I have four shear walls that make a core modeled in RAM SS. when I export the model into RAM concepts to design the mat foundation, an error pops up saying the wall is not connected to a slab. Since I am exporting out the second floor the footings are not transferred over? How would I go about modeling a mat foundation using the export data from RAM SS.
Thanks
Model a rectangular mat footing in the Modeler on the 2nd level plan (Layout - Foundations - Mat...). Make sure the perimeter of the mat encompasses all walls that need to be supported. Add a concrete deck/slab to the whole mat. Then rerun the analysis and export the Mat to Concept.
I created a mat under the wall core and opened it in concepts. I also have defined the soil properties under the footings. But now when I run it this error pops up. Do I need the somehow fix the Mat? Also is there any reference/ tutorials on modeling with uplift in RAM concepts.

when using auto stabilizing in the x and y direction, wont that affect the lateral loads and over turning uplift moment
I would not Auto-stabilize it. I would add edge supports and/or spring lateral stiffness (analogous to friction).
