Point Cloud Converter Needed

Help! Do you have any suggestions on how to convert 3D point cloud
data into something useful (STL, DXF, ...)? I finally got my homebrew
laser stripe digitizer working enough to get good data out but now
that I got it I'm not sure what to do with it. A couple of hours of
Google searching didn't turn up anything too hopeful. I've got
STLTrans which supports XYZ input but I haven't been able to make it
work yet.

Any help appreciated. I don't want to re-invent the wheel or build a
Rube Goldberg if there is some easy way to do this.
