Hello.



I'm trying to figure out why I can't seem to get CadStar to print out

apertures on some simple pcb designs.



The version I'm using is antique, V2.4.1, which is used as I

understand it, because it's simpler for students than a more up to

date version.



Trouble is, when I print out the copper layers I get the tracking

& the pads but the pads are blind without the aperture which

means that once I've produced a pcb there's nothing to guide the

drill.



I've used other pcb software previously & this has never been a

problem.

With a lot of packages that is the default because the holes are drilled
automagically. There is usually some way to enable the holes for manual
drilling. If no-one else can help I know the people who worked on the
original CADSTAR, they subsequently set up their own PCB software company
and I use their software.

Cadstar does not include a "hole" in any pads unless the shape is defined as an
annulus (which I have never used in 15+ years of cadstar work).
When post-processing, the only thing you can produce is a "drill detail" which
identifies each hole size by a letter. Normally you would produce an excellon
file for use with an NC drilling machine.

V2 was a long (long) time ago but I think I remember that if you print out
to a plotter (HPGL) it does show the holes.

Thanks guys.



The previous incumbent had a special library of parts or so it

transpires...



I guess I'll have to find that!



best regards
