Members

head: Header information of this component. This specifies the type and database index.
parent: The floorplan element the body has been converted from.
status: The properties of the body.
color: Refers to the default color of the body edges.
iumat: Refers to the default material of the body polygons.
xmin, ymin, zmin, xmax, ymax, zmax: The six coordinate data of the body’s bounding box.
nPgon: Number of polygons in the body.
nPedg: Number of edge references in the body.
nEdge: Number of edges in the body.
nVert: Number of vertices in the body.
nVect: Number of normal vectors in the body.
tranmat: The base transformation matrix.

Remarks

The 3D representation of a particular element is based on API_BodyType structure. One element may hold one or more bodies to describe the 3D geometry. Generally a body is built up from a number of vertices, edges, polygons and normal vectors. This data structure gives you the number of the internal components as well as some status bits, surface properties and a global transformation matrix. You also get a reference to the parent element through an API_Elem_Head structure.

You can get a component of a body, just after you call ACAPI_3D_GetComponent with the appropriate body component. Then you can obtain edges, pgons, vertices etc. of that body. Use indices from 1 to nPgon, nPedg, nEdge, nVert or nVect in parameter of ACAPI_3D_GetComponent function to get a subcomponent.

The status field specifies some properties of the body. You can use the bitwise-OR operator (|) to combine any of the following constants:

APIBody_MulRtxt: more textures are referenced by its materials.
APIBody_MulColor: more than one colors referenced by its edges.
APIBody_MulMater: more than one materials referenced by its polygons.
APIBody_Closed: its geometry is closed.
APIBody_Curved: it has smooth polygons.
