Converts point cloud files to BricsCAD BPT format
Accessing the Command
Keyboard: pointcloudpreprocess
Toolbar: Point Cloud
:PointCloudPreprocess
Displays the Point Cloud Data File dialog box:
Choose a LAS, PTX, or PTX file, and then click Open. The program displays the Give Name for Preprocessing Output File dialog box.
Choose a folder in which to place the BPT file, and then click Save. The program prompts you:
Start preprocessing of raw point cloud data?
This is a necessary step, but will take ~1 minute per million points. [Yes/No] <Yes>:(Press Enter to continue)
Give unit for point coordinates. [Inches/Feet/Miles/miLlimeters/Centimeters/mEters/Kilometers/micrOinches/milS/Yards/Angstroms/Nanometers/micRons] <mEters>: (Specify a unit type)
Chosen units are Meters
Preprocessing data: C:\Users\ralphg\Desktop\Dropbox\dwg\Point Clouds\3D part.bpt -> This will take apprx 1 minute per million points source data.
The program processes the points in the background so that you can carry on working on drawings. The processing time can take from several seconds to several minutes. When done, the program displays a dialog box with the results of the conversion:
When the program reports the conversion is completed, use the PointCloudAttach command to attach the BPT point cloud file to the current drawing.
Command Options

| Open |
Opens the point cloud file, and then prompts you for options. |
| Start preprocessing of raw point cloud data? |
Large files can take a long time to process, and so you have the choice of not proceeding with the conversion:
|
| Give unit for point coordinates. |
Specify a type of unit, in case the point cloud needs to match a model in the drawing:
