Selecting Body (bodies) with Dynamo

Civil3D

1

Seeing this thread (Select all multi-leaders and delete) I’d like to share my approach on selecting (unknown) types in Dynamo. Now I found the “expose extra object types” node usefulle but still missed some types. This is my solution to this problem using the Civil3DToolkit. Hope you find it helpfull, comments are appreciated as well.

                btrID = bt.get_Item("*Model_Space")
                mspace = t.GetObject(btrID, OpenMode.ForRead)

                        if type(obj) == Body:
                            dobj = DA.Object.InternalMakeObject(obj, False)
                            dynamo_objects.append(dobj)
                    except:

                pass
        except:
            pass

# Assign your output to the OUT variable.
OUT = dynamo_objects
