Adding Joints/ Connecting Members (KARAMBA)

Hi everyone,

I am currently trying to analyse the attached structure using karamba. I have used a number of different surfaces from  rhino and plugged them into (assemble) component. Unfortunately when I visualise the deflections, my horizontal bracing is not connected to the column with a joint. Why would this happen - when these elements where taken from individual curves in between columns in rhino? and how can I arrange this?

I also cannot understand how to alter the joint between the roof truss and the columns as i would like to have one end of the roof pinned (at cantilever) and the other a roller. All supports under the columns seem to be fixed in all directions - I tried using Beam-Joint and Beam-Joint-Agent but it doesnt seem to have solved the problem!

Thanks in advance!
