How can I get the capture point (endpoint, midpoint) of the model?

if you want to customize the capture point of the model by customizing an extension instead of opening the measurement, how can you implement it?


At a glance, the activation of the measured mode includes the toolbar and the initialization of snapper, while snapper includes the detection of faces, edges, vertices, and nearest points. Without entering the measurement mode, these methods do not work, and the method of simply detecting capture points has not been exposed.

but ask curiously. When you implement the capture point scene yourself, you don't want to have the viewer default measurement bar and measurement mode mouse (small ruler), as well as measurement lines, measurement values, etc., just want to capture point markers (identify breakpoints, midpoints, plumb points)?
