The proportional editing tool use a white circle as an indicator to which vertice are affected but that works in 2D world well and not 3D.(for example if you design a flat paper page in blender and view it from top it works 100% accurately) enter image description here As you see in the image above some vertice are within the circle but they aren't affected.Is there a more accurate way to know which are affected?

    $\begingroup$ View it from the top and you'll find they are within the circle. Consider the guide as a "sphere" around the vert (or median point of verts) when first selected. $\endgroup$ – batFINGER Aug 31 '16 at 14:34

    $\begingroup$ can you explain?, mentioned view from top in context to your screenshot as you have translated in what appears to be a global z direction. $\endgroup$ – batFINGER Aug 31 '16 at 15:05

    $\begingroup$ Consider using quad view or multiple views to see more. Consider circle select. Consider Hide Vertices to prevent movement. Even though Hide Vertices has limitations. $\endgroup$ – atomicbezierslinger Aug 31 '16 at 17:39

This script / addon may help. It simply selects the vertices impacted by the proportional editing, starting from the current selection.

Once visualized, you can Ctrl+Z to come back to your current selection.

    $\begingroup$ Is there a possibility to display the impacted vertices with weight colors while doing proportional editing? $\endgroup$ – Denis Aug 31 '16 at 17:49
