Cross-Section Drawing

Each optimization result includes a 2D vector drawing of the cross-section.

What's Shown

The drawing displays:

• Overall dimensions — total width, total depth, flange thickness
• Flange and web proportions — drawn to scale
• Reinforcement layout — actual positions of:
  • Prestress strands (circles, positioned per the optimization)
  • Passive rebar (if applicable)
• CIP topping — shown as a separate layer if a composite design is used
• Number of stems — the full multi-stem cross-section (single-T, double-T, or multi-rib)

Reading the Drawing

The section is drawn looking at the beam end-on (cross-section view):

• The flange is the wide horizontal portion at the top
• The stems (also called ribs or webs) extend downward
• Strand positions show the actual vertical distribution within each stem
• Dimensions are labeled in mm (or inches if imperial units are selected)

Design Geometry Variables

The optimizer controls these geometry parameters within your mold constraints based on your selections:

• Total depth
• Flange thickness
• Stem width (upper and lower)
• Number of stems

The section drawing reflects the actual optimized values, not the mold's maximum envelope.
