How to find the most critical service load case for the soil bearing and obtain a bearing pressure plot for that case ?
The Calculation Sheet reports the worst service case for bearing pressure as can be seen from the picture below
Once you know the critical load combination number, you can plot the bearing pressure corresponding to that case following the process outlined in the wiki below

The Current Load can be selected from the combo box in the ribbon menu at the top as shown next
