<p class="MsoNormal"><span lang="EN-US" style="font-size:10.0pt;font-family:"Arial","sans-serif"">I just opened a polygon table from my MS/SQL (2016) for editing. It loads without problems.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="font-size:10.0pt;font-family:"Arial","sans-serif""><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="font-size:10.0pt;font-family:"Arial","sans-serif"">I then did some node editing, only moving existing nodes. This was saved without problems.<o:p></o:p></span></p>

<p class="MsoNormal"><span lang="EN-US" style="font-size:10.0pt;font-family:"Arial","sans-serif"">I then tried to add a couple of new nodes, and then QGIS failed in committing the change !?!<o:p></o:p></span></p>

<p class="MsoNormal"><span lang="EN-US" style="font-size:10.0pt;font-family:"Arial","sans-serif"">I investigated the error, and it seems that (1) QGIS adds a random Z value (17) to my polygon nodes, and (2) inserts a Z value of “nan” on new nodes. Why???<o:p></o:p></span></p>

<p class="MsoNormal"><span lang="EN-US" style="font-size:10.0pt;font-family:"Arial","sans-serif"">Question 1: How do I force QGIS to not adding a dummy Z to my loaded polygon layer, i.e. work with it as a 2D geometry ?<o:p></o:p></span></p>

<p class="MsoNormal"><span lang="EN-US" style="font-size:10.0pt;font-family:"Arial","sans-serif"">Question 2: How do I force QGIS to insert a valid value e.g. a “0” for dummy Z values in all new nodes ?<o:p></o:p></span></p>

<p class="MsoNormal"><span lang="EN-US" style="font-size:10.0pt;font-family:"Arial","sans-serif"">Yes, I have created tables (or actually views) named “geometry_column” in the relevant schemas _<i>and</i>_ dbo, with a value of 2 for “coord_dimension”. QGIS
seems to disregard this setting.<o:p></o:p></span></p>
