Can't save boolean operation to disk.

Anonymous — Fri, 26 Apr 2019 15:32:56 GMT

Hi,

In the following routine, while cycling through all the entities, i delete some of them and i do a boolean operation for some of them.

At the end I save the drawing with a new name. When I open the drawing, the deleted entites are gone, as they should be, but the ones which went through the boolean operation are not modified. On the screen they look like the boolean operation was successful. If i save the drawing manually, they are saved correctly.

Should I do more than committing the transaction before saving the drawing?

Thank you.

Document acDoc = Application.DocumentManager.MdiActiveDocument;

            Editor ed = acDoc.Editor;

            Database acCurDb = acDoc.Database;

Does the following snippet works for you? (run it in an empty drawing)

If so, you should search the context differences between this code and yours.

        [CommandMethod("TEST", CommandFlags.Session)]
        public static void Test()
        {
            var docs = Application.DocumentManager;
            var doc = docs.MdiActiveDocument;
            var db = doc.Database;
            var ed = doc.Editor;
            using (doc.LockDocument())
            using (var tr = db.TransactionManager.StartTransaction())
            {
                var cs = (BlockTableRecord)tr.GetObject(db.CurrentSpaceId, OpenMode.ForWrite);
                var sphere = new Solid3d();
                sphere.CreateSphere(7.0);
                sphere.TransformBy(Matrix3d.Displacement(new Vector3d(5.0, 5.0, 5.0)));
                cs.AppendEntity(sphere);
                tr.AddNewlyCreatedDBObject(sphere, true);
                using (var box = new Solid3d())
                {
                    box.CreateBox(10.0, 10.0, 10.0);
                    box.TransformBy(Matrix3d.Displacement(new Vector3d(5.0, 5.0, 5.0)));
                    sphere.BooleanOperation(BooleanOperationType.BoolIntersect, box);
                }
                    tr.Commit();
            }
            db.SaveAs(@"C:\Temp\BooleanTest.dwg", DwgVersion.Current);
            docs.Open(@"C:\Temp\BooleanTest.dwg");
            docs.MdiActiveDocument.SendStringToExecute("_-view _seiso\n", false, false, false);
        }

There are many minor differences between the codes, so i changed gradually your code to see if I end up getting the same error.

First i did the boolean operation between an existing sphere and a newly generated box. I ran Test in a drawing that was containing already the sphere.

Then, when I tried to open the drawing automatically, then do the boolean operation, i got the same problem with the boolean operation not being saved.

It's definitely something i'm not doing just before saving.

I attached the drawing that contains the sphere.

Thank you for your help so far.

Please see attached code:

[CommandMethod("TEST", CommandFlags.Session)]
        public static void Test()
        {
            var docs = Application.DocumentManager;
            string file = "C:\\Temp\\BooleanTest1.dwg";
            if (File.Exists(file))
            {
                Document almeu = docs.Open(file, false);
                docs.MdiActiveDocument = almeu;
                string drName = Path.GetFileName(almeu.Name);
            }
            else
            {
                docs.MdiActiveDocument.Editor.WriteMessage("File " + file + " does not exist.");
            }
            var doc = docs.MdiActiveDocument;
            var db = doc.Database;
            var ed = doc.Editor;
            using (doc.LockDocument())
            using (var tr = db.TransactionManager.StartTransaction())
            {
                var cs = (BlockTableRecord)tr.GetObject(db.CurrentSpaceId, OpenMode.ForWrite);
                foreach (ObjectId id in cs)
                {
                    Solid3d entity = (Solid3d)tr.GetObject(id, OpenMode.ForWrite);

                        entity.BooleanOperation(BooleanOperationType.BoolIntersect, box);
                    }
                }
                tr.Commit();
            }

I just tested your code and it worked fine.

Which version of AutoCAD are you using?

Re: Can't save boolean operation to disk.

Anonymous — Mon, 29 Apr 2019 15:16:54 GMT

2019 Vanilla AutoCAD.

Re: Can't save boolean operation to disk.

It works fine for me with 2019 Vanilla AutoCAD.

Perhaps some settings, but I cannot see which.

I discovered that it's a visualisation issue probably.

The boolean operation is saved, but i't not visible in 2d wireframe. any other visual style shows the objects as they should be.

Also, even if I am in 2d wireframe, if I orbit, it looks the right way, with the trimmed solids.

Can you open the attached file to see how it looks?

Thank you.

That's what I see when I open the file:

So the issue with is my computer. The code works perfectly.

when i open the drawing, it looks like this:

If i orbit, it looks like this:

When i exit orbit, it looks like this:

I'll have to figure out what's wrong with my autocad, but i can use the routine as is.

Thank you so much for all your help!

The solution was a workaround.

Instead of using database.saveas, the routine is copying the original file, runs on the new file and uses doc.closeandsave.

This way the weird display doesn't happen anymore.
