FreeCAD: Your own 3D parametric modeler

Description
Macro Delta xyz
Gives the Delta values and distance between 2 points. Start the macro Select the first point in 3D view Select the second point in 3D view If the "SHIFT" key is pressed, the Delta value begin on coordinate 0,0,0 to point clicked (the coordinate 0,0,0 is displayed in red). One option is possible for the macro stay resident (continuous) then push "Q" key to quit the macro, and option for impose the number of decimals or use the decimal in the preference option.

Description

Gives the Delta values and distance between 2 points.

If the SHIFT key is pressed, the Delta value begin on coordinate 0,0,0 to point clicked (the coordinate 0,0,0 is displayed in red).

One option is possible for the macro stay resident (continuous) then push Q to quit the macro, and one option for impose the number of decimals.

Usage

Start the macro
Select the first point in 3D view
Select the second point in 3D view

If the SHIFT key is pressed, the Delta value begin on coordinate 0,0,0 to point clicked (the coordinate 0,0,0 is displayed in red).

If its is configured "Permanent" (continuous), click the Q key for quit the macro

Configure

For modify the value : go to : FreeCAD → Menu → Tools → Edit parameters... → BaseApp/Preferences/Macros/FCMmacros/Delta_XYZ.

_____switchDecimalsPref_____

true 1 : the round value takes the global preferences value
false 0 : the round value takes your choice

_____setArrondi_____

set your choice round value
if your choice = 0 : the round value is 3 by default

_____switchResident_____

true 1 : the macro stay resident (Type Q to quit)
false 0 : the macro is used on run and quit after use
