集成交互式道路与立交设计系统—EICAD用户手册 纵断面设计部分 第79页
第四篇 纵断面设计部分使用说明
本软件采用C++语言开发，具备了很强的功能，能完成各种道路（包括立交）的路线纵断面设计，并完成初步设计和施工图设计阶段的路线纵断面图和竖曲线设计表。
软件运行环境为Windows 9X 及以上版本和AutoCAD R14.0/2K/2K2/2K4/2K5/2K6图形软件包。硬件要求为Pentium 166MHz以上，内存128M以上。 本软件具有以下显著特点：
1、采用动态交互方式完成设计。用户通过鼠标点取的修改对象（变坡点、坡度线、竖曲线等），随着鼠标的移动，屏幕上动态地显示路线修改方案和相应的设计参数（桩号、高程、坡度、坡长、竖曲线半径、切线长、外距等）的变化，通过拖动步长（桩号步长、坡度步长）、拖动比例和拖动方式（人工指定变坡点桩号、高程、前坡、后坡等十余种方式）的调整，可以在毫米级的精度上，使设计很快达到用户的要求，从而大大地提高设计效率。
2、具有强大的管理能力。用户能够在同一个图形文件中，在同一时间内随意地在进行任意多条道路的纵断面设计。软件的这一强大管理功能，对于立交设计或同一条道路多个设计方案的比较，是极其有利的。不论这些道路有无桩号断链，软件都能灵活地加以识别和处理。每条道路的桩号断链数可多达100个，纵断面的变坡点数可多达1000个，地面线中桩数可多达10000个，足以满足用户的各种需要。
3、灵活的高程控制功能。用户在设计时可采用动态交互方式插入、移动和删除高程控制点，修改设计时，屏幕上可动态显示各高程控制点处设计高程与控制高程的高差，从而使设计极易达到控制高程的要求。每条道路的高程控制点数可多达1000个。
4、方便的参数化设计功能。为适应用户的不同需要，本软件具备了完善的参数化设计功能，例如，对于变坡点的位置，可以通过键盘输入桩号、高程、前坡度、后坡度四个要素中的任意两项得到，极大地方便了设计者。
5、友好的用户界面。软件采用汉化界面，所有数据的输入等人机对话均在对话框中进行。这些对话框随时检查输入数据的合法性和合理性，并有完善的出错提示功能和帮助功能。在动态交互设计过程中，软件随时检查修改设计方案的合理性，如果出现相邻竖曲线“穿袖”或变坡角为零时，将自动舍去不合理的方案，并通过报警，动态地提示信息。对所有变坡点和控制点，软件均在屏幕上给予编号，当用户插入、移动和删除上述点时，这些编号会自动按顺序进行调整，使用户感到非常直观。在动态交互设计过程中，程序随时提供在线帮助服务。
6、强大的修改设计功能。修改后的设计可以图形文件的形式保存，以后再修改时，可直接将图形文件调入，不必每次用数据文件来绘制图形，给用户带来很大方便。当用户对自己所作的修改设计不满意时，可非常方便地逐步撤消前一次修改，可撤消修改的步数不受限制，直到撤消完每一步修改设计后为止。
7、丰富的设计查询功能。用户可在屏幕上随时查询任一条道路的信息，如查询设计线要素、查询控制点，查询桩号断链、进行技术指标分析，估算土石方数量，绘土石方累计曲线等。此外，软件还具有动态查询指定道路的功能，即随鼠标的移动，屏幕上动态地显示桩号、设计高程、地面高程、填挖高度、坡度、坡长、竖曲线半径、切线长、累计填方和累计挖方等各种技术参数。
8、适应性极强的设计图表绘制功能。用户可在对话框中极其方便地任意定义设计图表的格式，例如，路线纵断面图图框大小，图内标注栏的栏数，各标注栏的内容、顺序和标注精度，标注栏的高度和字体大小、宽度系数、倾斜角度、网格线水平和垂直间距、断链间距等绘图内容的选择，并可以把这些定义用工作文件的形式保存起来便于日后应用。总之，软件把可供选择的方式尽可能地在对话框中列出，以最大限度地满足不同用户的需要。
