about extract feature line of a point cloud

[zhuhaixiong]

I want to know how to draw line in CC, can segmentation tools do this?

[daniel]

Well it can, but the easiest way is to use the 'Trace polyline' tool.

thanks for your reply!
the Trace Polyline Tools can draw a feature line point by point?
I wonder how to draw a line in this tool.

Simply draw a polyline over a point cloud.
