Is there a way that Prosteel can read/import a Tekla file? If yes, does anybody knows the procedure/steps?
Well, there are some ways, either with ISM, they need to create a repository and you read in the ISM via new from repository. for this you need the structural synchronizer.
For the version of Structural Synchronizer needed see for example
http://communities.bentley.com/products/structural/drafting___detailing/f/343337/p/115468/354236#354236
or they export as SDNF or CIS2/Cimsteel and you read in via import.
ISM has update capacity, see also in YouTube Bentley Structural channel
