How to get cad block location

[chuongmep]

Hi @DomCR
Many thanks about this project, i have a problem when try get a location of cad block, how we can do that ?
Is this a development project in progress with it?

Hi @chuongmep

I'm guessing that the selection that you are showing in the image is an insert entity in the Model space in Autocad, first you need the BlockRecord called *Model_Space in the Document.BlockRecords which contains all the entities in the model space of Autocad, there you can look for the Insert entity that relates to this Block and check the property Insert.InsertPoint

I hope this helps, thanks for the support.

I've also created a release fixing the link between the Entities.Insert and the BlockRecord
release

@DomCR you have any sample for this , i have try but it return null object

 string file = @"C:\Users\Chuong.Ho\Desktop\Drawing1.dwg";
            using (DwgReader reader = new DwgReader(file))
            {
                CadDocument doc = reader.Read();
                foreach (BlockRecord blockRecord in doc.BlockRecords)
                {
                    if (blockRecord.Name == "xxx")
                    {
                        Console.WriteLine(blockRecord.Name);
                        CadObject cadObject = blockRecord.BlockEntity;
                        // can help me ? 

                    }
                }
            }
            //Console.WriteLine($"file read : {file}");
            Console.ReadLine();

Try this:

static IEnumerable<Insert> getInsertEntities(string file, string blockname)
	{
		CadDocument doc = DwgReader.Read(file);

		// Get the model space where all the drawing entities are
		BlockRecord modelSpace = doc.BlockRecords["*Model_Space"];

		// Get the insert instance that is using the block that you are looking for
		return modelSpace.Entities.OfType<Insert>().Where(e => e.Block.Name == blockname);
	}

This method gets all the Insert instances in the drawing using an specific Block.
