摘要
针对传统的公路工程建模需要大量人机交互操作,建模过程复杂和成本高的问题,提出一种参数化建立公路工程模型的方法。首先,应用SketchUp结合GIS地理信息建立环境模型;然后通过对公路竣工图纸的分析精确定位公路工程坐标,依据坐标定位公路沿线所在位置;通过Profile Builder对公路基层、面层、护栏等元素参数化,根据竣工图纸在Profile Builder中参数化建立公路模型。
Aiming at the problem that traditional highway engineering modeling requires a lot of human-computer interaction,the process of modeling is complex and the cost is high,a parametric method of building highway engineering model is proposed. Firstly, SketchUp is used to build the environment model based on GIS geographic information;secondly,the highway engineering coordinates are accurately positioned by analyzing the road completion drawings,and the location along the highway is positioned according to the coordinates;secondly,the highway model is established by parameterizing the elements of highway base,surface and guardrail through Profile Builder,and by parameterizing the completed drawings in Profile Builder.
