Shifting while point picking to draw a line.

[Hema]

I have a point cloud data which I have loaded in the cloud compare tool. I am picking the points continously to draw a line(my application is to draw the white lines on the huge GIS data), If I ZOOM IN, the precision of the picked point is good, Since it is a larger data I cannot always zoom in and pick.
So if I ZOOM OUT and pick a point, some other points will be picked(there is a random shift) and its not consistent, is there any work around for this or suggest any rectification for the same, If you guys need any clarification further I can give more info on the issue.

Are you using the 'Trace polyline' tool?

If yes, then you can keep a high level of zoom, pan the view with the right mouse button, then click on the '+' icon to continue the current polyline edition.

I appreciate the timely response and thanks for developing this awesome open source tool. Although your solution will solve that problem....
But I have the task of doing annotation for the data size of around 2000 km, and zooming in and out will be tiresome and exhausting, all i am trying to do is do the annptation or draw the polyline in zoomed out stage. I also don't mind adding a new button or new functionality, please do suugest, will be waiting for the reply..............

Well, since you are zoomed out, there's probably dozens if not hundreds points in one pixel. There's no way CC can choose 'the right one' magically...
