overview 概述
Creates an extruded feature. This function behaves like UF_MODL_create_extrusion, except that the extruded direction is determined by the direction of the input datum. The resulting body is a solid if the input string is closed and the solid_creation option is TRUE. Otherwise a sheet body results. A sheet can not be tapered and the taper_angle must be set to 0.0. The UF_MODL_SWEEP_TRIM_object structure is used to define the trim objects. The trim_options is used to define the trim options if the UF_MODL_SWEEP_TRIM_object structure is specified.
The limits of extrusion are valid only if the UF_MODL_SWEEP_TRIM_object structure is not specified (NULL). The region point corresponds to the point chosen after selecting intersecting objects. If the region_point_specified is false then the region point is ignored.
创建一个挤压特性。这个函数的行为类似于 UF _ MODL _ create _ 挤压，只不过挤压的方向是由输入数据的方向决定的。如果输入字符串是关闭的，并且 Solid _ create 选项为 TRUE，则生成的主体为实体。否则将产生工作表主体。纸张不能变细，而且锥度 _ 角必须设置为0.0。UF _ MODL _ SWEEP _ TRIM _ object 结构用于定义修剪对象。如果指定了 UF _ MODL _ SWEEP _ TRIM _ object 结构，则使用 trim _ options 定义 trim 选项。只有在未指定 UF _ MODL _ SWEEP _ TRIM _ object 结构(NULL)的情况下，挤压限制才有效。区域点对应于选择相交对象后所选择的点。如果 region _ point _ spected 为 false，则忽略该区域点。

parameters 参数
| tag_t * | extrude_array | Input | List of objects to be extruded. 要挤压的对象列表。 |
| int | extrude_count | Input | Count of the objects to be extruded. 要挤压的物体的数量。 |
| UF_MODL_SWEEP_TRIM_object_p_t | trim_ptr | Input | The structure that contains the trimming data. 包含裁剪数据的结构。 |
| UF_MODL_SWEEP_TRIM_OPTS | trim_options | Input | Trimming options: DO_NOT_EXTEND_TRIM_FACE = do not extend the trimming face, DO_NOT_EXTEND_AND_EXTEND_TRIM_FACE = first do not extend the trimming face and perform boolean operation. If fails, extend the trimming face and perform boolean. EXTEND_FIRST_TRIM_FACE = extend the first trimming face, EXTEND_SECOND_TRIM_FACE = extend the second trimming face, EXTEND_BOTH_TRIM_FACES = extend both trimming faces 修剪选项: DO _ NOT _ EXTEND _ TRIM _ FACE = 不要扩展修剪面，DO _ NOT _ EXTEND _ AND _ EXTEND _ TRIM _ FACE = 首先不要扩展修剪面并执行布尔运算。如果失败，扩大修整面和执行布尔。EXTEND _ FIRST _ TRIM _ FACE = 延伸第一修边面，EXTEND _ SECOND _ TRIM _ FACE = 延伸第二修边面，EXTEND _ BOTH _ TRIM _ FACE = 延伸两个修边面 |
| char * | taper_angle | Input | The taper angle for the extrusion. 挤压用锥角。 |
| char * | limits [ 2 ] | Input | extrude_count The limits of the extrusion. Only used if the trim_ptr argument is NULL. 挤压的限制。只有在 trime _ ptr 参数为 NULL 时才使用。 |
| char * | offsets [ 2 ] | Input | The offsets for open strings 开放字符串的偏移量 |
| double | region_point [ 3 ] | Input | The point on the region desired. 所需区域上的点。 |
| logical | cut_specified | Input | TRUE or FALSE for region desired. 所需区域为真或假。 |
| logical | solid_body_creation | Input | If TRUE, create solid bodies if the input string is closed. Otherwise sheet bodies will be created. 如果为 TRUE，则在输入字符串关闭时创建实体，否则将创建工作表实体。 |
| tag_t | datum_eid | Input | Object identifier of a datum which will provide the direction of the extrusion. 数据的对象标识符，它将提供挤压的方向。 |
| UF_FEATURE_SIGN | sign | Input | The sign of the operation to be performed: UF_POSITIVE = add to target solid UF_NEGATIVE = subtract from target solid UF_UNSIGNED = intersect with target solid 要执行的操作符号: UF _ POSITIVE = 加入到目标固体 UF _ NEGATIVE = 减去目标固体 UF _ UNSIGNED = 与目标固体相交 |
| tag_t * * | objects | Output to UF_free | An array of extruded feature tags. This must be freed by calling UF_free. 一个挤压的特性标签的数组。这必须通过调用 UF _ free 来释放。 |
| int * | object_count | Output | The number of features returned in the objects array. 在对象数组中返回的特性数。 |
