How to create poly from through hole drill hole or slot?

jtra

I need a way to create poly from a through hole drill or slot.

I thought this was easy by specifying hole of the pin as the option to create the poly.

Thanks

  • The ?holes option in the axlPolyFromDB is only for polygons which have one or more voids. A padstack layer (like etch/top) does not include a void of the drill hole.

    The only way I know of is to look at the padstack drillFigureName, drillDiameter, drillSizeWidth+width and drillOffset and create paths/poly's of the actual drill.

    In case of a slot you need the drillFigureWidth and Height. 

    Here is some code for a slot to a line. You can create a line path instead (xy1 xy2 with a width) and convert this to a poly.  The 'pin' variable is the pin dbID.

    if(pin->definition->drillSizeHeight > pin->definition->drillSizeWidth
    then dy=(pin->definition->drillSizeHeight - pin->definition->drillDiameter)/2.0, dx=0
    else dx=(pin->definition->drillSizeWidth - pin->definition->drillDiameter)/2.0, dy=0
    )
    xy1 = list( car(pin->xy)-dx+car(pin->definition->drillOffset) cadr(pin->xy)-dy+cadr(pin->definition->drillOffset) )
    xy2 = list( car(pin->xy)+dx+car(pin->definition->drillOffset) cadr(pin->xy)+dy+cadr(pin->definition->drillOffset) )
    xy1= axlGeoRotatePt( pin->rotation xy1 pin->xy)
    xy2= axlGeoRotatePt( pin->rotation xy2 pin->xy)
    axlDBCreateLine( list(xy1 xy2) pin->definition->drillDiameter "board geometry/dimension" nil pin->parent)
