Revit SDK：ViewFilters 视图过滤器

前言

这个例子用 API 重新对视图过滤器的功能的实现。

内容

原生视图过滤器和API实现版本对比：

核心逻辑

创建视图过滤规则的逻辑：

1. 通过ParameterFilterRuleFactory创建FilterRule，例如：PFRF.CreateBeginsWithRule(paramId, RuleValue, CaseSensitive)
2. 创建ElementParameterFilter： ElementParameterFilter elemParamFilter = new ElementParameterFilter(filterRule);
3. 创建ParameterFilterElement：ParameterFilterElement.Create(m_doc, myFilter.Key, categoryIdSet, elemFilter);

创建过滤规则，数值比较与字符串操作：ParameterFilterRuleFactory

namespace Autodesk.Revit.DB
{
    public class ParameterFilterRuleFactory : IDisposable
    {
        public static FilterRule CreateBeginsWithRule(ElementId parameter, string value, bool caseSensitive);
        public static FilterRule CreateContainsRule(ElementId parameter, string value, bool caseSensitive);
        public static FilterRule CreateEndsWithRule(ElementId parameter, string value, bool caseSensitive);
        public static FilterRule CreateEqualsRule(ElementId parameter, ElementId value);
        public static FilterRule CreateEqualsRule(ElementId parameter, int value);
        public static FilterRule CreateEqualsRule(ElementId parameter, double value, double epsilon);
        public static FilterRule CreateEqualsRule(ElementId parameter, string value, bool caseSensitive);
        public static FilterRule CreateGreaterOrEqualRule(ElementId parameter, string value, bool caseSensitive);
        public static FilterRule CreateGreaterOrEqualRule(ElementId parameter, double value, double epsilon);
        public static FilterRule CreateGreaterOrEqualRule(ElementId parameter, int value);
        public static FilterRule CreateGreaterOrEqualRule(ElementId parameter, ElementId value);
        public static FilterRule CreateGreaterRule(ElementId parameter, double value, double epsilon);
        public static FilterRule CreateGreaterRule(ElementId parameter, int value);
        public static FilterRule CreateGreaterRule(ElementId parameter, ElementId value);
        public static FilterRule CreateGreaterRule(ElementId parameter, string value, bool caseSensitive);
        public static FilterRule CreateHasNoValueParameterRule(ElementId parameter);
        public static FilterRule CreateHasValueParameterRule(ElementId parameter);
        public static FilterRule CreateIsAssociatedWithGlobalParameterRule(ElementId parameter, ElementId value);
        public static FilterRule CreateIsNotAssociatedWithGlobalParameterRule(ElementId parameter, ElementId value);
        public static FilterRule CreateLessOrEqualRule(ElementId parameter, int value);
        public static FilterRule CreateLessOrEqualRule(ElementId parameter, string value, bool caseSensitive);
        public static FilterRule CreateLessOrEqualRule(ElementId parameter, ElementId value);
        public static FilterRule CreateLessOrEqualRule(ElementId parameter, double value, double epsilon);
        public static FilterRule CreateLessRule(ElementId parameter, int value);
        public static FilterRule CreateLessRule(ElementId parameter, double value, double epsilon);
        public static FilterRule CreateLessRule(ElementId parameter, ElementId value);
        public static FilterRule CreateLessRule(ElementId parameter, string value, bool caseSensitive);
        public static FilterRule CreateNotBeginsWithRule(ElementId parameter, string value, bool caseSensitive);
        public static FilterRule CreateNotContainsRule(ElementId parameter, string value, bool caseSensitive);
        public static FilterRule CreateNotEndsWithRule(ElementId parameter, string value, bool caseSensitive);
        public static FilterRule CreateNotEqualsRule(ElementId parameter, string value, bool caseSensitive);
        public static FilterRule CreateNotEqualsRule(ElementId parameter, double value, double epsilon);
        public static FilterRule CreateNotEqualsRule(ElementId parameter, int value);
        public static FilterRule CreateNotEqualsRule(ElementId parameter, ElementId value);
        public static FilterRule CreateSharedParameterApplicableRule(string parameterName);
    }
}

对多个过滤规则进行组合：ElementFilter elemFilter = FiltersUtil.CreateElementFilterFromFilterRules(rules);

IList<ElementFilter> elemFilters = new List<ElementFilter>();
foreach (FilterRule filterRule in filterRules){
   ElementParameterFilter elemParamFilter = new ElementParameterFilter(filterRule);
   elemFilters.Add(elemParamFilter);
}
LogicalAndFilter elemFilter = new LogicalAndFilter(elemFilters);

创建过滤器：

ElementFilter elemFilter = FiltersUtil.CreateElementFilterFromFilterRules(rules);
IList<ElementId> categoryIdList = myFilter.Value.GetCategoryIds();
ISet<ElementId> categoryIdSet = new HashSet<ElementId>(categoryIdList);
ParameterFilterElement.Create(m_doc, "过滤器名称1", categoryIdSet, elemFilter);
