General Usage Instructions

See detailed description and help on each command for usage instructions in the commands section.



Ribbon/Toolbar Icon Command Command Description


Prompts for a file selection of LAS/LAZ files, which classes to use (separate multiples with a comma), then a rectangular window for your area of interest. Any points in a file that fall outside the window are not included. Any files selected that fall outside the AOI are not even scanned for points (saved time).


Prompts for a selection of files then converts them to LAZ for maximum compression and compatibility with the tools below. For maximum speed and file integrity, this tool uses RapidLasso’s LasZip for file conversions (with permission).


Creates a detailed report displayed in your default browser, ready to print. Includes point count, coordinate window, elevation min/max and optionally classifications and subcounts.


Create a LAZ file from Tin/Grid surfaces (classification 2 for ground). Includes a surface sampler that writes out points on a virtual grid (user supplies interval) draped onto the surface for reducing existing overly dense surfaces.


Plots selected lidar files as point objects in the drawing. Beware that Autodesk® AutoCAD® tends to slow down significantly and/or become unresponsive or unstable with massive amounts of points. A separate session is highly recommended.


Prompts for a selection of LAS/LAZ files, source and target system names. Then uses AutoCAD projection engine to convert the points to the new system (including elevation scaling). New file (with target code appended to name) stored in LAZ format using RapidLasso’s LasZip for maximum file integrity.


Creates a reduced point copy of a dense file with various filters. Currently includes Interval (very useful for contours only) and optional elevation min/max removal. Echos percent reduction of each file at command prompt.


Prompts for a file selection of LAS/LAZ files, then draws rectangles in model space representing the extents of those tiles. Label information includes file name, min/max elevation and total number of points. Optionally include classifications found and the number of points for each.
