You have an analysis model. You have a BIM model. Probably they are sync together. Once the structure has been designed, you can use braced.io to solve your connections in three steps:
Get your forces from your analysis model (manually for now).
Solve connections in our web application & download reports for your calculation notes.
Automatically build connections in your BIM models with our plugins (no files, no data input).
As a result, you get the engineering documentation and the connections completely executed in Tekla.
There are several builtins: materials (S275, S355, ...), profiles (HEB, IPE, UPE, Pipes, Tubes, ...), bolts (Metric, Imperial), etc.
These are the most used items in Europe. You can use them or you can create custom items. Everything is managed from the Materials tab.
First you have to create a team with your mates. Every connection solved will be stored in the database. We store connections by organizing them in projects and structures. So a team has projects, a project has structures, and a structure has connections.
