Anyone who has used point cloud and can tell me how it works?
Or rather, how much data it can process without getting "confused"...
I managed to insert around 6500 points succsessfully, but it didnt manage to create any surface...More luck than skills just managing to insert the points
Had some corrupt data I think.
So how does NX "like" it's data? What is the perfect input? (I've never done anything like this before) In the ".dat"-file, how is the coordinates supposed to look; spaces between/commas/?
The thing is, I'm modeling a bevel gear/pinion shaft, and to get the correct geometry I'm first using becal twice, and after that some "home-made" program that "read" the geometry and creates a huge amount of .dat files. Each file contains a string of coordinates wich describing either the flank or the cross-section. And from there, I'm inserting splines through points from each file. And I've only managed to insert one spline at the time... And from there, a through curve mesh, and a wicked instance geometry, and I have a somewhat correct model. I get a small angular misinlagement, but I can survive with that...
So here's our idea: It should be possible to re-write the program so the output is in one single file, and be a clean set of coordinates. And from there, use the point cloud... But since NX is easily confused, whats the limit? How many points should I try to limit the cloud to?
How is the positioning supposed to be in the .dat file?
Or does anyone have a easier way to go?
Cheers, Johanna
