<table cellspacing="0" cellpadding="0" border="0" ><tr><td valign="top" style="font: inherit;">Dear Gmsh users,<br><br>I'll rephrase my previous question, as it may have been unclear:<br><br>Gmsh creates a bounding box (BB) enclosing all shapes. It is possible to display the coordinates of this BB (upper-left and lower-right points) via the GUI.<br><br>However. is it possible to assign these coordinates to user-defined variables?. For example:<br>a[] will hold the x,y,z coordinates of the upper-left BB point and b[] will hold the coordinates of the BB lower right point?.<br><br>Thanks,<br>Mike.<br></td></tr></table><br>
