I have found that this works with most gerber file formats.

Gerber to Protel conversion.

Sample of Lavenir Gerber File

D13*X1305Y1213D2*X1225Y1293D1*X1172Y1346*X1305Y1213D2*X1411D1*X1225Y1293D2*X1172Y1346D1*Y1452*Y1346*Y1452D2*

To Convert this to a gerber format that protel will recognise a D1 mus be placed next to each * where the * appears after a co-ordinate reference and there is not already a D1,D2 or D3.

Procedure

1. Open the gerber file in Wordpad.
2. Search and replace all * with D1*.
3. Search and replace all D1D1* with D1*.
4. Search and replace all D2D1* with D2*.
5. Search and replace all D3D1* with D3*.
6. Search for all D-code identifiers (ie. D10, D11 etc. ) and remove the D1 that directly follows them.
7. Repeat the process for all required gerber layers.

*NB Unless there are some special features in the soldermasks it is not necessary to convert them as Protel will generate its own masks.

Importing into Protel.

1. Open a blank PCB file in Protel.
2. Select File/Import/Gerber Batch and select one of the modified gerber layers when prompted.
3. Save the PCB file.
