<p>Hi Nyall,</p>
<p>nice that we agree on both ;-)</p>
<p>I will start collecting a wish-list on 3D and we can do a crowd funding to address selected issues. Or we could do another QGIS grant on 3D improvements.</p>

<br /> I agree that this is desirable. Geotechs will also very quickly be<br /> demanding this feature in order to visualise boreholes correctly!<br /> <br />

I<br /> can look down on the terrain and then rotate the whole model until I look<br /> sideway into the model, but than the rotation is blocked. I cannot rotate<br /> any further so that my camera gets below the surface and that I could move<br /> below the surface and look up towards the terrain. I guess this makes a lot<br /> of sense for people who do not need to explore things below the terrain<br /> surface, but for geologists or cavers, it would be great if this<br /> rotation/tilting blocking could be disabled somehow.</blockquote>
<br /> I'd suggest this should be an option in the 3d view configuration. I<br /> agree it's a valid use case, but for most users it may be unwanted.<br /> <br /> Nyall</div>
