Scan Radius and Layout Base Settings?

Hello there,

I just downloaded the trial version of PointCab. Unfortunately I never really worked with Point Clouds or laser scanning in general so I am very unexperienced. I wanted to import some of your example datas but I am stuck already at the beginning by not knowing anything about the capacity of this software. Maybe there is someone who can help me exploring PointCab step by step?

My first question would be, what the scan radius (layout base settings) means and how it affect my results?

sincerely,

paul
