This allowed us to port this popular collection of free tools to BricsCAD. #Wxgui.dll bricscad zipĪs of the (DotSoft ZIP File) download below also includes DLL files for these BricsCAD versions! The only tool that doesn’t work in BrisCAD is LIDARPROJ (process works in our MapWorks product). 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).Ĭreates a detailed report displayed in your default browser, ready to print. Includes point count, coordinate window, elevation min/max and optionally classifications and subcounts.Ĭreate a LAZ file from Tin/Grid surfaces (classification 2 for ground). Includes a surface sampler that writes out points on an 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 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’s 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.Ĭreates a reduced point copy of a dense file with various filters. Currently includes Distance (ignore points closer than specified to other points), Interval (useful for contours) 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. 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). This means you can have a massive collection of Lidar files (smaller tile the better) and simply select them all, window off your area of interest and in a short wait, have a TinSurface object ready to work with. We included support for LAS purely for convenience, but the best file format for your Lidar data present and future is the LAZ file format. It typically consumes about 18% of the space the LAS (or Recap) formats would, and roughly 1.5% of the space an ascii XYZ file would! Other considerations. All major lidar products support the LAZ format for read/write.The file format is open, documented and free libraries exist for it.There are numerous tools available to manipulate these files.So next time you order Lidar data, tell your provider “LAZ Format” please. Also specify maximum granularity since each small LAZ tile has a bounds header, software can skip an entire file if it’s outside your current area of interest.
