# SheetAgent for Civil 3D by Setline Build a complete sheet set in one pass. Keep it correct when the design changes. Bring your existing drawings along instead of starting over. SheetAgent for Civil 3D is a focused layout tool for Autodesk Civil 3D 2025 and 2026. It does one job, does it simply, and a civil designer can learn it in minutes. It is built by Setline, Inc., a software company in San Francisco, and is tested daily on real civil infrastructure projects. ## What it does SheetAgent for Civil 3D builds two kinds of main sheets: single-viewport sheets (one main plan viewport, such as grading or site layouts) generated four ways (array, path, alignment, or free placement), and multi-viewport sheets that pair main viewports (plan and plan, plan and profile, plan and duplicate). SheetAgent also adds support viewports (legends, keynotes, key maps) to any sheet. It also imports PDF pages from any document, sorts and assembles them into layouts, builds project keyplans for multi-file coordination, and splits profile views so early-stage profile work carries forward, with split profile views staying synced to the main design profile and to the plan views. Every tile stays editable in model space after generation. Move, rotate, or reshape a tile and the layout follows. Edit shared layout behavior once on the canvas and apply it across the whole set, instead of repeating the same fix sheet by sheet. Viewport titles, matchlines, profile views, support views, and standards stay linked as the design evolves. Sheet production is not a one-time event. A set gets built, the design moves, the set has to follow, and someone has to catch what drifted before it ships. SheetAgent handles that whole arc: build the set in one pass, edit it freely afterward, update it against new geometry instead of rebuilding, and audit it for drift with the Health dashboard before the set ships. It works on new drawings and on sheets that were drafted by hand long before the tool arrived. That is the difference between a set that is generated once and forgotten, and a set that stays honest for the life of the project. ## Simple, with minimal training Every main command opens a dedicated dialog with labeled sections, named fields, units shown inline, and guidance right where the input is (for example, the maximum value for a given scale shown next to the field that needs it). A designer fills the dialog, clicks Apply, and sees the result on screen. There is nothing to memorize, no command-line sequences, and no dynamic input prompts to read. The practical effect is that bringing a new user up to speed takes minutes, not hours, and input errors drop because the dialog tells the user what each field expects. ## New drawings or existing ones SheetAgent for Civil 3D works on a fresh model and on sheets that were drafted by hand long before the tool arrived. Adopt Existing Layouts, currently in beta, scans a manually produced drawing, detects its main viewports, support viewports such as legends and key maps, and title block attributes, then brings the drawing under the SheetAgent data model. From that point, Build, Update, and Health all work on it. Firms do not have to abandon legacy projects to get the benefit. Adoption is in beta while Setline tests it across drawing styles. ## Core capabilities - **Four sheet-generation modes**: array (tile a closed boundary), path (run sheets along a polyline), alignment-based (sheets follow stationing), and free placement (click-to-preview anywhere in model space) - **Editable tiles in model space**: move, rotate, reshape, or adjust coverage after generation; the layout follows the tile - **Layout canvas**: edit shared layout behavior once and apply across the managed set, instead of repeating the same fix sheet by sheet - **Single viewport plan sheets** with array, path, alignment, and free placement modes - **Multi-viewport sheets** with plan and plan, plan and profile (multiple alignments supported), and plan and duplicate sub-modes - **PDF Details import** to build sheets from existing PDF pages - **Key Plans** for multi-file project coordination, using a control drawing that aggregates subset DWGs - **Matchlines** that are dynamic and redraw automatically whenever a tile changes, with no manual approve or reject step - **Keymaps** that highlight the current tile on each sheet, with hatch and label control - **Support Blocks**, north arrow and scale bar, placed and auto-scaled per viewport - **Support Viewports** for repeating content such as legends, created per sheet - **Title Block automation** with Sheet Set Manager field detection - **Sheet Set Manager integration** with creation and bidirectional sync - **North arrow intelligence** with verify, accept, and revert