Big Ben, officially known as the Elizabeth Tower, is part of the Palace of Westminster and one of London's most iconic landmarks. First completed in 1859, it is known for its precise timekeeping and grand design.

This model package includes the following formats:Native SketchUp 2020 file (.skp)Converted version: .obj

When using the .obj file in your 3D software, please note the following:Axis Orientation

　SketchUp uses the blue Z-axis as the upward direction by default. Depending on your 3D software, the imported model may require rotation (typically 90 degrees) to align correctly.

Material Adjustment　Reflective materials such as metal or glass set in SketchUp may lose their properties when imported via .obj.　To assist with this, a reference image is included showing which areas are intended to have reflective materials, so you can manually reapply them in your software.

Model Checking & Reliability　The .obj file has been imported into Twinmotion and tested multiple times. The model has been reviewed and refined to eliminate any major issues such as missing faces, broken geometry, or misalignments.　Due to the model’s complexity, there may still be rare minor issues like overlapping faces or slightly misaligned small parts.

Internal Structure Note　Internal areas of the model are not visible or intended for use, so they have not been fully refined. Some overlapping or intersecting geometry may exist in these regions, but they do not affect the model’s appearance or performance and are common practice in efficient 3D modeling.

Vertex & Edge Count Clarification　When converting .skp files to .obj, the way geometry is interpreted can result in different vertex or edge counts. The counts shown on the platform are based on the original SketchUp file. This is a typical and acceptable occurrence in file conversion.
