删除实体及其所有集合数据的正确方法是什么?

What is the correct way to remove an entity and all of its collection data?

在 Eyeshot 中,从属于 BlockReferenceModel 中删除 Entity 的最佳方法是什么?
是否有方法可以帮助清理基于 BlockReference 的所有 Blocks

// assume "model1" is the Eyeshot control 

List<Entity> entities = GetEntitiesToRemove();
foreach (var entity in entities)
{
   if (entity is BlockReference reference)
   {
       // What to do here to clean up the associated blocks?  This code will only find the
       // parent block for the entity
       var block = model1.Blocks.FirstOrDefault(b => b.Name == reference.BlockName);
       if (block != null)
       {
           model1.Blocks.Remove(block);  //This is only removing the parent block 
       }
   }
   model1.Entities.Remove(entity);
}

Model.Purge() 方法:从 Environment 主集合(层、块、材质等)中删除未使用的项目
