Lander/rover subassembly woes

[Erebus]

Alright, so I'm having a tough time trying to figure out how I can get my lander/rover assembly put together and saved as a subassembly

Here is what I originally built and what I would like to attach, at the lander can, to my lifter:

The problem was that I started with the cockpit as my root piece and couldn't save it as a subassembly so I started with a docking port and built my rover, but then I would only be able to attach it vertically under the lander.

After giving up and starting over, I came to this

But I cant attach the next part horizontally onto the attachment point on the bottom

Is there a way I'm not seeing of how to do this? I don't care if the rover and lander are one or two assemblies.

[Mr.Rocket]

Make the rover as a separate subassembly, and have the root part be a docking port. Then, put one of those side attacher thingys ( what ever the thing that is currently under your docking port, forget what those are called) under the docking port, and build the rover from there. Then your can save it as a subassembly and the attachment point will be on the top of the rover.

For some reason it duplicated an image instead of posting the one where I attempted that.

Starting from a decoupler and a radial attachment you still cant connect the rover body horizontally to the attachment point which you can kind of see where I tried placing a fuel tank under the lander

[Mr.Rocket]

Did you try turning the part with wasd? or shift wasd for smaller?

I always use a Modular Girder Segment as my Root part for anything I want to turn into a sub-assembly. This gives me the proper orientation that I want to build in, and I can plop on a docking port (Or anything else for that matter) and I am guaranteed to have a free node. As for the radial attachment thing, you are going to need to point your camera straight up beneath the docking port. This is done by moving your craft to the top of the VAB, and rotating the camera such that it is looking up and zooming out a bit. Then place your part (It follows the mouse pointer) and you will notice that it clips through the port, at this point just use WASD to rotate it into place.

Thanks taki, the bit about looking straight up was all it took. Mission was successful, in part at least. Sort of a side question about science now though. I was under the impression that recovering the kerbal who performed the experiments was all it took to get credit, but apparently not. I sent my lander assembly from orbit, dropped my rover, touched down, got out and into the rover, drove around and did all my experiments, got back into the lander and met up with my orbiting command and returned it to kerbal. How come it didn't count any of my mun experiments?

Probably all the experiments were stored in the lander's pod, and you returned the orbiter's pod to Kerbin. When you EVA the kerbal to transfer him from the lander to the orbiter, right-click the lander's pod and choose "Take Experiments"; then he'll carry off all the experimental data stored in the lander's pod, and store them in the orbiter's pod when he boards it.

You'll also want to EVA and right-click-take the data from the various experiment parts, if you haven't done that already.
