以坐标和角度定位弧线轴网的方法——以Revit为平台的建模过程

Study on the Method of Locating Arc Grid by Coordinates and Angles:Revit Software as the Platform

已知弧线轴网的坐标点、角度和弧长,使用Revit建模软件建立弧线轴网时,用轴网的常规绘制方法是很难定位弧线轴网的。为此,以弧线轴网为研究对象,提出了一种模型线过渡建模方法,即用项目基点定位坐标点,借助软件中“模型线”的“起点-终点-半径弧”绘制弧线轴网草图,然后用软件中“轴网”的“起点-终点-半径弧”或者“拾取线”精确绘制弧线轴网。研究表明:采用模型线过渡建模方法可以精确地定位弧线轴网。

The coordinate point,angle and arc length of the arc grid are known,and the arc grid is established by Revit modeling software.In order to solve the above problems,this paper takes the arc grid as the research object,and proposes a modeling method,that is,the model line transition method,which locates the coordinate points with the project base point,draws the sketch of the arc axis network with the help of the"Start-End-Radius arc"in the"model line",and then uses the"Start-End-Radius arc"or the"pick lines"in the"Grid"to accurately draw the arc grid.The results show that the model line transition method can accurately locate the arc grid.
