revit api创建自定义线样式

线型在Revit里有LinePatternElement类来表示。 

        private LinePatternElement CreateLinePatternElement(string patternName){//Create list of segments which define the line patternList<LinePatternSegment> lstSegments = new List<LinePatternSegment>();lstSegments.Add(new LinePatternSegment(LinePatternSegmentType.Dot, 0.0));lstSegments.Add(new LinePatternSegment(LinePatternSegmentType.Space, 0.02));lstSegments.Add(new LinePatternSegment(LinePatternSegmentType.Dash, 0.03));lstSegments.Add(new LinePatternSegment(LinePatternSegmentType.Space, 0.02));LinePattern linePattern = new LinePattern(patternName);linePattern.SetSegments(lstSegments);Transaction trans = new Transaction(doc);trans.Start("Create a linepattern element");LinePatternElement linePatternElement = LinePatternElement.Create(doc, linePattern);trans.Commit();return linePatternElement;}

创建线型之后，可以把这个线型赋值给线样式。这里把一个线样式列表中的对象都进行修改线型。

 LinePatternElement myLinePatternElement = CreateLinePatternElement("MyLinePattern");foreach (ElementId typeId in lstGridTypeIds){Element gridType = doc.GetElement(typeId);//set the parameter value of End Segment PatternSetParameter("End Segment Pattern", myLinePatternElement.Id, gridType);}
