That is my point if your customer generated the gerbers then they have a CAD
database. Why not just give you that database? Seems strange. There is a
better chance converting on CAD database to another than trying to create a
CAD database from post processed data.

Hi,

Any body having Experience in Conversion from Cam350 to  powerpcb and
powerpcb to allegro

 I have Tried by following steps.

Cam 350

1.imported Gerber's and build a part also I have extracted the net list.
2.Exported the gerber as .ASC format in powerpcb ver2.0

Powerpcb

1.Imported the .ASC file in to Powerpcb

2.Again I have exported as .ASC format.

Allegro

1.Imported .asc file(which i have exported from pads) in to allegro by using
file /Import/PADS/  option.

The time of conversion allegro shows error and it closing.(pls find attached
the viewlog file)

I opened the board file which is created in allegro, I am missing the
Traces.

Components are coming.

line,Board outline  is coming in allegro.

But traces are not coming in to allegro.

Doubts

1.Why the traces are not importing in to allegro

2.Also Allegro is not taking directly the .ASC exported from CAM350.Allegro
is accepting only the .asc  file which exported only  from powerpcb. Why ?

3.Pls Explain the step by step flow for this conversion.

Thanks in advance.
