Is it possible to import Point Cloud data in BricsCAD?
Short Answer
Yes — BricsCAD can import point cloud data using the POINTCLOUDATTACH command, which is the standard professional method for attaching indexed scan files into a drawing. This is the fastest common workflow for visualization, tracing, and modeling from scan data. Limitation: BricsCAD typically requires supported, prepared point cloud formats rather than raw scanner files.
What You Need to Know Before
Warning: Point clouds often fail to attach because the source file is not in a supported indexed format or the referenced path has changed after attachment. Very large scans can also cause severe display lag if density or clipping is not managed early.
How to Import Point Cloud Data in BricsCAD
Command: POINTCLOUDATTACH
Shortcut: No default shortcut
Quick Steps:
- Go to the Insert tab on the Ribbon and choose the point cloud attach option, or type
POINTCLOUDATTACH. - Browse to the supported point cloud file, select it, and confirm the attachment settings.
- Set the insertion point, scale, and rotation, then enable a display option such as clipping or density control if needed for performance.
- Go to the Insert tab on the Ribbon and choose the point cloud attach option, or type
Variables & Settings
Key Setting: In the attachment dialog, verify the Path type option if available and prefer a relative path for shared project folders.
Expert Setting: A broken absolute path is a common reason attached point clouds appear missing when drawings move between users, servers, or BIM coordination folders.
Why it Fails
Cause 1 (Geometry): The point cloud file is not in a supported or indexed format, so BricsCAD cannot attach it correctly.
Cause 2 (layers/Locks): The point cloud may be attached on a frozen, off, or locked layer, making it appear missing or unselectable.
Cause 3 (Command/Logic): Users often try to open raw scan output directly instead of attaching a processed point cloud reference file.
Quick Fix & Best Practice
Quick Fix: Re-export or index the scan into a BricsCAD-supported point cloud format, then reattach it with POINTCLOUDATTACH using a correct relative file path.
Manager’s Verdict: Use point clouds in BricsCAD for coordination, tracing, and scan-to-model workflows, but preprocess large survey data before attachment to keep project files stable and usable.
FAQ
Can BricsCAD open raw laser scanner files directly?
Usually no — most workflows require a supported processed point cloud file.
Can I clip a point cloud in BricsCAD?
Yes, clipping is commonly used to isolate working areas and improve performance.
Why does the point cloud disappear after moving the dwg file?
The attached file path is likely broken and needs to be repathed or reattached.
