I’ve had plenty of experience learning software & drafting programs,
but <st1:stockticker w:st="on">IES</st1:stockticker>’s VE is very
different from anything I’ve used before or since.  I think it’s
getting easier with the updated help section, but sometimes hunting for
something specific was painful.  Drawing complex 3D curves is difficult,
but we have managed to get great quality pictures and fly thrus.  <o:p></o:p></span></font></p>
