如何在revit中找到斜坡的开始/结束，也许是草图? [英] How to find start/end of ramp in revit, perhaps with sketches?

问题描述

我有一堆斜坡，我想知道它们的起点和终点(如果有多个起点/终点，我想知道它们是如何连接的).我目前将这些作为

I have a bunch of ramps that I would like to know the begin and end points of (and in case of multiple begin/end points I would like to know how they connect). I currently get these as

List<TransitionPoint> ret = new List<TransitionPoint>();
FilteredElementCollector collector = new FilteredElementCollector(doc);
ICollection<Element> ramps = collector.OfCategory(BuiltInCategory.OST_Ramps).ToElements();

foreach (var ramp in ramps)
{
   //what goes here?
}

这些斜坡包含以下属性:

These ramps contain the following properties:

Type Comments
Ramp Max Slope (1/x)
Category

Type Name
Ramp Material
Function
Manufacturer
Family Name
Model

现在，如果这些楼梯我会使用 ICollection stairs = collector.OfCategory(BuiltInCategory.OST_Stairs).OfClass(typeof(Stairs)).ToElements();然后我可以将对象转换为 Stairs 但是似乎没有一个类 simmulair to Stairs 这将允许我处理 Stairs.GetStairsRuns().

Now if these where stairs I would use ICollection stairs = collector.OfCategory(BuiltInCategory.OST_Stairs).OfClass(typeof(Stairs)).ToElements(); and then I can cast the objects into Stairs however there does not appear to be a class simmulair to Stairs which would allow me to adres Stairs.GetStairsRuns().

有人知道如何获得 RampRun 之类的东西或以其他方式找到坡道的起点和终点吗?

Anybody know how to either get something like a RampRun or otherwise find the start and end of a ramp?

我也尝试了以下解决方案，但也没有用

I have also tried the following sollution but that didn't work either

public static void MapRunsToRamps(Document doc)
{
   var rule = ParameterFilterRuleFactory.CreateNotEqualsRule(new ElementId(BuiltInParameter.HOST_ID_PARAM), "null", true);

   ElementParameterFilter filter = new ElementParameterFilter(rule);
   FilteredElementCollector collector = new FilteredElementCollector(doc);
   List<Element> rampsRuns = collector.WherePasses(filter).ToElements().ToList<Element>();
   foreach (Element e in rampsRuns)
   {
      var hostpara = e.get_Parameter(BuiltInParameter.HOST_ID_PARAM);
      if (hostpara != null)
      {
         var host = doc.GetElement(new ElementId(hostpara.AsInteger()));
         if (host.Category.Equals(BuiltInCategory.OST_Ramps))
         {
            //breakpoint that is never activated 
         }
      }
   }
}

这会发现很多物体都没有斜坡作为宿主.

This finds plenty of objects just none with a ramp as a host.

这是一个坡道示例，我试图找到用红色箭头标记的位置.

Here is an example of a ramp and the location I'm trying to find marked with red arrows.

这个 https://forums.autodesk.com/t5/revit-api/how-do-we-get-the-xyz-cordinates-for-stairs-ramps/td-p/2575349 建议我们可以使用位置曲线，有什么办法吗?

this https://forums.autodesk.com/t5/revit-api/how-do-we-get-the-x-y-z-cordinates-for-stairs-ramps/td-p/2575349 suggests that we can use a locationcurve, any way to do that?

似乎确实有草图，我们可以根据这些草图找到坡道，问题是我是否有草图说

edit: There do appear to be sketches based on which we might be able to find the ramps, question is if I have a sketch say with

    var rampCategoryfilter = new ElementCategoryFilter(BuiltInCategory.OST_StairsSketchRunLines);
    var rampsRuns = new FilteredElementCollector(doc).WherePasses(rampCategoryfilter);

那么我确实可以找到位置，但我没有的是它也属于的坡道，知道如何找到它吗?

then I can indeed get the locations but what I do not have is the ramp that this belongs too, any idea how to find that?

推荐答案

假设你的 Ramp 是一个 FamilyInstance :

Assuming that your Ramp is a FamilyInstance :

var fecRamps = new FilteredElementCollector(doc)
    .OfClass(typeof(FamilyInstance))
    .Where(pElt =>
    {
        int lCatId = pElt.Category.Id.IntegerValue;
        return lCatId == (int)BuiltInCategory.OST_Ramps;
    })
    .OfType<FamilyInstance>()
    .ToList();

List<XYZ> lRampLocs = new List<XYZ>();
foreach (var pFam in fecRamps)
{
    var fLoc = pFam.Location as LocationCurve;
    var fRampSide1 = new XYZ(fLoc.Curve.GetEndPoint(0);
    var fRampSide2 = new XYZ(fLoc.Curve.GetEndPoint(1);

    lRampLocs.Add(fRampSide1);
    lRampLocs.Add(fRampSide2);
}

每个FamilyInstance 都有一个Location，您可以将Location 转换为LocationCurve.从曲线中，您可以通过 Autodesk.Revit.DB 命名空间获得端点.

Every FamilyInstance has a Location and you can cast the Location as a LocationCurve. From the curve, you can get the end points via the Autodesk.Revit.DB namespace.
