本文介绍如何使用procedureCreateShape函数创建指定类型的3D形状，并在指定的层上激活编辑操作。此过程适用于支持特定维度类型的层。了解如何通过提供起点坐标、形状类型和维度类型参数来创建和编辑3D形状。

procedure CreateShape(const _layer: TObject; const _ptg: TGIS_Point3D; const _type: TGIS_ShapeType; const _dim: TGIS_DimensionType);

Parameters	Description
const _layer: TObject	TGIS_Layer which will own new shape
const _ptg: TGIS_Point3D	"starting" 3D of a new shape to be created; expected Viewer coordinate system
const _type: TGIS_ShapeType	type of shape to be created; it must be type supported by layer; if gisShapeTypeUnknown then shape of default type will be created
const _dim: TGIS_DimensionType	dimension of shape to be created; it must be type supported by layer; if gisShapeTypeUnknown then shape of default dimension will be created
