 Please check out the &amp;quot;O&amp;quot; in the attached DGN. I was hoping to just create a region to with a flood fill between the inner O and the Outer O but I am getting a &amp;quot;objects are not coplanar&amp;quot; error. 
 
 This is a 2D file so this shouldn&amp;#39;t be an issue</description><dc:language>en-US</dc:language><generator>Telligent Community 12</generator><item><title>RE: Non-Coplanar objects in 2D file</title><link>https://communities.bentley.com/thread/322162?ContentTypeID=1</link><pubDate>Mon, 27 Apr 2015 17:41:04 GMT</pubDate><guid isPermaLink="false">6dad98f5-dbc9-4c4d-a9ba-e9da8dc6aa8e:67b5739b-1d63-4676-802c-347694566e8c</guid><dc:creator>George A.

&lt;p&gt;&lt;span style="font-size:12px;"&gt;Hi Tom! Sorry this was not a quick reply!&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;span style="font-size:12px;"&gt;As Jon stated, the DGN is a container of 2D and 3D models. When you open M-Sta. and Preview the file, it will state whether the Default model (called &amp;quot;Model&amp;quot; in your file) is 2D or 3D. &amp;nbsp;You actually have 3 - 3D models (Layout1, Layout2 &amp;amp; Model) and one 2D Model (fishpond). Layout1 &amp;amp; Layout2 appear as 2D because they are Sheet models but if switched to Design models they are 3D.&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;a href="/cfs-file/__key/communityserver-discussions-components-files/273/Model2D_2D00_3D.jpg"&gt;&lt;img src="/resized-image/__size/940x0/__key/communityserver-discussions-components-files/273/Model2D_2D00_3D.jpg" alt=" " /&gt;&lt;/a&gt;&lt;/p&gt;
&lt;p&gt;All that said, I don&amp;#39;t think your problem is 2D vs 3D even though you got the co-planar statement but the elements that make-up the &amp;quot;O&amp;quot;. Both the outer and inner elements are single b-spline curves. There is something about both of those b-spline curve definitions that is causing the problem. I was able to use the Create Region by Flood on 2 b-spline curves I created, without a problem. re defining the b-splines would be the quickest solution.&lt;/p&gt;
&lt;p&gt;There are other ways to get the same effect but seems you figured one out. Another option is to use the Break by Drag Line across both b-splines and then join the 2 parts of the b-spline together into a Complex Shape for both Outer and Inner loops then use the Difference in the Create region tool. &amp;nbsp;&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Non-Coplanar objects in 2D file</title><link>https://communities.bentley.com/thread/322117?ContentTypeID=1</link><pubDate>Mon, 27 Apr 2015 14:10:42 GMT</pubDate><guid isPermaLink="false">6dad98f5-dbc9-4c4d-a9ba-e9da8dc6aa8e:3ff94b73-4be3-4a25-be36-3c6f89caf3ac</guid><dc:creator>Brien Bastings</dc:creator><description>You can use the Group Holes tool. Identify the 2 complex shapes by their edge as the tool doesn&amp;#39;t like interior picks.&lt;br /&gt;
&lt;br /&gt;
Both the Region tool and Group Holes tool should work better in MicroStation Connect...but I didn&amp;#39;t have a chance to verify yet.&lt;br /&gt;

&lt;p&gt;Since the launch of V8, there has been no such thing as a 2D or 3D DGN file.&amp;nbsp; A DGN file has no dimension.&amp;nbsp; A DGN&amp;nbsp; file is a container for one or more models.&amp;nbsp; A model may be 2D or 3D.&amp;nbsp; A DGN file can contain a mix of 2D and 3D models.&lt;/p&gt;
&lt;p&gt;In your case, &lt;span style="font-family:courier new,courier;"&gt;Fishpond.DGN&lt;/span&gt;&amp;nbsp; contains four models.&amp;nbsp; The model named &lt;em&gt;Model&lt;/em&gt; is 3D, and appears to be the default.&amp;nbsp; The other three models are 2D.&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Non-Coplanar objects in 2D file</title><link>https://communities.bentley.com/thread/322016?ContentTypeID=1</link><pubDate>Fri, 24 Apr 2015 19:06:11 GMT</pubDate><guid isPermaLink="false">6dad98f5-dbc9-4c4d-a9ba-e9da8dc6aa8e:ff16264a-3be2-4c08-bb3e-6a3cc3843125</guid><dc:creator>Tamicca Sellars</dc:creator><description>Thomas, &lt;br /&gt;
