Description

Provides info about coordinates, length, and angles in real-time next to the mouse pointer in a bubble annotation displayed in the 3D view

FCInfoToMouse macro in action

Usage

1. Install the FCInfoToMouse macro in your macros directory via the Addon Manager
2. Run the Macro

Result: an annotation appears and the mouse coordinate information is displayed in real-time.

Figure 1

• X, Y, Z: mouse coordinates are displayed in the bubble (this only applies when "Single" mode is enabled) as seen in Fig. 1

Once the mouse is clicked for the first time, additional info is displayed (when "Forced" mode is enabled this setting will be solely displayed)

Figure 2

• X1, Y1, Z1 : Initial coordinates of the 1st mouse click
• X2, Y2, Z2 : Current coordinates of the mouse
• L : Length between the first mouse click and the location of the current mouse pointer
• XY, YZ, XZ : Angles between the 1st point and moving mouse pointer in the XY, YZ, and XZ planes

Figure 3 - when mouse pointer is over an object, the name of the object will be displayed

If the mouse hovers over an object, the object name appears at the top of the annotation (see Figure 3).

Keyboard Shortcuts

SHIFT + Q: Quit the FCInfoToMouse macro. Upon quitting the macro, the annotation remains at its current mouse pointer location. Begin using the mouse normally if you want to delete the annotation manually.

SHIFT + M: Toggle the mode between:

• single which displays only the coordinates of the mouse pointer (Figure 1)
• force which displays the "comprehensive visualisation" (Figure 2)
• normal which displays the default behavior of the macro

SHIFT + C : for "hidden / visible"

SHIFT + D : to "Open/Close" a Spreadsheet with the coordinates saved to:

Cell A	Cell B	Cell C	Cell D
x, y, z	x	y	z

Notes

At any time, you can change the properties of the annotation by clicking the object FCInfoToMouse in Combo View and click the View tab

If you want change the number of decimal change the line 43 (default 4)

Example for 6 decimal places:

original value

global arrondi    ; arrondi    = 4

replace to

global arrondi    ; arrondi    = 6

To make the configuration of the permanent annotation you can change the values in the configuration section lines 104 to 122
