Place Bound Issues - Silk

archive
archive over 17 years ago

I created a part for an electrltic cap,  placed the "+" with lines in the package geometry Silkscreen_Top subclass.  When then part is placed in the layout file, the placeboind extends are not the place bound area I defined in the PLACE_BOUND_Top subclass, but rather extend to include the area of silk "+" of the part.
Futher more it appears that I can not create a circuluar place bound.

I've attached a jpg of the issue.

Any ideas would be most welcome.

    I think if you create a PSM part and don't include a placebound, it auto-adds one when you place it in the board file that encompasses everything in the symbol.

    To create a circular placebound, I just go select Shape->Circular from the menu bar, and set the proper class/subclass in the options tab.

    This is precisely what we have done.
    Here's a link to a .jpg that shows this.

    BTW, if the Silk "+" was created on the Board Geometry Silkscreen_Top subclass the place bound would be a rectangle bounding the boundary's of the silkscreen circle, note not a circle.

    The Place_Bound_Top must be a filled shape and in looking at your image "http://i59.photobucket.com/albums/g297/wildwpe/Capture-4.jpg" it is a circle.

    Delete the circle and redefine it using Shape -> Circular as Randy indicated and you should be fine.

    Hope this helps,

    Aha!
    Figured it out, the librarian created the place bound with a circle, not a shape!
    Thanks.....

    Agreed. Did you possibly do Add->Circle instead of Shape->Circle?
