Measure-type variants: arithmetic expression support

This article explains the enhanced behavior of measure-type variants in 3CAD Next. You can now enter arithmetic expressions (e.g., 20 + 20) in measurement-type fields, and the system automatically calculates and applies the result, respecting all existing rules and constraints.

This enhancement improves usability for users who work with calculated dimensions.

Key benefits

• Arithmetic expression support
  Enter formulas such as 50 + 25 or 600 / 2, and the field evaluates the result immediately.
   
• Min/Max constraint enforcement
  Calculated results always respect the configured measurement range.
   
• Improved multi-unit handling
  Works with metric and imperial systems, even when sliders are available.
   
• Safe handling of empty inputs
  If the field is left empty and confirmed, the value defaults to 0 or to the minimum configured value (if greater than 0).
   

• More predictable behavior
  Consistent across all supported measure variants, including complex or slider-based inputs.

   

How it works

1. In 3CAD Next, open an item with a measure-type variant (e.g., width, depth, or height).
    
2. Type an expression, for example 20 + 30.
    
3. Press Enter.
    
4. The system calculates and applies the result within allowed limits. 
    

Behavior for empty inputs

If the measurement field is left empty and confirmed, the value becomes 0 (or the configured minimum if greater than 0).
