Dear Cecil, I've posted this message once but it seems to have disappeared. Probably, I did it the wrong way. So I am trying again. From your Cecil's method of finding the Main Entrance compass direction, I am very confused and need your advise and clarification. 1) Standing in the middle of the house - How should I find the centre of the house if my house is a figure of short, fat diamond 8 shape ?? - Should I just join the 4 most outer corners of the house to get the centre ?? 2) With method 1, the animation standing in the middle of the house searching for the 90, 270, 0 & 180 degree and direction of the main door. - Does the 90, 270, 0 & 180 degree represent the North, South, East & West direction respectively ?? Does it mean that the red arrow in the compass pointing at the North is 90 degree, South is 270 degree, East is 0 degree & West is 180 degree ?? - Am I right that after finding the direction N,S,E & W, we imposed them on the floor plan to find the direction of the Main Entrance, or we must use the compass direction degree to find it as a guide ?? 3) When using the protractor, I realised that protractor 0 degree is aligned with the initial 180 degree ( I presume that is the West compass direction). - Am I seeing it right ?? Shouldn't it be 33 degree if initial 90 degree (to be align with protraction 0 degree) is the North or 303 degree if initial 0 degree is align with protractor 0 degree or 213 degree if initial 270 degree is aligned ?? Sorry I am not doubting you but I am just confused and just need your explanation. - If 123 degree is right, then initial 180 degree is the compass North Direction and it is then 123 degree to the Compass North, that is South-East facing or with initial 90 degree being the North, it is North-East Facing ?? 4) Method 2, the animation standing outside the house. - Can we stand just inside the main entrance to do it ?? - With first pointing 0 to 180 degree, does it mean that the compass red arrow is pointing West direction or the East direction ?? - And then with next pointing 90 to 0 degree, the compass red arrow should then point to what direction ?? Basically, I am confused with method 2. Please advise. I am sorry for such a long message. Thank for your time and patience. Your advise will be very much appreciated. Regards
