Using 4.7.01 DX64 win 8.1 In sculpt room using Voxel mode I am using the cut-off tool with Circle Lasso I L.C. drag to activate then hit the spacebar and input my # and hit enter . All is good it is when I hit and hold the spacebar as to drag around to position the cut off circle that the Quick Access Panel comes up and when I mouse away I lose everything. I don't know if it has always been this way or its just a beta work in progress but I would think if I am in the middle of using a tool it should just hold my cut-off to let me drag and position it. A Request : A check box To Center Mass in the cut-off tool would take all the guess work 1,2,3, tries to just get it close enough and move on . Setting up the 2d grid is a option I know.
