>>My room volume calc. is coming out as a negative number,
>>so are my Rt60 calc.'s., is there a way to correct.
>That is because your room is *inside out*, all the faces are pointing the wrong way round. Select a face, press *I* to invert the face, then press *H* to open the *Check Holes* window. Tell it to Check Holes, and this should fix the probem by turning all the other faces around to match the one you started with.
>Hope this helps,
Just a syntax note, you need to click on *Close Holes* to have EASE properly orientate the faces.Best regards,
