+Extrude 2D vector to 3D vector:
+ * Go in the layer manager canvas to "Vector" -> "Develop vector map" -> "Extrude 3D vector map".
+ * Have the "house" vector map selected, insert "house3d" as new 3D map (Required tab)
+ * Go to "Optional" tab and activate "Trace elevation" to make the house bottom line follow the terrain and select "elev_lid792_1m@PERMANENT" as "Elevation map", then "Run". This creates the 3D house vector block.
