笔者是一名大三的土木工程专业的学生,自学编程一年半,今年寒假找了一份做CAD插件的实习,实习中第二个项目就是几乎是自己独立完成的项目.虽然项目不大,但是还是收获良多.
暖通接天正
项目背景
这是一个CAD设计图的一部分,这个图有点不清晰,我们找到其中一个代表图
先要用netload导入dll文件,然后输入THFPM即可调用生成风口和风阀程序
注意到右下角的是否生成天正构件的选框,这个选框原本是没有的,笔者后来在UI上面添加了,这里我们先不勾选进行操作
- 选中风机(风机具有不同的类型)不同的类型的生成逻辑还不一样
- 调整不同类型的风口
- 进行生成
这些构件是平面图形,而且位置是不对的,应该生成在风管里面才对
这里生成的构件是CAD构件,只是一个平面图形,实际上在生产应用中,设计图要是立体的才行,而且要可以有其他属性,所以我们引入了天正构件
我们对于选框进行勾选,从而生成天正构件,下面是效果图
代码逻辑
UI界面的设计
红色的选框是我添加的,使用了winform工具来生成UI,winform我用的并不熟悉,但是还是勉强可以做的.
然后在winform的代码中添加checkbox
private System.Windows.Forms.CheckBox chk_generate_TCH;
这里有很多的UI的变量
这些变量都是要被初始化的
记录UI的值实际上用到了单例设计模式
public ThHvacFpmCmd()
{
ActionName = "风平面";
CommandName = "THFPM";
cmdService = new ThHvacCmdService();
if (singleInstance == null)
{
singleInstance = new PortParam();
singleInstance.param = new ThMEPHVACParam(); ;
}
}
插入天正构件的逻辑
插入天正构件的逻辑其实并不算太复杂,但是对于当时的我还是有一定挑战的,简单的来说就是要构造出一个天正构件的对象,这个对象有充足的数据,将这些数据插入到和天正建筑软件链接的数据库,就可以实现插入天正构件
插入天正风口 这段代码的的业务逻辑也不算简单,依据生成的风管,读取风管的数据,还要读取要生成的风口的数据,而且最困难的是对于不同情况,数据要做不同的处理,其中还包含了一些几何变换等等,

风口表的对应关系
分别是三张表
- DuctAirLets
- DwbBlocks
- Materials 这三张表的数据是相互关联的,因为产品经理也不知道,经过很多核对,终于发现要插入的是这三张表,当时给我带来了很大困扰
插入风阀
插入风阀总体来说和插入风口的逻辑相似,但是它的难点在于天正阀门和CAD阀门的定位点是不一样的,所以插入位置会有很大偏差,不仅如此,各个阀门的方向还不一样,这就给获取合适的定位点带来了挑战,这里我的解决方式是构造两个互相垂直的向量,在两个互相垂直的向量上移动相应的距离,从而获取正确的位置

这里在生成阀门的时候要分成两种情况
生成阀门需要的数据库表
是否消防加压送风也要分成两种情况

这里面最令人头痛的莫过于要额外插入电动阀门,这个插入电动阀门的的位置是很难获取的,因为它和上面获取位置的逻辑又不太一样,而且电动阀门的长宽也要重新寻找
插入两种电动阀门的寻找位置的逻辑完全不同,产品经理也没给我具体的方法,只能硬着头皮去前任程序员写的代码一点点去找线索.
改BUG
前任程序员在生成CAD构件的时候出现了一个bug,就是生成构件的标高居然是负的,而且负的没有规律,然后我也按照他的逻辑去生成构件,结果产品经理告诉我是错的,那没办法,只能我一个实习生去给他擦屁股了. 费了我一个下午的时间,终于把问题找到了,原来是前任程序员在进行位置变换的时候出现了一个低级的错误,我在他的基础上把错误进行修正,但是要修改的地方实在是很多,费了我很多精力,终于算是解决了.
public void DrawVTDuct(List<SegInfo> segInfos, Matrix3d mat, bool isTextSide, ThMEPHVACParam param, ref ulong gId)
{
var gap = ThTCHCommonTables.flgThickness * 0.5;
foreach (var seg in segInfos)
{
var l = seg.GetShrinkedLine();
l.StartPoint = new Point3d(l.StartPoint.X, l.StartPoint.Y, l.StartPoint.Z - mat.CoordinateSystem3d.Origin.Z);
l.EndPoint = new Point3d(l.EndPoint.X, l.EndPoint.Y, l.EndPoint.Z - mat.CoordinateSystem3d.Origin.Z);
//改bug的地方
if (l.Length < lineLimition)
continue;
RecordDuctInfo(seg.airVolume, ref gId);
RecordDuctDimContents(ref gId);
RecordDuctDimensions(mat, seg, param, isTextSide, ref gId);
GetWidthAndHeight(seg.ductSize, out double width, out double height);
var dirVec = (l.EndPoint - l.StartPoint).GetNormal();
var sEndParam = new TCHInterfaceParam()
{
ID = ductParam.startFaceID,
sectionType = ductParam.sectionType,
height = height,
width = width,
normalVector = dirVec,
heighVector = new Vector3d(0, 0, 1),
centerPoint = (l.StartPoint.TransformBy(mat) + (gap * dirVec)),
};
var eEndParam = new TCHInterfaceParam()
{
ID = ductParam.endFaceID,
sectionType = ductParam.sectionType,
height = height,
width = width,
normalVector = -dirVec,
heighVector = new Vector3d(0, 0, 1),
centerPoint = (l.EndPoint.TransformBy(mat) - (gap * dirVec))
};
ThTCHService.RecordPortInfo(sqliteHelper, new List<TCHInterfaceParam>() { sEndParam, eEndParam });
}
sqliteHelper.CloseConnect();
}
整个项目做完还是很有收获的,掌握了很多调试技巧,提升了很多分析代码和写代码的能力,转码路漫漫,感觉做什么都不容易,继续加油吧.
