Roll Plots: How to Read, Print, and Take Off Roll Plans

What is a roll plot?

A roll plot is a plan sheet sized for a plotter roll rather than a fixed sheet size. The Federal Highway Administration’s Federal Lands CAD manual describes roll plots as printed from large plotter paper rolls and intended to show long stretches of roadway. Instead of twenty plan sheets joined at match lines, the corridor runs continuously from the beginning of the project to the end, or to the end of that roll.

Widths follow standard plotter paper. NYSDOT’s guidance uses 22, 34, and 44 inch widths; the FHWA manual lists 22, 34, 36, 40, and 42 inches as the most common roll widths; PennDOT’s workflow produces a 34 by 200 inch sheet. Length is capped at 200 inches in all three documents. That cap matches the default maximum PDF page size in the PDF standard, ISO 32000-1, which is 14,400 by 14,400 units, or 200 by 200 inches.

A roll plan does not replace every sheet. Typical sections, quantity tabulations, and details may still arrive as conventional sheets, or be placed in open space along the roll. Use the contract’s index of drawings to see which items live on the rolls and which live on separate sheets.

Why are DOTs switching to roll plans?

NYSDOT published Roll Plan Guidance in July 2025. It recommends roll plans for projects longer than 2,500 feet of station length, which it says typically consolidates four or more 11 by 17 drawings at a common drawing scale of 40. The listed advantages include placing plans, sections, and details together, removing match lines, title blocks, scale bars, and north arrows from each sheet, and continuous pan and zoom instead of flipping between sheets.

PennDOT runs a Roll Plan pilot under its Digital Delivery program. It describes the deliverable as a sheet-less 2D project model in a single PDF, or a digital roll plot, containing the items found in a traditional sheeted plan submittal. Its guidelines note that a pre-bid meeting may be held to answer bidders’ questions about the roll plan.

For bidders, the practical change is in how the documents arrive. NYSDOT posts roll plans as individual PDFs in a zip folder in the Plans section of the contract website, and splits the zip into volumes because posted files must be under 90 MB. Download every volume before you start the takeoff.

How do you view a roll plot PDF?

Open the roll in a PDF viewer and pan along the alignment instead of paging. Fit the width of the roll to the screen, then zoom in on the station range you are working. Keep a second view open beside it: NYSDOT recommends a split horizontal or vertical view so you can read details, tables, and typical sections while the plan stays on screen.

Use the navigation the designer built in. PennDOT’s guidelines require an index of PDF hyperlinks that includes each 1,000-foot station interval and state route intersections. NYSDOT suggests repeating scale bars, legends, and north arrows along the roll, with every 3 feet of roll length as a rule of thumb, so the nearest scale bar is rarely far from where you are reading.

If a roll opens or redraws slowly, layers may be the reason. NYSDOT notes that CAD reference files and levels come through as PDF layers that can affect how viewers process the file, and recommends flattening roll plans before distribution. A flattened roll loses its layer toggles, so keep the original file if you need to turn layers on and off.

How do you print a roll plot?

To print on 11 by 17 or letter paper without losing the drawing’s scale, use Zip Takeoff’s free roll plot converter. Stamp sheet frames along the roll at the print scale you pick, then export numbered sheets of the original vector linework with match lines, a graphic scale, and the printed scale on every sheet. It runs in your browser without an account.

A full-size print needs a plotter loaded with paper at least as wide as the roll. The FHWA manual says roll plots should be created at a conventional design scale, such as 1 inch = 40 feet, so scaled measurements can be made with a ruler on the printed roll. That only holds when the roll is printed at 100 percent.

To print a section on standard paper, select the area and print it at a custom scale. NYSDOT’s procedure uses the selected graphic option, a chosen paper size such as 11 by 17 or 22 by 34, and a custom scale percentage. The resulting scale is the original scale divided by the percentage: a 40-scale roll printed at 50 percent gives 40 ÷ 0.50 = 80 scale. Write the printed scale and the station range on each sheet so the pieces can be reassembled and measured later.

