There are problems with doing X and Y flips - they don't swap layers and
they leave components in upside-down. The L-Flip (layer flip) with
selections is also fraught.
What purpose does X Y flip serve with respect to the components themselves
apart from sorting out assembly layer issues for

The print preview has a little box that you can check to mirror the layer. I
just create a silkscreen layer with a mech outline and the silk screen you I

We are considering to build some prototype PCBs by isolation milling.
Has anybody got experience which software is suitable to generate HPGL- or DXF-Files
for the drilling machine from our Protel 99 SE
Gerber-Files?
Is there some free or cheap software available?
Thank you for all of your help!
Hi Florian,
I have used the Isolator software from T-Tech out of the US. It imports
gerber files and drill files directly then generates its own isolation route
files. It is very effective and easy to use, but not very fast. It's great
for single sided test PCBs but I found it a bit of a pain for
What type of driller?
Are you talking about just drilling the pads holes?
Or, are you talking about a board milling machine?
Usually, board milling machines will take the Gerber process it specifically for
the milling machine. As for a hole drilling machine, the 1 of the generated drill

Actually, when we used the Isolation S/W, it was for a New Hermes Vangard
7000 plotter/miller. It is usually used for sign making, but because it has
the variable speed armature in Z axis and accepts HPGL input, that's what we
used to iso-route PCBs. T-Tech has their own miller/plotter
Hi Brian,
we want to mill the whole PCB (drills + traces).
Our mechanics uses an ISEL milling machine for mechanic prototypes.
We want to use this machine also to manufacture our prototype PCBs.
Therefore we need a converter-software from Gerber- to HPGL- or DXF-Files.

how do you clean up the rough parts?

I didn't even know these guys existed. Good pricing. I've always used APC

I've had some luck in regenerating the complex curve by manually re-entering

Steve is right. There's definitely a problem with tracks that had a net,
and then had all attached pads removed, and updated via Update Free
Primitives from Component Pads. As you run the cursor over them, the
status bar still shows the old net. And even though the Properties dialog
shows No

this answer is colored by the fact that we don't actually do
assembly here.
First we typically use thin laminates 0.008 - 0.0031 with a
majority in the 0.020 - 0.025 range. Our tabs are just solid tabs, no
drills to allow easier breaks. Our tab width is typically about

Protel99SE + SP6 and W2K. DRC-report says that I have 12 violations

how that can be possible? I have manually checked all violations that have
