Dear all,

In order to export a 3D steel model from Fastrak Building Designer (CSC) to Advance Steel, you need to do the following:

- in Fastrak Building Designer, export your 3D model to a SDNF file

- the generated file gets the .sdf file name extension => rename it to .sdnf file name extension

- in Advance Steel, click "Import SDNF" icon and select the renamed file

=> the 3D model is correctly imported into Advance Steel, and you can use e.g. the automatic connections from the AS "Connection vault" to connect beams together.

Best regards

Philippe
