Hi Daniel i'm having some troubles when im trying to decrease the size of a las file (1.4), i save the file but when i open it appears a message saying "the third-party library in charge of saving/loading the file has failed" i have tried with 1.3 and it doesnt show any problem The issue i...

there is a plugin for reading IFC:

Hi Daniel, i didnt get any answer from the researchers (at researchgate.com) could you read it? do you think that it can be a good tool? so far i have talk with some colleagues and all of them they believe that can be a great tool

Hi Daniel

i dont have it but i just ask for it

Hi Daniel thanks for reading this topic Have you read the "Robust Extraction of 3D Line Segment Features from Unorganized Building Point Clouds" from "Pengju Tian,Xianghong Hua, Wuyong Tao and Miao Zhang"? looks nice method for 3D line extraction, that may help in a lot of areas....

Hi Daniel
Is there any option to import Topcon clr files?

Hi, i found the way to do it, actually I was busy, but yesterday it comes back to my mind, and the solution its easy to do it. M3C2 distances its key, just need to use the "tunnel" cloud and the lines import as a cloud. The cloud of the lines (bolts) needs to be import in ASCII format with...

yep, can be an option, but I'm talking about hundreds of thousands of lines, if I need to subsample all of them and later recognize the intersection it will be so time-consuming

it is useful for civil engineering, especially tunnel construction

i dont know if i will be able to show in a picture, but I will try.

The input will be several lines, coming from dxf for example, and a point cloud.
The idea is to find the intersection as shows the attached picture

Hi, I'm really searching for an algorithm to calculate the intersection between lines (more than one) and one point cloud, the result could be the lines but cut until the point cloud "intersection". it will be so useful for civil engineering, sometimes it is needed to calculate the length ...
