Grid Offset

I am missing a possibility to enter an offset or zero point to the grid I selected, With the different Pitches and the mix of inches and metric I often have to switch and it would realy help if I could switch the offset to.

 

Kind regards

 

John

the MARK command is not sufficient for this ?

NO. It affects only display and allows for "relative" coordinate entry,

but it does not modify the grid "snap" for any mouse movement.

The current grid behaviour has at least two problems that get

increasingly annoying with 'modern' electronic components:

  1. As stated above, the grid should have a selectable origin, so

     that the snapping works properly.

     This is not SO important for the package editor, but for the

     'real' board: There, one sometimes has mechanical restrictions

     like 'this part MUST go here, and those LEDs should each have

     0.1" distance from THIS point which, unfortunately, is NOT

     on the grid'. It IS possible to solve this problem now, but

     only with a piece of paper and manual coordinate entry.

  2. It should be possible to have a DIFFERENT grid distance for

     horizontal and vertical directions.

     This is not SO important for the board editor, but for the

     package editor: Though I thoroughly HATE components that have

     a millimeter grid in one direction and inches in the other,

     such bloody components DO exist. And components with different

     inch grids in both directions are not SO rare. At the moment,

     this can only be solved by manually switching between grid

     settings a thousand times.

I suggest the following:

  3. Introduce three additional keywords for the GRID command:

      - VERT: Works like the ALT keyword, only that following

        characters change the VERTICAL grid settings

      - HORZ: Ditto, only with the HORIZONTAL settings

      - ORIGIN: Must be followed by a point (x,y)

     If none of these is given in the command, it behaves just

     as usual. Examples:

      - GRID Inch 0.1 Lines On;  [sets 0.1" in BOTH directions]

      - GRID Horz Inch 0.1;      [sets 0.1" horizontally AND

                                  LEAVES THE VERTICAL GRID

                                  UNCHANGED]

      - GRID Horz Inch 0.1 Vert mm 3.75;

      - GRID Origin (1inch 2mm);

      - GRID Origin (1inch 2mm) Horz Inch 0.1 Vert mm 3.75 Lines On;

     The only things that I don't know at the moment is a) how to

     define the ALT grid horizontally or vertically and b) what to

     do with the multiplier.

  4. Lines/dots and on/off should always work for BOTH directions.

  5. The grid dialog should be changed accordingly. I'll think about

     this and mail you again.

In many cases the alternate grid should also be helpful.

You can have different units for both grids, but I agree, such extensions

sound reasonable. Thanks !