Without the converter, an office printer gives you three other ways to get the roll onto 11 by 17 or letter paper: tile the whole page with a PDF viewer’s poster option, print selected sections at a custom scale as above, or paste screenshots into a document, which loses the scale unless you measure and record it. The guide to printing roll plots on a standard printer covers each method, a worked sheet count, and the checks.

How do you do a takeoff on a roll plot?

In Zip Takeoff, open the roll like any other PDF page, set its scale from the title block or calibrate on a station interval, and measure areas, lengths, and counts into conditions, named measurement groups, by station range, with pay items attached for an Excel export. The steps below apply in any takeoff tool.

Start with an inventory. List each roll file, the station range it covers, its plot scale, and which items for your scope are on separate sheets. Profiles, typical sections, and tabulations may sit in different files from the plan view, and a long project can be split into several rolls.

Confirm the scale before measuring. Calibrate to the stated plot scale, then check it against the repeated scale bar nearest the area you are measuring, and against the stationing. On a straight section of the alignment, two station labels 100 feet apart should measure 100 feet. Profiles are usually drawn with an exaggerated vertical scale, so measure horizontal lengths in the plan view and read elevations and inverts from the profile labels instead of scaling them.

Work by station range. Split the corridor into ranges, for example each 1,000-foot interval that PennDOT links in its index, and keep each scope’s quantities grouped by range. Grouping lets you compare your totals with the tabulation sheets range by range and find a gap without remeasuring the whole roll. On a sheet that is 15 feet long, color or label each measured range so you can see where you stopped.

Example (illustrative): a 4,800-foot corridor drawn at 1 inch = 40 feet needs 4,800 ÷ 40 = 120 inches of roll, which fits within the 200-inch limit on one file. One 100-foot station interval measures 100 ÷ 40 = 2.5 inches on the full-size roll, and 1.25 inches on a section printed at 50 percent (80 scale). If your calibrated measurement of that interval is off, fix the scale before taking any quantity from that roll.

How do you find a location on a roll plot?

Use stations and offsets, the same as on a sheeted set. Jump to the nearest linked station interval or route intersection, then pan to the station you need. If the PDF has searchable text, search for the station label, structure number, or pipe run you are looking for. Text drawn as outlines will not be found by a text search, so fall back to the station links.

Where a curve is too large to fit the roll width, NYSDOT allows match lines, so check the ends of each curve for a match line note before assuming the roll is continuous.

How do you organize roll plots with the rest of the plan set?

Treat the index of drawings as the map of the contract. NYSDOT provides it as a spreadsheet crosswalk between the traditional index and digital delivery files. Rename or log each roll by station range and content, for example plan or profile, so the file list reads in order.

Keep the rolls, the conventional drawings, and any electronic files identified as plans in one project folder, and record which addendum each file came from. When an addendum reissues a roll, compare it against the version you measured before carrying any quantities forward.

How are roll plots created?

Designers produce roll plots from the 2D design model with custom sheet sizes. The FHWA manual prints each plot shape directly from the 2D design model. KYTC’s procedure in OpenRoads Designer generates the standard sheet cell, deletes it, and sets a custom size that encompasses the corridor, 36 inches high by 84 inches long in its example. NYSDOT provides sheet cells for 22, 34, and 44 inch widths. The source list below links each procedure.

Taking off roll plots in Zip Takeoff

Zip Takeoff opens roll plots like any other PDF page, up to the 200-inch page limit and 500 MB per upload. Oversized pages get a much larger render budget than standard sheets instead of being shrunk to a fixed size, so linework along a 15-foot roll stays readable when you zoom in. Each page has one scale: set it to the plan view’s plot scale, using title-block scale detection when a scale is found or manual calibration on a station interval when it is not. Search across the plan set finds station labels and structure numbers in searchable text. Group measurements into conditions by station range, attach pay items, and export quantities to Excel.

To print a roll on standard paper, the Roll Plot Converter on the Sheets tab stamps 11 by 17 or letter sheet frames along the roll at the print scale you pick, overlapping by half an inch. Export builds one PDF of the original linework, cropped as vectors when the source PDF allows, with match lines, a graphic scale, your takeoff on the sheets, and a legend of each condition’s quantity between that sheet’s match lines.
