https://communities.bentley.com/products/ram-staad/f/ram-staad-forum/243668/selective-selftweight---modeling-masonry-and-hollow-coreHello, In STAAD, is there a way to only have selfweight determined for certain plates instead of all in the model? Also, any insight on how, if I can, can I model 8&quot; masonry and 8&quot; hollow core with 2&quot; topping as walls and floors? Thank you,en-USTelligent Community 12https://communities.bentley.com/thread/760373?ContentTypeID=1Mon, 03 Apr 2023 09:18:33 GMT6dad98f5-dbc9-4c4d-a9ba-e9da8dc6aa8e:b2fc18a5-55fd-43b3-9c91-bb59ff4456ceModestas<p>Selfweight command can be assigned to specific plate numbers, it is not necessary to assign it to all plates or members.<br /><br />Can you show us some sketch on what exactly are you trying to model?</p><div style="clear:both;"></div>
