revit-api - 墙壁尺寸标注

Question

我想将元素之间的间隙设置为某个值，以便尺寸清晰可见。请在屏幕截图下方找到。

目前它看起来像这样。

但我想实现如下。

Answer 1

创建尺寸时，您实际上是在控制线。从 Revit 中取一条线，然后对其进行变换并将其垂直于您感兴趣的线偏移：（给定一个 dbView 和一个参考数组和一条曲线）

//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);
