Symbol Editor: Moving Axes to Background Such That Graphical Elements are not Covered

sgcad

Hi

In the symbol editor, I like to enable the axes display such that I can easily align the origin of the symbol to where I like. But the axes cover graphical elements, in particular the rectangular outline of the symbol:

Is there a way to change the order of the displayed layers such that the axes (and ideally the grid dots as well, but that's far less disturbing) are in the background, and on top I'd see the green outline of the symbol?

Thanks very much for your response.

    This is all to do with the layer purpose priorities in the tech file. You can adjust this by doing this (say):

    tf=techGetTechFile(geGetEditCellView())
    axis=techGetLP(tf list("axis" "drawing"))
    grid=techGetLP(tf list("grid" "drawing"))
    grid1=techGetLP(tf list("grid" "drawing1"))
    techSetLPPriorityInContext(tf axis 1)
    techSetLPPriorityInContext(tf grid 2)
    techSetLPPriorityInContext(tf grid1 3)

    You should make sure that the grid/drawing1 has a higher priority than grid/drawing as otherwise the major grid may get obscured by the minor grid.

    Is it possible to read or modify the value for the major grid spacing from here?

    I tried grid~>?? but it did not return any meaningful numbers

    This should really be a new question (see the forum guidelines), but for an existing window it is:

    hiGetCurrentWindow()~>gridSpacing=0.125 ; that's the default for schematics and defines the minor grid
    hiGetCurrentWindow()~>gridMultiple=8 ; that's the default for schematics and defines the number of gridSpacings between major grid points

    There are also two cdsenv variables to control the defaults for new windows:

    schematic                          schGridSpacing                                                 float    0.125
    schematic                          schGridMultiple                                                int      8
