To import point cloud in ARCHLine.XP follow the next steps:

In the dialog that appears, select the point cloud file you want to import.

Supported Formats Overview

NATIVE POINT CLOUD FORMAT (*.APC)

ARCHLine.XP 2026 introduces a new native point cloud format (*.apc) that enables fast saving and reloading of processed point clouds.

After optimization operations such as decimation, area cropping, or deleting unnecessary regions, the reduced point cloud can be saved directly to disk in the optimized format.

The *.apc format provides significantly faster loading times, improving the handling of large point cloud projects while reducing memory usage and project opening time.

Once you have selected the point cloud file ARCHLine.XP will process it and place it one of the following ways:

 1. Default:                 ARCHLine.XP places the center of the point cloud bounding box at the global origin.
 2. Use Geolocation:  ARCHLine.XP places the point cloud using its real-world geographic location.

Where can it be set? 

Options - Item Settings - Point cloud
