Automation of Point Cloud Processing

[Anonymous]

Firstly, thank you very much for reading this post.

I have a question, which I need your help.

I wish to automate the process, since it is just a repetitive work. I wish to:

Import Point Cloud -> Attach -> rotate it so I can take appropriate cross section -> take multiple cross sections -> export to a new paperspace -> save file

Problem is that I still need to put in manual work to complete the task. For example, when inserting point cloud, I have to press enter after importing point cloud to set parameters. I am doing the task to multiple objects so automation is crucial, on every single bit.

Using scr file format, I have managed to Import PC and attached it, but my goal is to run the script which does the whole thing without my interaction at all.

Unfortunately, I have no experience with lisp so using it was proven difficult.

I need to know a couple things at least to start with, and I need to do them just by using command line and keyboard, which can be fully executed.

Firstly, how do I select a specific object using command lines? Like, if I wish to select PC with pre written command lines, what should I do?

Secondly, how do I set a variable so I can use the variable as a number? I wish to set z values of PC onto variables and conduct repetitive work.

And lastly, how do I perform 3d rotation without manually selecting axis? (So far, you have to manually select axis to rotate onto)

If these questions could be answered, that would be fantastic. Thank you!

If you already have a point cloud in the drawing then you need to either have the user interactively select the file or build a selectionset to automate the selection. Try below routine to start off. The user is asked to select rcp file. See here for selectionsets. Note that I tried with a sample rcs file and it works. I am assuming it should work for rcp file.

(defun c:somefunc ()
(command-s "._-pointcloudattach" (getfiled "Select rcp file" "" "rcp" 0) '(0 0) 1 0)
(command-s "._rotate3d" (entlast) "" "_y" '(0 0 0) 40) ;rotate 40 degrees about y axis
(princ)
)

Thank you very much for help, however I realised that I'm no good with lisp, so I just used simple command lines for now.

Do you know any way to implement Python into this like here?
