Dimension Tool
Measure distances and create dimension lines on construction drawings.
Introduction
The Dimension Tool is a powerful PDF measurement tool that allows you to measure distances directly on a PDF drawing. With this Deta Studio PDF measuring, you can check dimensions on the spot while reviewing a document, making it easy to add dimensions to PDF drawing files. This measuring tool for designers, engineers, and builders is especially helpful when you need a quick sense of dimensions to support comments, markups, or design decisions without switching to another PDF markup tool or reference.
Note: Before creating measurements, ensure the drawing scale in Deta is set correctly so the displayed dimensions are accurate. The scale can be adjusted at the bottom of the screen.

Step 2: Move or Adjust the Dimension
After the dimension is created:
- Adjust measurement points: Click and drag the dimension points to reposition them. The measurement value will update accordingly.
