Identify the issue

Beam deflection is 6.79 mm, above the 6.00 mm limit for this example.
STRUCTURE CUBE / PRODUCT / V3.0.4
Structure Cube is MEIGONA's Windows software for prefabricated and welded building-services supports and hangers: modelling, structural checks, material schedules and calculation reports.
01 / MODEL & LOAD
Follow a prefabricated support with three water pipes. Match the arrangement, span and loads.
SELF-BUILT DEMO / INPUTS
| Pipe | From beam start | Design load |
|---|---|---|
| DN80 | 300 mm | 428 N |
| DN100 | 750 mm | 577 N |
| DN150 | 1200 mm | 1,122 N |
Pipe selections determine the displayed design loads. Member self-weight is also included. Check each input against the arrangement.
02 / CHECK & SIZE
Identify the issue

Beam deflection is 6.79 mm, above the 6.00 mm limit for this example.
Run smart sizing

Smart sizing selects a C41D beam; deflection reduces to 1.21 mm.
Pipe sizes, positions, span and support spacing stay the same. Sizing also updates the matching connector configuration and member self-weight. Maximum utilization changes from 113.20% to 29.10%.
03 / REPORT DELIVERY
Follow one self-built teaching case from model and load inputs to structural checks and calculation report output. Enlarge the actual Chinese and English cover, design-basis and arrangement excerpts.
Free Edition provides unlimited watermarked PDF and no Word. Enterprise-native projects allow Word and watermark-free PDF; free-project restrictions remain. Formal delivery requires review of the complete report.

Current main-application captures use actual V3.0.4 Free Edition controls in Light mode with isolated self-created data. Both cases were reloaded and calculated; smart sizing was executed for the prefab case. Free Edition supports watermarked PDF only; enterprise outputs are verified separately using an enterprise build. These are not customer projects or independent engineering reviews.
Public material is limited to physical arrangements, pipe inputs, result headers and cover, basis and arrangement excerpts from the same cases. Internal models, source code, force diagrams, connection parameters and full reports are excluded. Project conclusions require professional review of complete inputs and reports.
