I am trying to mate several loc-line segemtns together and have the ability to position the assembled hole to diffrent positions. Each mate I try locks the part or give error. Attached picture and SLDASM file

Concentric between the internal and external 'balls' should do it. Depending on the size they have a range of motion, perhaps you could tie that to a spline using a user defined point at the pivot so as to follow the spline and the minimum curvature they also specify. You could create a situation where the motion, travel or position would exceed those manufacturer design limits. Though adding specific 'limits' to all the mates would make the assembly very finicky. Remember to define the assembly as 'flexible' too.
Concentric is invalid. I am a newbee and will need to learn spline, thank you for the info.

Can you attach the part file? I guess the internal cavity isn't spherical. You might be able to use tangent mates instead.

I am using SW10 and still cannot get the mates to work. Is it even possible to do in my version of solidworks ?
B.
The problem is that your part file is incomplete. It is just surfaces and does not include the internal socket for the ball part to mate with. You will need to fix the model and then you can mate it properly.
Edit the part and then do a section view through the center. Start a new sketch and complete the inside geometry as shown below.
Then do a Revolved Surface to complete the shape.
Then Kit Surfaces with the 2 surface bodies and check the box for "Try to form solid". Now you will be able to make a concentric mate between the ball of one segment with the socket of another.
I dont have enough experience with SW to compele the task. Thank you for your quick respose.

I found another part on 3D central that has the required cup. I has able to mate with tangent but the parts seperate. How can I keep the distance and retain the revolve aspect of the tangen mate ? Still learning SW so please bear with me.

Try to do a concentric mate instead of a tangent mate. Then it should keep the ball in the cup but allow rotation.
Thank you so much. Works great.
As Bernie said you should be able to so a concentric mate between the ball of one and the socket of the other. If you put an axis in the part you can put a Limit Angle mate to constrain the angle between two sections (0-30 degrees for example).
Also if/when you switch to SW2015 one option would be to model it with the new Chain feature, using a spline as the path.
Here's a quick video of just a concentric mate and two Loc-Line elements, this was done in SW 2012. If it doesn't show it is here: http://youtu.be/dKv0isFTqz4
I just added the assembly and part file.

Thank you for the posting but I am using V10 and cannot open file

Bobby,
You didn't send the part file with that assembly so I opened it in eDrawings. I sectioned the parts and there is no internal ball to mate too. Then again I'm not sure I can trust that model in eDrawings as I don't really use it.
If you want those parts to mate you'll have to provide a receptacle for that ball in the form of a revolved cut, they will then mate properly. I downloaded my model from 3D Content Central, the oldest version they have there is 2012.
Can you save the file so I can use on SW10 ? I have tried to mate but unsuccessful

Hi Bobby. I've followed this post and would like to way in on this.
It sounds to me like you want the assembly to move as it would in reality. So you could evaluate the limitation of movement in the loc line hose.
Is this correct?
Correct, for both example drawings and position options.
