How Can We create box section of 2ISMC with 4mm gap? I have thought of two methods
1. Create profile in AutoCAD and use 'Define cross section using DWG file'.
2. Add 2ISMC and create weld between them in tekla although there is gap, it will be treated as assembly.
Which of the two method is good one?
I do face some problems in connections while connecting box channel beam to this colum.
Any other methods, suggestions?
