1. Q: How to make everything in 'mm' scale?
   A: File→document properties (Shift+ctrl+D)→Page:: Default units: mm, Grids:: New→Enabled,visible,Grid units: mm, Spacing X: 1.0, Spacing Y: 1.0, major grid lines: 10
2. Q: How to disable stroke scaling?
   A: File→Inkscape preferences (Shift+Ctrl+P)→Transforms→Scale stroke width.
3. Q: How to modify real size of object (discarding 'visual' stroke width)?
   A: File→Inkscape preferences (Shift+Ctrl+P)→Tools→Bounding box to use: Geometric bounding box
4. Q: How to show all objects without strokes (draft mode)?
   A: Ctrl+num 5
5. Q: How to rotate objects? How to choose pivot point?
   A: Left click (select), again Left click (rotate mode)→Drag "plus sign" (it is a pivot point) to desired location.
6. Q: How to move whole object using control point superposition? (selected point of an object shoul travel exactly to desired location?)
   A: Select object, move mouse pointer over desired object's point, hold Left button and drag it over destination point.
7. Q: How to make an array of object?
   A: Select object, Edit→Clone→Create tiled clones→Symmetry::P1,Shift X Per Column:: 100%, Rows, columns: 1 x 5. Create.
   N.B.:
   • Only objects having "Width" could be tiled (You SHOULD NOT waste time on tiling lines!).
   • Only ``geometrical bounding box'' without stroke width is taken into account!
8. Q: My object is ignored when Area or Path to gcode or I cant even "select it", e.t.c.
   A1: Try select object, Path→Dynamic offset (Ctrl+J)
   A2: File→save as "temp.ps" (postscript), File→Open "temp.ps", select desired object→copy→paste it back to original document.
9. Q: How to convert object to path? "Check that all paths are actually paths"
   A: Select object→Path→Object to path (Shift+Ctrl+C)
10. Q: How to find out outline orientation?
    A: Select objects→Ctrl+shift+F→Stroke paint:: Flat color (first box, after `X' mark), Stroke Style:: width: 1mm, End Markers: Arrow1End. Every outline will show their's orientations.
11. Q: My outline is milled counter clock wise but I want to clockwise path!
    A: Select outline→Path→Reverse
12. Q:
    A:
