在運用的時候,會遇到想找收集相連結的牆,用API提供的方法的話,總是會出錯。會漏掉一些自己需要的牆,因此,下面封裝了一個可以計算牆的是否連線的方法,先上程式碼後講解Just Do It!!!
public bool IsConnected(Wall judgeWall, Wall proWall)
{
bool result = false;
Line judgeLocationLine = ((judgeWall.Location as LocationCurve).Curve as Line).SetZ();
Line proLocationLine = ((proWall.Location as LocationCurve).Curve as Line).SetZ();
//只對平行的處理
if (!judgeLocationLine.Direction.IsParallel(proLocationLine.Direction)) return result;
var judgeGeo = judgeWall.get_Geometry(new Options());
Face jugeDownFace = GeoEx.GetGeoEleDownFace(judgeGeo);
var proGeo = proWall.get_Geometry(new Options());
Face proDownFace = GeoEx.GetGeoEleDownFace(proGeo);
List<Solid> solidList = new List<Solid>();
//收集幾何體
double judgeSolidSurfaceArea = 0;
double prosolidSurfaceArea = 0;
List<Solid> judgeSolids = GeoEx.GetSolids(judgeGeo);
List<Solid> proSolids = GeoEx.GetSolids(proGeo);
foreach (var judgeSolid in judgeSolids)
{
judgeSolidSurfaceArea += judgeSolid.SurfaceArea;
solidList.Add(judgeSolid);
}
foreach (var proSolid in proSolids)
{
prosolidSurfaceArea += proSolid.SurfaceArea;
solidList.Add(proSolid);
}
Solid fuseSolid = SolidBatchBoolean(solidList,BooleanOperationsType.Union);
if (judgeSolidSurfaceArea + prosolidSurfaceArea - fuseSolid.SurfaceArea > 0)
{
result = true;
}
return result;
}
public Solid SolidBatchBoolean(List<Solid> solids, BooleanOperationsType booleanOperationsType)
{
Solid firstSolid = solids[0];
solids.RemoveAt(0);
//對所有的幾何體進行融合
foreach (var oneSoild in solids)
{
try
{
firstSolid = GeoEx.SolidBooleanOperation(firstSolid, oneSoild, booleanOperationsType);
}
catch
{
}
}
return firstSolid;
}
案例中是隻對當前狀況下
思路:
取兩個牆的Solid,進行布林運算的並集運算,然後計算新的solid的表面積,最後對錶面積進行數值上的比較。如果表面積大於兩個solid的話說明是相連線的。
