My artwork didnt work as intended....any advice?

hohk

Hi,

 

1. I created a PCB layout with only traces on the top and bottom layer connected to a padstack (modified to be a through hole).  

2. Manufacture> Artwork > Create Artwork (i choose gerber Rs274X, checked bottom and top films). In the end i had a TOP.art and BOTTOM.art.  The photoplot.log shows DRC errors but i ignore it since i only want to test outputing gerber files.

 3. When i import>artwork> TOP.art and choose Class = Etch and Subclass = Top, i get the top trace and the pad (green color). BUT, when import BOTTOM.art, and choose Class = Etch and Subclass = Bottom, i still get the top layer trace and pad only but in a different color (yellow).

 

So,  why cant i get the bottom trece and pads only when i impport the BOTTOm.art? Is my concept wrong?

 Thanks. Attached is my sample board file. Its just a test since i am new to PCB Editor. Hope some one can give some advce.

    Thanks for the advice and pointing out my mistake.

    Another question(s).

    1. If my board has lots and lots of non plated through holes of many different sizes, i have to create padstacks with pads smaller than the drill holes right? Is there a way to position them accurately by typing in coordinates (i have enginerring drawings) rather than using closely spaced grids?

     2.  If one of the through holes have large diameter (15mm), the PCB house said they have to route out the hole, does this mean that they will use a smaller drill bit and just cut along the circumference of the hole to create the hole?

     

    Thanks.
