Do you ever find yourself performing the same point cloud task over and over again for larger datasets? A new tool available in 2015.1 Service Pack A may help by allowing you to run point cloud tasks from the command line. Named “LPRunPCT.exe”, this application contains a number of command line options and associated parameters for running point cloud tasks via the Windows Command Line Interface (CLI). This has proven useful for customers who perform large numbers of routine tasks, such as classifying ground, vegetation, or buildings over large areas. All you need to do is create a point cloud task, set its parameters, and then save that task as an .xml file. Then you are ready to execute that task using LPRunPCT.exe.
It is important to note that in order to run a point cloud task from the command prompt, a separate license instance is required.

However, I tried several times and it does work, and keeps telling me that my input LAS file should be in read/writing mode. I do not know how to using the commanding line to set this mode for my input LAS file.
Any information you can provide are appreciated. Thank you!
The Drape/Pure Drape method creates a vertex for every intersection with the TIN surface (Create more vertices). This best models the LIDAR surface in the geometry.
The summarize Z uses the selected option to determine from the source points the value to assign to the existing vertices or attribute table. Hence, it does not simply pull values from the TIN, it looks at, for example, all the Z values in the source points within the given geometry, i.e. distance from the feature, or vertex, or within the feature, depending upon the selected option, and then assigns the min/max/mean, etc. value.
