I have been away from ObjectArx for several years now and it seems that some things have changed a bit.
I have an existing software package that I developed for A2k-A2k7 but it no longer works correctly in newer versions. I've been tasked with doing a complete core rebuild to make it fully compatible with AutoCAD 2014 though AutoCAD 2016 and hopefully beyond.
Once upon a time, I would build a version independent Arx and it would work correctly for the product cycle so far as the drawing version was concerned. i.e. the same arx could be used in A2k, A2k2, then A2k4 could be used in A2k4, A2k6 and A2k7 ....
Does that still hold true now? Also, I see the SDK now required VS12 for 2015-2016 and optional VS12 for 2014.
I'd still need to upgrade from VS10 to VS12.
Any tips would be greatly appreciated.
