<p class="MsoNormal"><span lang="EN-US" style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">The reason why I need to do that operation AFTER having defined the volume is that I have an automatic procedure which reads a geo file, perform
a translation/rotation on one geometry component specified through its physical surfaces IDs, generates the mesh and carry out the simulation . This is done in an outer loop so that many geometry modifications are analysed in the same run. For this reason
the procedure appends the commands at the end of the geo file.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">I guess the problem is related with the use of OpenCascade, because the same approach works fine in cases when the Built-In geometry kernel is

Hullo everybody. In the last two lines of the attached geo file I retrieve the list of elementary surfaces ID from their physical IDs, and then apply a rotation to the list. However, only the edges are rotated, and the "old" surfaces and edges are not deleted
after the operation. Why...? Thank you.<br>
