Custom Footprint Fields Reset when Saving to Lib.

   Ryan - in a normal world, you download an FPX file from "Parts on Demand" or manually enter all the component dimensions and attributes yourself, fine tune all your rules and build the library part. 
The FPX data then becomes your Search Engine to quickly locate footprint names and access datasheets. 
I have never needed to build a part more than once. However, we do have Batch Create to apply an large FPX file with component dimensions with personal rules. 
The original question was do you mix Least, Nominal and Most environments in a single FPX file and the answer is FPX does not save environment data. The Library Expert allows you to auto-generate a complete PCB library with the Least Environment and then create another library with the Nominal Environment or create another library for Wave Solder and another for Flexible Boards or a specific assembly shop. You can create a thousand different libraries with the same FPX file.

	Tom, Yes, but I may never want wave solder library entries for 0402 resistors, for example. I could surely have 3 different environment configurations, but each of those may only be applicable to some subset of my FPX file. I don't want extra library entries for components that are untenable. To what extent can Batch Create apply personal rules to the generation of libs from the FPX file? Ryan R.

	The FPX file can save your Footprint data in the FPX file in both the calculator and FP Designer. When using the Calculator, select the Footprint Tab and then select "Use Mfr. Recommended Pattern" check box. You can leave the IPC-7351 calculated data in the fields or enter your modifications, then save to FPX. Then you can Batch Create your large FPX file and the program will always use your settings. Or you can create your parts in FP Designer and customize them there and save to FPX. Then whenever you Batch Create your FPX file it will always use your personal pad stacks and drafting outlines.
