https://communities.bentley.com/products/geotech-analysis/f/forum/244319/beam---plate-connectionHello everyone, I&#39;m trying to custom connections at both sides of a beam. At the bottom side, after creating interfaces the calculation works correctly. But at the top side, even with interfaces I still get the Invalid Connection Error.

This means that the custom connection cannot actually split any nodes using the interfaces, as there are no nodes at all.</p> <p>Can you try creating a dummy soil volume to cover the top part, too? And in Staged construction, you can&nbsp;simply deactivate it, as it is not needed apart from generating those nodes you need.</p><div style="clear:both;"></div>
