What are you using for your elevation reference?&nbsp; Are you actually identifying it or just using the &quot;active&quot; terrain?<br />2. Have you specified a vertical offset when placing the node?<br />3. Since you are apparently using the top of curb as your elevation reference, is the 3D cell you are using designed for that situation?&nbsp; Drop inlets would typically use bottom of curb elevation, so you may need to check the 3D &quot;top&quot; cell to determine where the insertion point is assumed to be.</p> <p>If none of the above clarify the issue, then I would send your data to Bentley with an SR so they can investigate the source of the problem.&nbsp; Good luck.</p><div style="clear:both;"></div>
