Line 4: \|alt_msg=NA \|type=[[ERROR]] \|message_desc=TUFLOW was unable to triangulate the polygon (region) object. The most likely reason for this to occur is that the region perimeter crosses or snaps onto itself. An example of a self-intersecting region is shown below with (the blue circles highlight the problem areas), click on image for a larger view.<br> [[File:Self Intersecting Polygon.png\|500px]] \|suggestions=Check region perimeter does not cross or snap onto itself. To help identify the problem, the ~~follow~~following steps can be used:<br> * Import the [[Check_Files_2d_sh_obj \|sh_obj]] check file. This file is written sequentially and the last entry is the final object TUFLOW was able to process. The final triangle is shown in red below:<br> <br> [[File:Error 2232 01.jpg\|600px]] <br><br> * This ~~highlights~~shows that the issue is in the 2d_zsh polygon ~~in the 2d_zsh~~ layer (highlighted in green): <br> [[File:Error 2232 02.jpg]] <br><br> Line 26: 307119.21 183875.86<br> </tt> * To remove this in QGIS, the layer needs to be made editable and "cleaned" with the v.clean tool from Processing Toolbox. * To remove this in MapInfo, the layer needs to be made editable and "cleaned" as per the images below.<br> [[File:Error 2232 03.jpg]] [[File:Error 2232 04.jpg]] <br> If the above doesn't ~~help~~fix the issue: Try adjusting the TIN angles. Use <font color="blue"><tt>TIN Angles </tt></font><font color="red"><tt>== </tt></font><font color="black"><tt>95,1</tt></font> command in the .tgc file before reading the TIN. Add more vertices in location of the last triangle from sh_obj_check file.
