(OP)
how do you create a spline from two or more points but you want it to end on an exsisting spline.
I.E, the dots are the points and the explamation mark is a vertical curved spline,

its just a point at which the spline will end at

It would also help to know which version of UG....as I believe some minor menu changes occured for Studio Spline between NX2 & NX3. At least UGS was thinking about incorporating the newer Studio Spline as the 'main' spline creation method versus the old Spline command.

I would use the old Spline command, then pick Through Points. Turn on single segment & then use point constructor & pick the 2 points followed by the end of the "vertical" spline....IF you don't require a tangent transition into the "vertical" spline.

What is mean by tangent transition
RE: Spline
I cannot stress enough that reading the documentation will help you out with these definitions. It's lengthy, but will be well worth your time in the long run.
You also may want to get a UG CAST license, which has basic courses that will help new users get introduced to common modeling tasks & techniques using UG. Call your sales rep for information & pricing. It's fairly reasonable but doesn't offer high-end modeling solutions (in my opinion).

Im not sure im building it in a correct way, but its built from surfaces. I am now trying to add the very rounded tip of the cone, how is best to do this??? and also, Im a bit worried that where the two surfaces (as the nose is made in two) meet at the side, that its not smooth??
RE: Spline
Select the Spline icon.
From the Spline dialog, select Through Points.
From the Spline Through Points dialog under Curve Type, select Single Segment & then OK.
At the next dialog, you will prompted for the spline point creation method. Choose Point Constructor.
From the Point Constructor dialog, select the Point icon.
Now, select the left-most point followed by the right-most point. DO NOT HIT OK YET! With the Point Constructor dialog still showing, select the End Point icon & then select the end point of the 'vertical' spline then select OK.
The Specify Points dialog pops up & you want to select Yes & your spline should show up & pass through the 3 points you defined.
If this doesn't do the trick, then you haven't told us enough information or you need to be more descriptive of the existing geometry.

Does v18 have N-Sided surface? If so, that will be your best bet. If not, then you'll have to create a mesh of curves & use through curve mesh in the freeform modeling application.

If this doesn't make sense to you, then I'd strongly suggest reading the documentation & getting some training. For me, it would have been easier to do the part myself & send it to you at this point in time.

RE: Spline
Where would it be under about surfacing....sorry to be such a noob, its just very daunting when you first start up :(

RE: Spline
i saw the part you are trying to make, you are making your life too difficult! for a part like that is not good using surfaces, and if you add the cone you want to make, you are talking about expert skills.
i would advice you to spend the time trying a solid and start making blends. you may use surfaces to cut it and shape it, but remember to use them only when necessary.
