Hi,Thanks to Arno's Bumpy tool I am trying to generate a SCA file to harden the surface of my photogrid. However there is one detail that I have in my original photogrid code and that is the TransformCall command that shifts the grid in the sea nad brings it back on land therefore avoiding autogen exclusion. So my quest now is to make the SCA generated by Bumpy includes the same extra code as the original photogrid so the hardening of the surface will match the shifting of the photogrid.I tried to copy the Variables section from my original SCA into the Bumpy one but while compiling it with FreeSC (FSC) and scasm too, I got errors. Here is the SCA generated by Bumpy and followed by the original one with the portion code of the photogrid :Header( 1 35:29:5.942381 32:09:6.057058 37:29:33.202709 33:29:14.797966 )LatRange(

Maybe not the solution you are looking for, but why not calculate the answers of the calculations (DX, DY, etc) and then just hardcode them into the commands? Then it should work.Arno
