I want to use ARIS to drow DFD ?
Dear Mohanad,
Data Flow Diagram is one of 150+ model types in the commercial ARIS product, not ARIS Express.
In ARIS 7.x and ARIS 9.x you will find in the document "ARIS Method" details which object/connection/symbol types are allowed in that model type.
Does that help?
Cheers
Rune
