INTEROPERABILITY
1- A (REVIT) TO SE (ETABS)

1. IMPORT CAD CENTERLINE TO SAP
2. FIX OFFSET VALUES IN JOINTS (BEAM-COLUMN,
   COLUMN-COLUMN, BRACES)
3. DIVIDE COLUMNS TO SEPARATE FLOORS
4. JOIN CURVED ELEMENTS TO BECOME ONE MEMBER
5. EXPORT FROM SAP TO ETABS

FUTURE?
Tekla
SAP
2-way direct link

• Use Tekla direct link to SAP
• Develop the analysis model inside Tekla
• Export the model to SAP (ready-to-run)
• Run the analysis
• Design members
• Import members back to Tekla and update the model
