Hi,

I'm trying to run the command

blast2iso64 -i JAS1133_gnd_thin_0.2_1.las -smooth 10 -clean 10 -iso_every 0.25 -o JAS1133_contours_1.shp

which I've done before and seems like it should be fine, but I'm getting the error (using LasLook)

LAStools BLAST blast2iso (by in...@rapidlasso.de) version 250917 (academic)

Hi Glen,
blast2iso64 was part of some beta versions and is still in test mode.
It is not released for production use yet. Please use blast2iso right now. blast2iso should work very well and right now there is not much reason to use blast2iso64.
Nevertheless, we will finish the port of blast2iso64 and will release it soon.

Cheers,

Jochen @rapidlasso
