# DEMO示例
# 服务场景描述
应用IQCAD图纸解析引擎，通过调用API，可提取图纸中图框坐标，楼层，构件，图纸样式等图纸属性信息，并可对板文本内容进行知识抽取，识别实体以及实体关系。
可以通过接口调用实现以下场景
- 对图纸中的图框进行识别并获取图框中的图名，图号等信息
- 获取图框对应图纸的楼层，和构件分类
- 获取图纸中的楼层表
- 对板筋文本进行实体及实体关系抽取
接口调用流程
# 服务调用流程
# 1.服务调用前置条件
创建应用，获取appkey、appsecert；
获取服务调用token；
开通服务，scope授权通过；
以上步骤可参考前置准备
# 2.具体调用步骤
- 数据准备
上传dwg数据完成文件转换
step1： 上传dwg
可参考上传dwgAPI
step2： 获取文件状态
可参考获取文件状态API
step3： 发起转换
可参考图纸转换API
step4： 获取转换状态
可参考获取转换状态API
- 图纸特征结构化服务
调用服务进行图纸分割图签提取（SheetFrame）
调用服务提取楼层表信息（FloorTable）
step1： 图纸特征结构化服务
可参考图纸特征结构化服务API
step2： 获取图纸特征结构化状态
step3： 获取图纸特征结构化
