牆尺寸

Question

我想將元素之間的距離設置為某個值，以便尺寸清晰可見。 請在屏幕截圖下方找到。

目前看起來像這樣。

但我想實現如下。

Answer 1

創建尺寸時，實際上可以控制線。 從Revit中提取一條線，然后對其進行變換並使其垂直於您感興趣的線偏移：（給出dbView，一個參考數組和一條曲線）

//create your line along the element you want to dimension
Line line = Line.CreateBound(locCurve.Curve.GetEndPoint(0), locCurve.Curve.GetEndPoint(1));

//Compute the perpendicular of that line (I took advantage of the fact that I was working in plan:
XYZ perpendicular = line.ComputeDerivatives(0.5, true).BasisX.CrossProduct(new XYZ(0, 0, 1));

//transform the line to the new offset location:
Line offsetline = line.CreateTransformed(Transform.CreateTranslation(perpendicular.Normalize())) as Line;

//Create the dimension.
revitDoc.Create.NewDimension(dbView, offsetline, aDimensionRefArray);
