Select sub-objects using closed boundary curve

[jdelavaulx]

Hi there,

I’m working with a large pointcloud, and I need to delete many of those sub-object points and the quickest way would be a closed curve boundary. Is this possible?

HI David, thanks for your reply

I have the sub-objects button checked, and then use the selboundary command, but it doesn’t work. It only works when it’s regular points, not subobjects of a point cloud

Hi Jeremy -

@jdelavaulx

I have the sub-objects button checked, and then use the selboundary command, but it doesn’t work.

That seems to work fine here in a simple test case with 20 or so points turned into a pointcloud.

Which version of Rhino are you running?

It might be a bit unwieldy, but you can run the PointCloud command, pick the Remove option and use something like SelBrush to grab the points you want to remove.

Ah, yes, SelBoundary does seem to work here, but with the Selection filter set to SubObjects, one needs to use Ctrl+Shift+Pick to pick the boundary curve. Then hit Delete.
