Hi Chris - wecome to the forum
Not sure exactly where you are in the process but here's a general guide.
Do your 2.5D probe round your object to create the edge profile.
Then do your 3D probe using that profile as per the readme. This will create a "triplet" file of the x,y and z values at each probe point. This file has a .csv (comma separated values) extension.
I've never used MachCloud but I just took a look and it expects a .txt extension. So just change the .csv to .txt and MachCloud will load it.
Now you need to use MachCloud to "drape" the points with a "surface". I did this just now via the Mesh/Ball pivot mesh menu option. You'll see MachCloud "drape" your points. Then you can save that as a .stl 3D model file.
After that I'm not sure what else MachCloud can do for you - as I say I've never used it, but I don't think it does any CAM functions but I'm sure someone will beat me up if I'm wrong
.
So what you need to do then is use some CAM software to create a toolpath from that .stl 3d model. Do you have any CAM? If not hopefully somebody will chime in with recommendations.
Personally I use Rhino and RhinoCAM.
Hope this gets you a tad further.
Cheers
Ian
