[Qgis-user] import 3D line into a shapefile?

[mtnbiketrail at zzz.com]

Hi, I'm a beginner user.
Is it possible to import a 3D line into QGIS? I have the text file with 
distance, compass, and azimuth and want to have it show as a 
shapefile(?) in 3 dimensions inside QGIS.  How would I go about doing 
that? Also, correct me, don't I have to use the correct datum to show 
3d. Like WGS84? I don't think NAD83 can handle 3D?

thanks,
Tom
