Area Loads defined in Revit are transferred to RISA 3D and RISAFloor as Area Loads Note e Revit Area Loads which are defined by more than 4 points are ignored by the Link when transferring to RISA 3D e Each Revit Area Load is given its own Area Load definition within RISAFloor Identical area loads are lumped into one Definition e Revit only allows one load case per load Therefore when importing RISAFloor into Revit only one load magnitude will be transferred from a given Area Load Definition The load chosen will be the first encoun tered in the following order LL DL OL1 etc Load Cases Categories Load Cases and Categories are mapped between RISA and Revit using the Mapping File Load Combinations The transfer of Load Combinations between RISA and Revit is limited due to inherent differences in how the pro grams handle them Note e The State flag within Revit maps to the Service flag within RISA 3D e The Type flag within Revit maps to the Solve flag within RISA 3D e RISA 3D only supports load combination nesting up to one level deep Any further nesting will be ignored by the Link General Reference Manual 27 Appendix B Mapping Files RISA and Revit use different terminologies for Shape Names Material Names and Load Categories These ter minologies are linked to each other by a process of Mapping Mapping is done using a Mapping file designed to be customized per your standards The Excel based XM

8. model is to represent the analytical model as accurately as possible There are many circumstances where physical arrangements are better represented in different ways from each other A Revit model may have a very complex physical arrangement that can be greatly simplified for structural anal ysis By starting in Revit you can model these physical complexities and assign an analytical arrangement for RISA to use If you instead start in RISA the link will create members in Revit but it will create them with the most basic physical geometry since it does not know your intentions for details Take the detail shown below for example On the left is the Revit representation of a column and beam On the right is the RISA representation The connection details shown in Revit are necessary for construction drawings however in RISA a simple fixed connection is sufficient to give an accurate analysis AL Nf Ft f A proficient Revit user can assemble a structure in Revit as fast as a proficient RISA user can assemble a struc ture in RISA Therefore especially if the architect has already created a model it may be fastest to generate a model first in Revit Structure which uses the architect s model as a template Starting in RISAFloor This is the second most common workflow RISAFloor and Revit are very similar in their scope in that they are both designed around building type structures which have floors roofs and
