射线法求交是很多三维模型求碰撞和测量间距最常用的节点，但是再使用射线法将target设置为element的时候会发现会出现两个相同的值。下面用楼板距离，下图中会出现两个不同的值，在我修改板厚之后发现正好是板厚的距离，可以猜测射线法会对两个face进行判定相交，但是与我们需要的每个element输出一个值不符，这里需要重新做一次判定或者直接取最小值获得净高。 123456789101112131415161718var intersector = new ReferenceIntersector(classFilter, FindReferenceTarget.Element, modelView); intersector.FindReferencesInRevitLinks = true; var result = intersector.Find(origin, -XYZ.BasisZ); foreach (var context in result) &#...

Ray intersection is one of the most commonly used nodes for collision calculation and distance measurement in many 3D models. However, when using the ray method and setting target to element, you will find that two identical values appear.Using floor distance as an example, two different values appear in the figure below. After I modified the slab thickness, I found that it was exactly the distance of the slab thickness. It can be guessed that the ray method determines intersection for both f...

After Revit 2018, the method for obtaining Grid Reference has been modified. You need to use the following code to retrieve it: 12345foreach (Grid grid in grids) { var reference = new Reference(grid); gridReferences.Append(reference); } Previously, you needed to get the Grid’s Curve.Reference to create dimensions: 1gridReferences.Append(grid.Curve.Reference); The change should be made to obtain Grid References more safely and convenie...

在Revit2018以后，修改了Grid的Reference获取办法，需要使用下面的代码进行获取 12345foreach (Grid grid in grids) { var reference = new Reference(grid); gridReferences.Append(reference); } 而在之前是需要获取Grid的Curve.Reference才能进行标注创建 1gridReferences.Append(grid.Curve.Reference); 改动应该是为了更加安全便捷的获取Grid的Refence而做出的修改。关于这个事情的官方回答详情可以看下面这篇文章Invalid Number of References

The company plugin’s beam-to-slab function has been updated. The designer requested a feature to split arc beams and align them to the top of the slab. This article only discusses splitting arc beams; ellipses will be updated later. First, let’s look at the arc creation APIThe API provides three methods:The first one is specifying the start point and end point, and finally selecting a point on the arc.The second one is specifying the plane, radius, start angle, and end angle.The third one is...

公司插件的梁齐斜板功能更新，设计师提出需求可以拆分弧梁，并能对齐到板顶。 本文只讨论拆分弧梁，椭圆再后续更新。 首先看以下弧形的创建apiAPI中提供了三种方法第一种时指定起点与终点，最后选择顶点形成的弧形第二种是指定面，半径，起点角度与终点角度第三种则是弧形中心点，半径，起点角度，终点角度，x向量，y向量 拆分弧形，意思就是如果遇到板边界需要拆分，需要将此弧形按照板边界划分成两个弧形，第一种办法肯定无法实现，后两种的化就需要了解什么是起点角度与终点角度，并如何计算 下面是我的理解，后面彻底完成后再继续补充，可能有些混乱，怕后面忘记(所有的弧形是逆时针旋转) 弧形内部有三个参数(xDir,yDir,normal),这三个参数代表横向向量，纵向向量，和法向量 下面是两个相反的值比较，可以发现法向量在俩面决定了整个弧形方向，此处可以使用右手法则理解 也就是说，此处如果按照常规布置，我们可以求startangle和endangle，公式如下所示： 12var dir0 = (arc.GetEndPoint(0) - arc.Center).Normalize(); ...

Developing a family library plugin involves many interactive commands and requires many bindings. Using MVVM to directly bind Commands makes the entire ViewModel too messy. Here, an ICommandManage interface is created to manage Commands. The ValueConvert interface in WPF is used to convert the passed string into an ICommand command.

I made a plugin to automatically calculate the clear height, which requires marking the height with annotation blocks, but boundary lines appeared when it came out, as shown below. Defining width through filledregionType’s lineweight failed, and setting through LineStyleId also failed because directly obtaining LineStyle style only gets lines in Manage -> Line Styles, not the category we need.Here we need to collect GraphStyle to find the invisible line Id and assign it directly.

做了一个自动测算净高的插件，需要通过注释块标记高度，但是出来的时候会有边界线，如下图，通过filledregionType的lineweight定义宽度失败，通过LineStyleId进行设置，但是直接获取LineStyle样式只会获取管理->线样式里面的线，没有我们需要的<不可见线>这个分类。此处需要收集以下GraphStyle找到不可见线Id直接赋值即可,实例中我将绿色的部分进行边界取消 123456789var filter = new FilteredElementCollector(doc); var dates = filter.OfClass(typeof(GraphicsStyle)).ToElements(); var line = dates.Where(x => x.Name.Contains("线")).ToList(); var fake = line.FirstOrDefault(x => x.Name.Contains("不...
