Section Designer — section properties
section_propertiesUse for a new section's computed properties before writing it. For an existing section's stored properties use section_read. Computes the full CIVIL NX property set of a section with Section Designer's solver: exact area, centroid, second moments, extreme fibres and perimeters from the outlines, and torsion J and shear areas ASY/ASZ from a finite-element mesh refined until all three settle to 0.5 % (converged: true). Composites (two or more parts) give each part alone (STIFF) and each construction stage transformed to the reference material (STIFF_SUM). Results use CIVIL's names (AREA, ASY, ASZ, RXX = J, RYY = Iyy, RZZ = Izz, …) in the section's units. Needs no model. Same section input as section_preview.

| Name | Required | Description | Default |
|---|---|---|---|
| drawing | No | Also return the drawing (with the computed centroid). | |
| section | Yes | The section, read off the sketch. Axes: y across (positive right), z up, as seen in CIVIL's section dialog; put the origin anywhere convenient (e.g. bottom-left corner or soffit centre) — CIVIL's frame is applied on write. |
