Rounding dimensions to one decimal place

In AutoCAD and Plant 3D projects, it can happen that dimensions are output with three decimal places by default. This guide explains how to adjust the precision of the dimensions in your drawings to obtain a clearer representation with only one decimal place.

Prerequisites

  • The relevant ortho or Module 4 drawing is open in AutoCAD / Plant 3D.
  • You have basic knowledge of using AutoCAD commands.

Step-by-step guide

  1. In the command line, enter the command BEMSTIL (or DIMSTYLE for the English version) and confirm with Enter to open the Dimension Style Manager.
  2. In the list on the left side, select the currently used style (e.g. Standard or ISO-25).
  3. Click the Modify... button on the right side.
  4. In the new window, switch to the Primary Units tab.
  5. Locate the Precision field and change the value there from 0.000 to 0.0 (or the desired number of decimal places).
  6. Confirm your changes with OK and close the manager via the Close button.

Result: The dimensions in your drawing are now automatically rounded to the selected number of decimal places (e.g. "123.456" becomes "123.5").

Important notes

  • Automation: This setting is controlled by AutoCAD/Plant 3D and is not influenced by the SuCri software.
  • Use templates: To set this permanently for all new drawings, you should make the change directly in your project templates (.dwt files).
  • Project-specific styles: If different precisions are required for different customers, it is advisable to create separate, meaningfully named dimension styles.

Troubleshooting

If the dimensions do not update immediately, enter the command REGEN in the command line to regenerate the drawing display.
