Matterport E57 to High-Density XYZ for Archicad

’m looking for a point-cloud/BIM specialist to help resolve a file compatibility issue between a Matterport Pro3 E57 point cloud and Archicad 28.

Project background

I scanned an approximately 100–120 m² furnished apartment using a Matterport Pro3 at Medium Density. The scan consists of approximately 56 scan positions and was captured for an interior designer who needs a sufficiently detailed point cloud to model the existing property in Archicad 28.

Matterport generated an E57 point cloud of approximately 6.54 GB.

The problem

• The original Matterport E57 opens successfully in CloudCompare and contains the required level of detail.
• Archicad 28 rejects the original E57 as invalid.
• Matterport's MatterPak also provides a cloud.xyz file. This imports correctly into Archicad 28, but the client has confirmed that the point cloud is too sparse for the required interior-design work.
• We have already tried opening the high-density E57 in CloudCompare and exporting/converting it to XYZ. The resulting XYZ imports into Archicad, but strange circular artefacts appear in the point cloud.

Required outcome

I need the original Matterport E57 processed into a clean, high-density XYZ point cloud that imports correctly into Archicad 28, without the circular artefacts, while retaining substantially more point-cloud detail than Matterport's standard MatterPak cloud.xyz.

I am NOT currently looking for a BIM model or CAD model. The required deliverable is the processed point cloud.

Ideally, I would like the successful freelancer to:

Review the original Matterport E57 and existing XYZ examples.
Identify the cause of the artefacts/compatibility problem.
Produce a small test/sample XYZ first for validation in Archicad 28.
Once the sample is confirmed, process the complete apartment.
Briefly explain the processing workflow used, as I regularly capture Matterport Pro3 data and may have similar projects in future.

I can provide the original Matterport E57, the original MatterPak XYZ that imports correctly, screenshots of the Archicad error/artefacts, and other Matterport project files if required.

Please only apply if you have genuine experience processing E57/XYZ point clouds. Experience with Matterport Pro3 data, CloudCompare and/or Archicad is particularly relevant.

In your proposal, please explain briefly how you would approach the problem and mention any similar E57/XYZ conversion work you have completed.
