I finished reading this entire thread

and also reviewed the tutorials on post #1. Most of the information is about using tracks or sonar recordings but, in my case, I'm using the AutoChart Live recordings I've created for my 10,000 home lake. I now have the AutoChart Pro software and have made a first pass at importing the AutoChart Live .acu files from my original Zero Lines card and creating the new LakeMaster chart on the new ZeroLines Card. I have attached a screen shot of the import process with one section created.
Based on this initial pass, I have a few questions:
1) It successfully imported all of my AutoChart Live recordings (see attached picture) but the "Create Map" process only mapped a very small "chunk" of my recordings. Is this correct and, if so, am I going to have to do the whole lake in little chunks or is there a more streamlined way to do it? In the picture, you will see the small "chunk" that was created in the middle of the picture.
2) The Humminbird ZeroLines card doesn't have a good shoreline reference for my lake (Tims Ford Lake in South Central TN)... It's missing two entire large fingers of the lake. On my ZeroLines Card I use with AutoChart Live, I have imported the shoreline reference from the Humminbird ChartSelect LiveShare site. It has a much better shoreline for the lake. On my Solix, I select that as my shoreline reference for AutoChart Live rather than the default one from the ZeroLines Card. Can I use that ChartSelect LiveShare Shoreline Reference in the AutoChart Pro software as the base map? If so, how would I do that?
I'm sure I'll have more questions down the road but that should get me started.
