Creating a plot with a known radius

[tasimadhibha]

I am new to cloud compare and i want to find out how to create a plot of known radius and filter out any other point clouds outside the circular plot.

The only way I see would be to create a cylinder (with the Primitive Factory) and then compute the distances from your cloud to this cylinder (Tools > Distances > Compute Cloud/Mesh distance). Eventually use the 'Edit > SF > Filter by Value' method to keep the points with a negative distance (i.e. inside the cylinder).
