Topic: How to Collect / Explode AECC objects?

[nobody]

I want to explode all civil 3d objects in a drawing with the API...is there an efficient way to do this without iterating through every entity and checking for "AEC" then exploding them individually? Or at least a way to limit the data I check?

Get a selection set using {0, "AECC-*"} for the filter?

yea :/ was hoping there was a secret aecc.explodeeverything method I didn't know about lol

In my opinion iteration is not a problem... For example, iteration of 736 323 objects of database (DWG size is more than 50 Mb)  takes a 00:00:00,2781968 (i.e. less than one second).

Code - C#: [Select]

1. public static ObjectId[] GetDBObjectIds(this Database db,
2.         Func<ObjectId, Boolean> filter) {
3.  
4.         // Check arguments
5.         if (null == db)
6.                 throw new ArgumentNullException("null == db");
7.         if (null == filter)
8.                 throw new ArgumentNullException("null == filter");
9.         if (db.IsDisposed)
10.                 throw new ArgumentException("true == db.IsDisposed");
11.  
12.         // -------------------
13.         Int32 approxNum = db.ApproxNumObjects;
14.         List<ObjectId> ids = new List<ObjectId>();
15.  
16.         for (Int64 i = db.BlockTableId.Handle.Value; i < db.Handseed.Value
17.                 && approxNum > 0; ++i) {
18.  
19.                 Handle h = new Handle(i);
20.                 ObjectId id = ObjectId.Null;
21.  
22.                 Boolean parseResult = db.TryGetObjectId(h, out id);
23.  
24.                 if (parseResult) {
25.                         --approxNum;
26.                         if (filter(id)) {
27.                                 ids.Add(id);
28.                         }
29.                 }
30.         }
31.         return ids.ToArray();
32. }

I use it for the searching, exploding, and removing all proxy in the Database (usual AutoCAD).

But with exploding each AEC object one at a time?

I don't understand you. What do you mean?

eh...I was just hoping there was an allaecobjects.explodeinstantly() method available that I just didn't know about.

Exploding objects will create new AutoCAD objects, after that you need to erase the original objects.

Erasing objects will affect the existence of others, if you immediately erase an Alignment after exploding, all Profiles and Profile Views and Sections etc will be deleted too.

So you better explode all object first, then erase all original objects inside a try-catch.

Or, send a Command Line string: "Explode all".
