    <p>How would I buffer an IPoint to do an intersection check using IRelationalOperator?</p> <p>I have, for arguments sake:</p> <pre><code>IPoint p1 = xxx; IPoint p2 = yyy; IRelationalOperator rel1 = (IRelationalOperator)p1; if (rel.Intersects (p2)) // Do something </code></pre> <p>But now I want to add a tolerance to my check, so I assume the right way to do that is by either buffering p1 or p2. Right? How do I add such a buffer?</p> <p>Note: the Intersects method I am using is an extension method I wrote to simplify my code. Here it is:</p> <pre><code>/// &lt;summary&gt; /// Returns true if the IGeometry is intersected. /// This method negates the Disjoint method. /// &lt;/summary&gt; /// &lt;param name="relOp"&gt;The rel op.&lt;/param&gt; /// &lt;param name="other"&gt;The other.&lt;/param&gt; /// &lt;returns&gt;&lt;/returns&gt; public static bool Intersects ( this IRelationalOperator relOp, IGeometry other) { return (!relOp.Disjoint (other)); } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
