By civil engineers, for civil engineers

Complete layouts.
Your exact standards.
Every time.

Designer-friendly. Manager-approved.

The Civil 3D plugin that builds your full sheet set. New drawings or existing. Always on standard.

Supports Autodesk Civil 3D 2025 and 2026.

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.

What the panel builds

A complete sheet set, on your standard.

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

Main viewport: single plan, or multi-VP (plan+plan, plan+profile, plan+duplicate)
Support viewports: key maps, legends, vicinity maps
Key maps: tile outlines, hatched extents, sheet-number labels
Matchlines: lines and labels, trimmed at viewport edges
Title block: placed, populated, sequenced per sheet
Layer standards: colors, line types, names, every layout
Annotations: north arrow, scale bar, station ranges
PDF detail import: batch external pages into complete sheets
Project keyplans: live overview of every sheet across all subsets
Live editing tools: apply layers across viewports, change hatches at a glance, trim matchlines, adjust layouts

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. Beta

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. Adoption is in beta; we are still testing it across drawing styles.

Adopt existing layouts in a few clicks
No rebuild needed: your work stays
Full editing capability, same as new layouts
SheetAgentHealth 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.

What it saves on a project.

Conservative time savings at a $100 billable hour rate.

$900–$1,300

$2,200–$3,300

$7,300–$11,000

Small project

12 sheets

Medium-large

30 sheets

Large project

100 sheets

These numbers only count layout build and update time. They exclude time saved on layer management, support viewports, key maps, legends, PDF imports, and exhibit workflows. Actual savings are significantly higher.

You see what we see.

The same Reports page every customer gets: every number computed per command, from their own seats' telemetry.

manage.setline.ai / demo Example dashboard

A glimpse of the manager portal: every command in the catalog has a published minutes-per-run estimate, multiplied by what your seats actually ran. No averages, no vendor approximations, just your team's telemetry. The full experience is in the actual portal.

It's also where your company controls access: every seat is assigned by your own manager, and nobody can run SheetAgent, inside or outside your firm, without their say-so.

One firm. Eight weeks. 186 hours back.

A California civil engineering firm ran SheetAgent on live project work: five seats, real deadlines, real clients.

“We produced 105 sheets in 4 days, counting several iterations and edits while learning how to use the tool.”
Project engineer at the firm, during the trial
The cross-check that matters. During the trial, the firm's engineers estimated their own time savings, before seeing any telemetry. Their estimate and the telemetry-based calculation landed in the same range, independently.
Numbers, not testimonials. Every figure above comes straight from the customer's Manager Portal report, the same per-command reporting every customer gets. The firm asked not to be named; the data speaks for itself.

Estimated hours = command runs × published minutes-per-run, summed across value-bearing commands over a eight-week period in spring 2026. Excludes layer management, support viewports, key maps, and exhibit workflows. Actual savings are higher.
