Ole2Frame coordinates (UpperLeftCorner, LowerRightCorner) not written to DWG

[psitkei]

Description:

When exporting an Ole2Frame entity to DWG format, the UpperLeftCorner and LowerRightCorner properties are not written to the file. The OLE object appears in the DWG but at incorrect position (0,0).

Steps to reproduce:

Create a new CadDocument
Add an Ole2Frame entity with specific UpperLeftCorner and LowerRightCorner values
Save as DWG using DwgWriter
Open the DWG in AutoCAD or TrueView
The OLE object appears at (0,0) instead of the specified coordinates
Expected behavior:
The OLE object should appear at the coordinates specified by UpperLeftCorner and LowerRightCorner.

Environment:

ACadSharp version: 3.0.8
.NET version: 8.0

Workaround:

Currently converting OLE objects to RasterImage (IMAGE entity) for export, which correctly preserves the position.

Hi @psitkei,

The object Ole2Frame has been introduced in this PR, version 3.3.5:

• Issue 750 ole2frame #752

The Ole2Frame entity is created using a Binary data that I'm not sure how is saved, right now the Ole2Frame only supports the rewriting of the entity without modification in dwg, due the points being saved inside the binary data.

I'll open a branch to see if I can find anything else and improve the writer.

Thanks for the report!
