Takeoff - Overview

Linarc’s Takeoff feature lets you measure directly from plan drawings using simple, intuitive markup tools. Highlight areas or elements with line and shape tools and instantly see key dimensions. If the drawing lacks a scale, a quick one-time calibration ensures accurate measurements.

• Measure directly from plan drawings using line and shape markups.
• Automatically view dimensions such as length, width, perimeter, and area when a printed scale is detected.
• Perform a one-time manual calibration if the sheet has no clear scale or includes multiple drawings with different scales.
• Save, label, and manage takeoff markups throughout the project lifecycle.

Calibration

Drawings often come in various scales, so calibration ensures accurate measurements.

• Automatic Calibration - Linarc’s AI scans each plan sheet for a visible printed scale. If found, it applies the scale automatically and displays a scale indicator when you open the sheet. Any markup you place instantly shows its dimensions.
• Manual Calibration - If the scale is missing, unclear, or varies across multiple drawings on the same sheet, you can calibrate manually. It’s a one-time setup per sheet. Once saved, all line and shape markups will show accurate dimensions. For manual calibration steps, see here.

Measuring Areas and Lengths

• Use markup tools—rectangles, squares, circles, ellipses, triangles, and straight lines—to define the area or length you want to measure.
• Each markup automatically displays calculated dimensions such as length, width, perimeter, and area.
• Add labels to represent specific takeoff items for easy classification and review.
• All saved takeoff markups remain accessible on the plan sheet or in a dedicated management screen, where you can review, edit, or export quantities anytime.
