non-Curve Rows
Delete rows that contain:
- Line
- Tangent
- Spiral (if not needed)
Keep only rows where the type is:
Curve
Now your report becomes a pure curve direction report.
Step 10: Final Clean Report
Your final table should look like this:
| Curve | Radius | Start Station | End Station | Direction |
|---|---|---|---|---|
| Curve 1 | 725 | 420.18 | 520.18 | Clockwise |
| Curve 2 | 700 | 520.18 | 620.18 | Counterclockwise |
