<body><div>I have data on environmental parameters at varying depth intervals. For each polygon of area, I duped the polygon data layer into multiple data layers, with each data layer having a single depth-specific record (I would ideally like to do it as the poster was asking about in this thread - <a href="http://osgeo-org.1560.x6.nabble.com/automate-v-extrude-from-a-table-td4978722.html#a4978730">http://osgeo-org.1560.x6.nabble.com/automate-v-extrude-from-a-table-td4978722.html#a4978730</a> but there seemed to be no easy way to do this other than some complex python scripting, so I separated/duped each polygon by hand and then all the records except for the one corresponding to that depth interval, before it got extruded).<br></div>
<div> </div>
<div>I then ran v.extrude to generate the volume corresponding to each separate data layer. However, the resulting 3d data layer does not appear to have an attribute table. <br></div>
<div> </div>
<div>Does v.extrude not "bring along" the attribute table or am I doing something wrong?<br></div>
<div> </div>
<div>I need the attribute table info, since I plan to merge these separate extruded data layers into a single data layer and then query them based on the a field value and then visualize the results in nviz. However, if the attribute table doesn't follow into the extruded shape, then I can't query.<br></div>
