Why gives Export to CAD with Projection in environment different results to Project shape and the export to CAD?

[TheDLH]

Hello,

I do have a *.shp in EPSG 25832. I ahve tried tow scenarios transform this to *.dwg in EPSG 31468:

1. Project shapefile and then export this to CAD

2. Export shapefile to CAD while setting 31468 as target CRS in the environment of the Export to CAD function.

1. Gives a correct *.dwg

2. Gives a *.dwg with a location shifted about 150 m to the soutwest.

Why is there a difference? It would be nice to have the second option as this is less work.

thanks,

TheDLH

When you project the shapefile, does the tool set a geographic/datum transformation? Export to CAD probably isn't and it doesn't look like it supports the geoprocessing environment for setting a default transformation. You could try that anyway--use the same transformation as the Project tool and see if it gives you the correct result.
