I'm building a theatre in Capture where they have a permanent installation of truss arches following the building structure. It's not truss that can be assembled/disassembled... The angles are odd, and all the joints are welded.

I'm using Prolyte Astralite to build these arches as the triangular section dimensions are correct. The problem is that the sections in the theatre aren't standard lengths (as it's been made to fit the building).

Is there a way to 'unlock' the truss sections from the library so I can make them the odd lengths that I need?

Thanks
