Is there a way to convert 2D features to "3D" features in QGIS? I know there is a way to do this in ArcMap by using an attribute value in the attribute table, but I am looking to do this with shapefiles in QGIS.

I want to convert to 3D from 2D – user39281 Oct 16 '14 at 11:15
Convert what? Lines, polygons, points? – Ryan Garnett Oct 17 '14 at 1:04

You can use the module in the GRASS toolkit (installed with QGIS) to do 2d to 3d layer transformation.

Thank you, this seems to be the exact tool, however, when I look for the tool in the GRASS Tools I do not see it. There are four tools available (r.topidx, vdrape, v.random and nviz) when filtered by 3D, but no I am new to Grass Tools, is there something I am doing incorrectly? – Ryan Garnett Jun 21 '12 at 16:08
The module is new to version 6.4.0, see link – artwork21 Jun 21 '12 at 16:28
I have downloaded and installed the newest version of Grass (6.4.1-1). After installation I do not see the tool available within QGIS. What am I missing? – Ryan Garnett Jun 21 '12 at 17:12
