Point cloud?

Point cloud?

Point cloud?

(OP)
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

Btw, I'm using NX 6.0

RE: Point cloud?

Hi Johanna,
It seems to be a set of point data only.Point cloud (.stl files are one format) once imported inside NX gets faceted and then you can use a host of reverse engineering options to create surfaces on top of it (NX Shape studio has lot of them).
