Supports Autodesk Civil 3D 2025, 2026, and 2027.

SheetAgent for Civil 3D never modifies your manual work. It flags drift in a health panel and lets you decide what to accept or revert. Your drawings stay yours.

A plan and profile sheet built by SheetAgent for Civil 3D: plan viewport, profile viewport, key map, and a title block numbered C4-01.

A complete sheet set, on your standard.

Everything stays dynamic: change anything as your design evolves, never rebuild.

  1. Main viewport: single plan, or multi-VP (plan+plan, plan+profile, plan+duplicate)
  2. Profile split, horizontal: one profile view per sheet, kept in sync with your plan view
  3. Profile split, vertical (datum): for hilly terrain and big grade changes, each segment on its own datum at the scale you chose
  4. Both splits: your main profile is never touched, the labels you placed on it carry over, and they work wherever the profile lives, in an Xref or the current drawing
  5. Support viewports: key maps, legends, vicinity maps
  6. Key maps: tile outlines, hatched extents, sheet-number labels
  7. Matchlines: lines and labels, trimmed at viewport edges
  8. Title block: placed, populated, sequenced per sheet
  9. Layer standards: colors, line types, names, every layout
  10. Annotations: north arrow, scale bar, station ranges
  11. PDF detail import: batch external pages into complete sheets
  12. Project keyplans: live overview of every sheet across all subsets
  13. Live editing tools: apply layers across viewports, change hatches at a glance, trim matchlines, adjust layouts
  14. Project Control: one tiling shared by every discipline, files split at the count you choose, match lines and numbering carried across them

Configure. Preview. Build.

Configure each layout in the panel. Preview the result. Build when it's right.

A plan + profile sheet, built in under two minutes. (Video shortened for the page.)

Same workflow for every layout type: Single viewport · Multi VP (plan+profile, plan+plan, plan+duplicate) · PDF detail import · Project keyplans

For CAD managers.

The three questions every standards-conscious team asks before adopting a plugin.

Importing company standards: SheetAgent for Civil 3D panel, Excel template with layer names and color names, and the CAD command line confirming "Company Standards successfully loaded."

Set the standard. Keep it current.

A CAD manager edits one Excel template: layers, colors, line types, viewport defaults. Every layout every user creates is on standard. Change the template later, and the health palette flags every layout that's drifted; one click restandardizes them all.

Configure in Excel: minutes, not hours
Applied automatically to every layout type
Standard changes? Health flags it. Standardize is one click.
Every user, every project, zero deviation
SheetAgent for Civil 3D Adopt Existing Layouts dialog: template elements auto-detected, layouts auto-matched with user override controls.

Works on legacy drawings.

Layouts built before SheetAgent for Civil 3D was installed become SheetAgent-ready in a few clicks. Once adopted, they're managed like any other: health palette, layer standards, all tools apply fully.

Adopt existing layouts in a few clicks
No rebuild needed: your work stays
Full editing capability, same as new layouts
SheetAgent Health palette detecting geometry mismatches, missing scale bars, layer drift, north arrow rotation, and more, surfacing issues without blocking the designer.

Warns. Never blocks.

The health palette flags drift, missing elements, and edits, but never forces a change. Fix it, leave it, or come back to it later. Designer always in control.

Detects drift, missing standards, model changes
Surfaces issues with explanations
Designer decides what to accept or revert

Four ways to generate a single-viewport sheet.

Pick the mode that fits the project. The tile stays editable either way.

Array
Tile a closed boundary: limits of work, sites, parcels.
Path
Run sheets along a polyline: exhibits, utilities, early studies before an alignment exists.
Alignment
Sheets follow stationing: the workhorse for production plan sets.
Free placement
The sheet preview follows your cursor in model space. Click to drop it where you want.

Take everything above and control the whole project from one drawing.

One control drawing holds the tiling. Every discipline inherits it, every file stays in sync, and the numbering runs straight through the whole project.

One control drawing, every discipline, every file. Built once, then kept in sync as the project changes.

One tiling, every discipline
Demolition, erosion control, grading and layout are created from a single definition, with the viewports already located and sized. Move a tile in the control drawing and every discipline that inherits it follows, with no manual rework.
Files split before they get heavy
You choose the maximum layouts per file. As one example, thirty layouts with the maximum set to eight becomes four files, and match lines carry across every boundary: an edge sheet reads SEE C2-109 for a sheet that lives in the next drawing.
Sectors on large projects
Define sectors and each gets its own key map alongside one for the whole project. Numbering runs straight through rather than restarting per file or per sector. There is no limit on disciplines, files, sectors or sheets.
