Dear Sir,

Is it possible in Prepomax modeling to implement the combination of Mesh + Stick model. The stick model in red shown in the snapshot purpose is load distributor.

Thank you for your kind support.  
Best regards,

Currently, PrePoMax supports rigid body constraints that can transfer loads from a reference point to nodes of the model. However, they introduce rigidity to the model. CalculiX also supports kinematic and distributing coupling constraints that transfer loads in more flexible way. They aren’t available in PrePoMax yet so you would have to use the Keyword Editor to add them: [RBE3 integration in PrepoMax (Kinematic & Distributing Coupling)](https://prepomax.discourse.group/t/rbe3-integration-in-prepomax-kinematic-distributing-coupling/44). They have some limitations too and have to be used carefully.

Dear Sir,  
Thank you so much for sending more detail information. I would love to try and explore on this.
