comment Issues using geographic and projected coordinate systems QGIS 2.0
The NAD83 ellipsoid is GRS80 and the WGS84 ellipsoid is WGS84, although close, they obviously differ. Many of the projects I work on have a stipulation of "Better than 2m" which requires me to use either the 14 parameter transformation or the more accurate NTV2 solution

Thanks Andre, I am currently working with QGIS 1.9 & QGIS 2 opened simultaneously. I've tried creating a custom CRS for OSGB36 but it is very time consuming when there are mulitple areas needing consideration.

I have been in discussion with the developer of the QGIS Transformation Tool Plugin and currently there is no intention of updating it unless funded and the cost exceeds anything that myself or my company could afford.

Having researched this and getting some advice, it would appear that (unless someone else can show a way) that the proj.4 method using nadgrids only works for points, for this there are much better tools out there. There is no documentation I can find which relates to transformation of polygon or polyline data.

This issue isn't specific to one particular data, this is an issue related to the geographic engine used by QGIS. This can be seen by bringing in any data of both WGS84 (epsg 4326) & OSGB36 (27700) or a combination of NAD83 & WGS84 in any format
