Getting all the Entities of a Particular Layer

[nthangaraj]

How to get all the Entities in a Particular Layer.
Can we filter the Entities selected using MultipleSelect with respect to Layers?

[nthangaraj]

Also can we Get only the Selected type of Entities from the Selected Enities.
(Say Only Polyline or Rotated Entities)

Hello,
To get all entities in one certain layer, use the following code:

Code: Select all

public List<CADEntity> GetAllLayerEntities(CADImage img, string layerName)
        {
            List<CADEntity> ResList = new List<CADEntity>();
            for (int i = 0; i < img.Converter.Entities.Count; i++)
            {
                CADEntity ent = img.Converter.Entities[i];
                if (ent.Layer.Name == layerName)
                {
                    ResList.Add(ent);
                }
            }
            return ResList;
        }

Also, it is possible to filter entities selected by MultipleSelect according to layers:

Code: Select all

 public List<CADEntity> GetSelectedByLayer(CADImage img, string layerName)
        {
            List<CADEntity> ResList = new List<CADEntity>();
            for (int i = 0; i < img.SelectedEntities.Count; i++)
            {
                CADEntity ent = img.SelectedEntities[i];
                if (ent.Layer.Name == layerName)
                {
                    ResList.Add(ent);
                }
            }
            return ResList;
        }

This is how you can get only the selected type of entities from the selected entities:

Code: Select all

 public List<CADEntity> GetSelectedByType(CADImage img,EntityType type)
        {
            List<CADEntity> ResList = new List<CADEntity>();
            for (int i = 0; i < img.SelectedEntities.Count; i++)
            {
                CADEntity ent = img.SelectedEntities[i];
                if (ent.EntType==type)
                {
                    ResList.Add(ent);
                }
            }
            return ResList;
        }
