Diferences on the file created by AcadSharp

[thaiguer]

Hello,

I used the following code to copy entities from one file to a new one:

using ACadSharp;
using ACadSharp.IO;

Console.WriteLine("Hello, World!");

string sourceFile = @"C:\dev\tablet.dwg";
string targetFile = @"C:\dev\just a drawing222.dwg";

using (DwgReader reader = new DwgReader(sourceFile))
{
    CadDocument doc = reader.Read();
    CadDocument newDoc = new CadDocument();

    foreach (var entity in doc.Entities)
    {
        doc.Entities.Remove(entity);
        newDoc.Entities.Add(entity);
    }

    using (DwgWriter writer = new DwgWriter(targetFile, newDoc))
    {
        writer.Write();
    }
}

I attached the source and the target file. files.zip
The problem is that there are a few differences and some missing entities in the target file.

Problem 1: Hatches missing inside Block References

Problem 2: Different color on a ByLayer Entity

Problem 3: OLE 2 Entity missing

Hi @thaiguer,

The first problem seems to be related to the Hatch entities, I guess that is something related to the patterns, I have to take a look.

The second problem I've found an error in the Layer clone method.

I'll open 2 branches to fix this issues.

Thanks for the report!

Hello,
The problem 2 seems to be fixed, thanks for the correction.
Although, the Problem 1: Hatches missing inside Block References, is still happening.

Take a look at a image from the source file:

And take a look at a image from the target file:

The Hatches missing inside Block References problem is solved. 👏
Here is an image of a file copying the entities from the existing DWG to a new one:
