I’m working on a series of projects–specifically creating topographical maps for use in games–where I want more precision in placement of vertices than the principal Blender interface is designed to provide easily. There is a defined set of vertices (specifically a contour) that I want to have a particular translation value, for the case of discussion here, let’s assume 51.09688 units on the Z axis.
At present, one of the available options I know about are to zoom in progressively using the appropriate view, and move the set along the z axis using a combination of mouse, or mouse and arrows. The other available option I know about is to mouse over to the z number button in the translation panel of the properties shelf of the 3D viewport, click on the number button, and enter the number manually, using the numeric keypad or the number buttons at the top. Both of these are more time consuming and involve more mouse movements than I’d like. It would be extremely useful to have a hotkey or shortcut that I could press that would allow me to access these number buttons with a couple of keystrokes, but I have not been able to find one. Is such a set of hotkeys already defined, perhaps as an add-on, ro which is otherwise playing hard-to-find? If one does not exist, is this an idea worth proposing as a new addon, or a new feature of the Blender interface.?
In more detail, the functionality I am proposing is that with at least one object selected in a blender scene, and the viewport set to object mode, pressing the key sequence “QUOTE G-key”, followed by X, Y, or Z would open the transform panel, and select the X, Y, or Z number button for keyboard entry and the X, Y, or Z attribute of the object would be set; when the entry in the number button is completed, the RETURN / ENTER key would close the keyboard entry, and return control to the mouse. I would expect this shortcut to work the same way in both object and edit modes.
Similarly, in object mode, the key sequence “QUOTE S-key”, followed by X, Y, or Z would open the X, Y, or Z number buttons in the Scale panel of the properties panel in the 3D viewport, the sequence “QUOTE R-key”, followed by X, Y, or Z would open the buttons in the Rotation panel in the 3D viewport, and “QUOTE D-key”, followed by X, Y, or Z would open the number buttons in the dimensions panel. Since by default, the Scale, Rotation, and Dimensions panels do not open in the properties panel in edit mode, these key sequences would not be implemented in the #D viewport in edit mode.
So, a good idea whose time has come, not here yet, or of current utility?
