Yes, Shane is right! (it took me some time to reactivate my account after I lost my password )

Re: 2.5D volume calculation
Shane, Daniel, thanks for your responses, appreciate it.
Shane, do you perhaps have a youtube demo video of SCC showcasing this procedure or similar?
Daniel, is there any method in CloudCompare that can overcome this? (really annoying when one loses a password, yes!)
At this point I've 3D modelled the point cloud in a modelling package for the result. This takes time, so it would be a great addition if either SCC or CC can make this a faster process.
Thanks!

Re: 2.5D volume calculation
Hi Tertius,
The following video from 2017 shows you how to do this using a couple of different methods. The main difference is SCC is creating separate meshed surfaces (TIN models) for both the main model and the boundary model and using these to measure the volume, firstly using a prismoidal isopachyte method and then an end areas sectioning method. Not shown in the video, but a regular grid method is also available.

The mesh is useful here as it resolves how levels in areas under scan shadows are interpolated, it can also be edited where needed, to introduce any potentially missing break-lines. Personally, I'd also advocate well defined boundaries and illustrated boundaries when computing and delivering volumes to remove any possibly ambiguity in the precise area being measured. If you'd like to have a go with SCC you can download a demo license from our website here https://atlascomputers.ie/download/

Re: 2.5D volume calculation
Great, thanks Shane! This is helpful. I'll have a look at some more SCC videos as well. Will also the give the software a trial. Just need to see if my volume calc client base will grow in the near future.
