Do you have return numbers, class codes, intensity values, etc., that you need access to? What do you intend to do with your lidar data? Going to LAS may not be your best option.
There are several websites that provide LAS files. I have tested ArcScene 10.1 beta with some of the LAS files located at http://liblas.org/samples/.
LAS file "2398_400.las" contains RGB values.
Alternatively, you could use software to convert your text files to LAS. I have installed LP360 (30 day evaluation) and it can convert text files (like PTS) to LAS. Make sure to choose LAS version 1.2 in LP360 to enable RGB.
Good luck!
I got LiDAR-data from a guy that said it was ascii. file-format says .cenz. Anybody heard of .cenz? when i open the file in texteditor: Class x y z
How can i make a pointcloud out of this?

The suggestions mentioned above (using LAStools to convert the ASCII data to LAS) are still valid. Have you tried that?
And if you download LasTools these days, it comes with a bunch of Arc style Toolbox tools.
Very good tool set.
If i try txt2las it says invalid filetype. I manage to make shape-points of it by adding the data into excel and then export as csv and the create points from XY. Then i tried to run shp2las but always when i try to use LasTools i get error. Could that be a licence issue?

The toolset is free as far as i know.
Are the files still names *.cenz?
Try changing the extension to txt
I did try and still got error using txt2las. I will redownload LasTools and try again. I did also try using FME xyz point cloud -> LAS did go through but nothing showing.
It´s also very big amounts of data so i did try everything with just a few points. Didn´t work.
I did try the new update of LasTools and i didn't work. As you can see above i have 4 columns: Class x y z. Could that be the problem? when i try FME the program only reads the first 3 columns and it doesn't work. I have lots of rows so it's not possible to import in excel an delete the first column either. Any ideas what i could try next? I have also tried to make a shapefile with points and then transform to LAS in FME, didn't work. In txt2Las i tried to change the phrase string to cxyz, c=classification.
The files i got was in an unknown format to me, .cenz. How did you mean i should make it a .txt instead? I did copy the data in to a txt-file. Maybe that's a problem?
Thanks for your time,
Anton
