How to Do Calculations in Bluebeam Revu?

Bluebeam Revu lets you perform automatic calculations within PDF forms, which is especially useful for technical or administrative tasks. If you need to add, multiply or perform any operation between form fields, follow these steps to configure the calculations correctly:

Steps to perform calculations in forms

1. Access the form tools
   • Open your PDF file in Bluebeam Revu.
   • Go to the top menu and select Tools > Forms > Form Editor, or open the Forms panel directly from the side panel
     
2. Create the necessary fields
   • Add the form fields that will hold the numeric values you want to use in the calculation.
   • To do this, select the field type (for example, Text Box) from the Forms panel and place it in the desired location on the PDF.
     
3. Create a field for the result
   • Next, create a third field that will show the result of the calculation.

   • Select it to configure it in the following steps.

     

4. Access the field's properties
   • With the field selected, go to the Properties panel.

   • Scroll down until you find the Calculate tab.

     

5. Configure the calculation type
   • In the Calculation Field section, select the type of operation you want to perform. For example, to multiply, choose Product.

   • Click Select to choose the fields that will take part in the calculation.

     

6. Select the fields involved
   • Tick the two fields (or more) that contain the values you want to use in the operation.
   • Click OK to confirm.

     

Important considerations
Bluebeam Revu only detects numbers within the fields, ignoring text, as long as they're grouped together. For example:

• In "46abc" or "x=46", the number 46 will be detected as a valid value.
• On the other hand, if the content is a mix of numbers and letters such as "ag4xrf6ht", the system won't interpret the value correctly, which can cause errors in the calculation.
