Profile Rule Examples

1. Overview
   
2. Fixed Material by Profile family
   
3. Prefix by Radius
   
4. Length by Profile depth
   
5. Grating Material substring match
   
6. CHS Material by depth and thickness
   
7. CHS fallback Material rules with onFirstMatch
   
8. CHS Length override rules with onAnyMatch

CHS Material by depth and thickness

---

Problem

CHS sections do not use a single material rule.

The permitted grade depends on both the depth and wall thickness extracted from the profile.

Some sizes are available only in 250, some only in 350, and some are available in both. Where both are available, 250 may be preferred while 350 is still acceptable.

Strategy

Use one CHS regex Match to extract the key profile values, then apply many MATERIAL Targets with Conditions based on both depth and thickness.

This approach avoids duplicating the same regex logic repeatedly.

Rule Structure

Subject

PROFILE

Match

Regex extracting CHS depth and thickness

Target

MATERIAL

Conditions

use depth and thickness match groups together

Minimal Tree

Subject: PROFILE
  Match: Regex (CHS)
    Target: MATERIAL
      Condition: depth = X and thickness within range A
    Target: MATERIAL
      Condition: depth = X and thickness within range B
    Target: MATERIAL
      Condition: depth = Y and thickness within range C

Why This Pattern Is Useful

This is the clearest example of Conditions being used to build a decision table.

The regex provides the raw inputs. The Conditions interpret those inputs. The Targets define the valid material outcome.

Example Results

Profile	Depth	Thickness	Material	Result
CHS139.7*4.0	139.7	4.0	350	Okay
CHS139.7*4.0	139.7	4.0	250	Error
CHS139.7*5.0	139.7	5.0	250	Okay
CHS139.7*5.0	139.7	5.0	350	Info

Why Info Can Be Useful Here

Where both grades are available, a result of Info can be used to show that an alternate acceptable grade exists while still indicating that another option is preferred.

This is a good example of using severity levels for guidance, not just pass/fail control.

Notes

This rule set is intentionally more complex than most profile examples.

It is a good reference whenever a rule depends on:

• more than one extracted regex value
• many conditional targets on the same cell
• preferred vs alternate acceptable values