controls - **Viewport trim at matchline** using pure undo, with no destructive edits - **Renumber** for non-destructive sheet renumbering - **Adopt Existing Layouts** (beta) to bring hand-drafted sheets under management for Build, Update, and Health - **Company Standards**, a downloadable XLSX where a CAD manager defines the firm's layer names, colors, and linetypes once. SheetAgent applies them to every layout it produces. Setup takes about two minutes - **Dialog-driven configuration** for every command - **Full dynamic edits**, so any action can be revised after the fact without redoing prior work - **Layer control that respects ownership**: the tool standardizes the layers it creates and never overrides layers a user made or edited by hand - **Health dashboard** with contextual remediation actions - **CSV import** for bulk sheet definitions ## Return on investment Early trial telemetry indicates on the order of 95 labor hours saved per seat per year. Valued at a $100 per hour loaded labor rate, that is roughly $9,500 per seat, several times the annual subscription at every tier. The figures are deliberately conservative. Per-command time savings are capped at 1 to 15 minutes and are not adjustable by the customer, so the per-command rate is a floor rather than an estimate. Total hours saved scale with each team's actual command volume, which the Manager Portal at manage.setline.ai computes live from real usage rather than a vendor projection. CAD managers set their own labor rate and see their own team's return. ## Field results (customer case study) A California civil engineering firm ran SheetAgent for Civil 3D on live project work over eight weeks in spring 2026, on five seats. Measured by Manager Portal telemetry: 1,952 command runs across 71 working sessions, 498 sheet layouts built, 273 layouts updated, and 1,941 layout audits. Estimated time saved was 186 hours, roughly $18,600 in billable time at a $100 per hour rate. During the trial period the firm's engineers independently estimated their own time savings, and their estimate landed in the same range as the telemetry-based calculation. These figures count only layout build and update operations; they exclude layer management, support viewports, key maps, and exhibit workflows, so actual savings are higher. The firm is not named because Setline customers consider the tool a competitive advantage and asked not to be identified; the numbers come directly from the same Manager Portal reporting every customer receives. The separately quoted figure of about 95 hours saved per seat per year is the conservative cross-customer floor; these case-study numbers reflect one firm's measured eight-week period. ## Pricing Sold as an annual subscription, priced per seat, with a marginal volume discount applied seat by seat: - Seats 1 to 25: $899 per seat per year - Seats 26 to 50: $799 per seat per year - Seats 51 to 75: $699 per seat per year - Seats 76 and up: enterprise pricing on request A 30-seat firm pays 25 x $899 plus 5 x $799, or $26,470 per year. A 50-seat firm pays $42,450. A 75-seat firm pays $59,925. Seats are transferable between users within an organization, with a 12-hour cooldown on reassignment. Annual expiry is unified across the organization, and additional seats are prorated to the renewal date. ## Trial A 15-day full-feature trial, no credit card and no contract, provisioned with up to 50 seats for evaluation. Trial requests are processed by company domain. ## Supported software - Autodesk Civil 3D 2025 - Autodesk Civil 3D 2026 SheetAgent for Civil 3D runs as a plugin inside Civil 3D and requires Civil 3D as the host application. It does not require design objects such as alignments, profiles, or corridors to be present. Array, path, and free placement modes work on geometry alone. Alignment-based modes use Civil 3D alignments when the workflow calls for them, but alignments are not a prerequisite for using the tool. ## Data and privacy SheetAgent for Civil 3D runs locally on the workstation and does not transmit drawing files, drawing content, or project data to Setline's servers at any time. Telemetry is limited to command names run, layout counts, plugin version, anonymous session identifiers, the email signed into the plugin, and diagnostic exception messages. ## Who it is for Civil engineering firms producing plan, profile, and detail sheets in Civil 3D. Typical users are drafters and designers. Typical buyers are CAD managers, IT leads, or project principals. Firm sizes from solo practitioners to multi-office enterprises are supported. ## Frequently asked questions The full FAQ is maintained separately as the single source of truth for questions and answers, on the FAQ page at https://setline.ai/faq.
