I always found it fascinating that the CAD tools I use for large scale
subjects (ie facilities, plant wiring) had better resolution and tools for
accurate drawing than the stuff I use to design fidget sized 10mil pitch
projects
I also liked the fact that ACAD can draw a 2D drawing of the so
International Rectifier has some app notes on it (AN-1012 comes to mind)...

I think you're seeing an issue I brought up to Simon (the founder of
camtastic) back before he was bought by Protel.
What happened to me was the fills on my PCB were coming in with "x"'s from
corner to corner. I found out that it was turning my fills into components
(camtastic has this feature
Yea, I have some issues with camtastic as a CAM tool. I agree that a board
fab would not use it since it does have some limitations.
It needs to handle merging drill and gerber data from different designs a bit
better. The naming gets weird and the drills never merge quite right...
It also ne
I did this last year when I realized the limitations of Camtastic in merging
separate PCB's.
I had to have separate PCBs, since the front panel controls (switches, rotary
encoder, display) are all different stand off heights. I used the 1mm flex to
interconnect.
What I did was to segregate th
Nice patterns! thanks...
Also, don't forget convergence patterns. I have one that's the typical white
crosshatch/dots on a black background I can send for you to post. If needed,
I can make it a PDF...

Yea, most of the cheap cards I see are not PCI compliant. We have a cheap vid
card that works OK in 32/33 but in a 66Mhz slot it gets a bit weird...even
though the PCI interface is rated for 66Mhz.
If you've ever looked the PCI clock and signals on an active slot you'll see
why the spec is imp
The way I generate tabbed panels with mouse bites is a combination of ACAD
and Camtastic. I have a Protel lib part thats the layer info and NPTH holes
for snapping to the imported DXF in Camtastic. I keep the spacing of the
mouse bites consistant and copy them to the DXF arc centers in groups.

I've seen this happen with both Multilayer and top only SMD...just happened

Best way to find it is to look at the report (menu - Reports - Board
Information - then generate the report by setting to all). You'll see a
heading for non-plated hole sizes like so:
