What is the significance of spring angle?en-USTelligent Community 12https://communities.bentley.com/thread/478658?ContentTypeID=1Tue, 28 Aug 2018 20:46:18 GMT6dad98f5-dbc9-4c4d-a9ba-e9da8dc6aa8e:c6bd0fe9-51e0-49b9-ba07-5114008edc0fSeth Guthrie<p>An&nbsp;area spring has an orientation. The default is 0 degrees, so the R axis runs left to right and the S axis runs north to south on screen. The spring then has an R and S axis resistance that relate to the area spring local axis. Most soils&nbsp;are linear in the two directions, so I seldom see anything but 0 angle area springs with equal R and S resistance.&nbsp;</p><div style="clear:both;"></div>
