Perfect!  (well, most likely you will need a lateral support at at least 2 corners)

 

or spring supports..................

That´s not true.Forces on the inclined cables will produce horizontal forces on your structure. I would set the supports on the exact direction of the cables.Doing that you won´t need to add any other supports. For creating the " tricky" support ,create a new one fixing de X direction , then click on " direction" and give the coordinates of the point where the 4 cables will join.Then assign this support to your 4 lifting points.Check if they´re on the exact same direction of your cables.

Should all of the "fixed directions" be checked? Like on the pic?

Yes ,but it looks like the support directions are wrong, probabbly due to the fact you assigned a fixed support for them all

Perhaps this is true, but your method seems like a lot of hard work for not much gain.  But each to their own :smileyhappy:
