This add-on directly integrates Solibri Model Checker and ArchiCAD. The building model is transferred from ArchiCAD to Solibri Model Checker with only one click. The exported models can be checked against several requirements in Solibri Model Checker. During analysis Solibri Model Checker automatically assigns severity classification to all design issues found. The identified design problems are directly sent back to ArchiCAD for clarification and fixing. The work flow is smooth, easy and productive.
