When i try to enter the second one in a surface, the program gives me a message to link this one to the other lower vertice of the surface. This means that i just can have 2 windows per surface? So i must put an equivalent window area (to that 5 or more) in the surface? Or can i link more than one window to the same lower vertices? If i do this, ESP-r will have fatal errors? </FONT></DIV> <DIV><FONT face=Arial size=2></FONT> </DIV> <DIV><FONT face=Arial size=2>Sorry to make this questions, but the "Cookbook" don't refer this...</FONT></DIV> <DIV><FONT face=Arial size=2></FONT> </DIV> <DIV><FONT face=Arial size=2>I would apprecciate any kind of help, before made any mistake that will lead me to a long time of corrections!</FONT></DIV> <DIV><FONT face=Arial size=2></FONT> </DIV> <DIV><FONT face=Arial size=2>Regards,</FONT></DIV> <DIV><FONT face=Arial size=2></FONT> </DIV> <DIV><FONT face=Arial size=2>Paulo Tavares</FONT></DIV></BODY></HTML>
