How to Change the Measurement Units and Drawing Scale

Scaled drawings represent real-world objects at a reduced or enlarged size while maintaining accurate proportions. Floor plans, maps, engineering drawings, and technical blueprints are common examples of scaled drawings.

Scaled drawings use measurement units to define the dimensions of objects. Depending on the project, you can work with metric units such as meters, centimeters, and millimeters, or imperial units such as yards, feet, and inches.

ConceptDraw DIAGRAM makes it easy to select the appropriate measurement units and scale for your drawings. Each document can have its own scale and measurement system, allowing you to create a wide variety of professional diagrams and plans.

1. Open the ConceptDraw DIAGRAM document for which you want to change the drawing scale.
2. From the File menu, select Document Properties, and then open the Units tab.
3. Click Pre-defined Scale, and choose the appropriate metric, architectural, or civil engineering scale. You can also select Custom Scale and enter your own scale values.

4. The document rulers display the current measurement units in the upper-left corner of the page. You can quickly change the document units by clicking the unit indicator and selecting a different option from the drop-down list.
   
   Note: You can choose pixels as the measurement unit; however, a pixel is not a true unit of measurement. It represents a screen dot, and its physical size varies depending on the display. When measurements are set to pixels, object dimensions are only accurate for the current screen type.

5. Optionally, you can modify an object's dimensions using the Shape Size boxes, which can be enabled from the View menu, or by using the Size section of the Arrange & Size panel.

Result: You can easily configure the scale and measurement units of your ConceptDraw DIAGRAM documents, ensuring accurate dimensions and professional results for floor plans, maps, engineering drawings, and other scaled diagrams.
