If I want to draw some vertices on the ground plane, I seem to have to place the first vertex with Ctrl-+RMB (not Ctrl-+LMB as the manual states...), then Extrude the rest of the vertexesvertices using E...which, which is fine, except that using Ctrl-+RMB seems to ignore my snap to grid settings (using E behaves properly), so I can't accurately place that first vertex.
Is there a way of making that snap when it's placed, rather than having to move it afterwards?
This is in using Blender 2.8 btw?
