Title: Region meshing
Post by: Andrey Bushman on June 03, 2014, 04:31:35 PM

It is necessary to mesh the target regions. Each output "cell" must to be a region too. It is not difficult for common cases:

But sometime some output regions can to be consisting of several parts:

I need exclude such results. Each output region must to be as a single one. How can I to separate such regions to the certain regions?

Can I create the Region based on a Face object from the Brep.Faces collection?

If the Brep of the Region has more than one Complex, Explode the Region.  That should return a DBObjectCollection of Regions that were the individual pieces of the original.  Delete the original Region if necessary.

Thank you! Explode works fine! In my code I cheked the Faces instead of Complex.

Code - C#: [Select]

1. using(Br.Brep brep = new Br.Brep(rowClone)) {
2.   if(brep.Faces != null && brep.Faces.Count() > 1) {
3.     using(Db.DBObjectCollection explodeResult =
4.       new Db.DBObjectCollection()) {
5.       rowClone.Explode(explodeResult);
6.       foreach(Db.DBObject item in explodeResult) {
7.         result.Add((Db.Region)item);
8.       }
9.     }
10.  
11.     if(!rowClone.IsDisposed)
12.       rowClone.Dispose();
13.   }
14.   else
15.     result.Add(rowClone);
16. }

Can I get a problem this case?

For Regions that probably will work.
