Geometry
Derived model geometry — member and plate positions, lengths, areas, centroids and local axes (no analysis run required)
List Member Geometry
Lists derived geometry for members: node ends (analytical), physical (offset-adjusted) point ends, physical length and the local coordinate system. Supports the standard member filters and offset/limit pagination; results are sorted by member Id ascending and pagination metadata is returned in response headers (Total-Count, Offset, Limit). Members whose end nodes are missing, or whose frame cannot be computed (degenerate geometry), are omitted from the response.
query Parameters
membersMember Ids to filter by, in SG list format (e.g. "1,3-7,10").
Omit to return all members.
typeFilter by member type (Normal, TensionOnly, CompressionOnly, Cable, Gap, BrittleFuse, PlasticFuse).
Member element type. Determines the structural behavior of the member. Maps to SPACE GASS lookup table "Member Type".
sectionFilter by section number.
materialFilter by material number.
offsetNumber of items to skip from the start of the result set. Default is 0.
limitMaximum number of items to return. Default is null (return all).

Returns the list of member geometry
memberThe member this geometry belongs to.
A lean reference to a node — its Id and coordinates only. Used to embed a node's identity
and position in derived-geometry responses without dragging in the node's sub-resource
indicators (restraints/constraints). The id matches the node's Id in
GET /job/structure/nodes.
A lean reference to a node — its Id and coordinates only. Used to embed a node's identity
and position in derived-geometry responses without dragging in the node's sub-resource
indicators (restraints/constraints). The id matches the node's Id in
GET /job/structure/nodes.
A 3D point with X, Y, Z coordinates.
A 3D point with X, Y, Z coordinates.
lengthPhysical (offset-adjusted) member length — the distance between pointA and
pointB. The analytical node-line length is the distance between nodeA
and nodeB.
A local coordinate system (LCS): an origin plus three local axis unit vectors expressed in global coordinates. The axes form a right-handed orthonormal basis — the columns of the element's local-to-global transformation matrix.
Get Member Geometry
Gets the derived geometry for a single member: nodeA/nodeB (the analytical
end nodes — identity and position), pointA/pointB (the physical,
offset-adjusted ends), the physical length and the physical localAxes
frame. nodeA/nodeB equal pointA/pointB when the member has
no offsets.

List Plate Geometry
Lists derived geometry for plates: corner nodes (analytical), physical (offset-shifted) corner points, area, perimeter, centroid and the local coordinate system. Supports the standard plate filters and offset/limit pagination; results are sorted by plate Id ascending and pagination metadata is returned in response headers (Total-Count, Offset, Limit). Plates whose corner nodes are missing, or whose frame cannot be computed (degenerate geometry), are omitted from the response.
query Parameters
platesPlate Ids to filter by, in SG list format (e.g. "1,3-7,10").
Omit to return all plates.
theoryFilter by plate theory (Kirchoff or Mindlin).
Plate theory type for finite element analysis. Maps to SPACE GASS lookup table "Plate Theory".
materialFilter by material number.
offsetNumber of items to skip from the start of the result set. Default is 0.
limitMaximum number of items to return. Default is null (return all).

Returns the list of plate geometry
plateThe plate this geometry belongs to.
The plate's corner nodes in order (A, B, C[, D]) — identity and position. Three entries for a triangular plate, four for a quadrilateral.
Physical (offset-adjusted) corner positions in order (A, B, C[, D]), in global coordinates — each corner shifted along the plate normal by the offset.
areaPlate surface area.
perimeterPlate perimeter — the sum of the edge lengths.
A 3D point with X, Y, Z coordinates.
A local coordinate system (LCS): an origin plus three local axis unit vectors expressed in global coordinates. The axes form a right-handed orthonormal basis — the columns of the element's local-to-global transformation matrix.
Get Plate Geometry
Gets the derived geometry for a single plate: nodeCorners (the analytical corner
nodes), pointCorners (the physical, offset-shifted corners), area,
perimeter, centroid and the localAxes frame (local Z is the plate
normal). Corner and centroid positions are shifted along the normal by the plate offset.
