The first is caused by the way ClearView loads bitmaps and thesecond by the different way in which FMS and ClearView use coordinates. The colours are strange and any writing ismirrored. If you were to try looking at your conversion in ClearView at this pointyou would notice two things. If it does get longer than that is the correct way round. A tip here is either to make the surface one sided so you can seemissing surfaces or just flip the 'normal' for a surface and see if it getslonger. This meansfrom the top you are actually seeing the 'normal' for the lower surface andvice-versa. Sometimes it can be difficult to see wrong 'normals'because the top and bottom surface of a wing can both be inverted. To fix a bad 'normal' select the surface (use surface mode) as in theillustration then chose surface->flip normal to make it correct. Although thismodel doesn't have a problem with inverted 'normals' one has been purposelyinverted in the picture below to show the effect. Generally this is wrong and in ClearView usually makes thatparticular surface black or very dark. The length can bechanged in the settings menu (file->settings) under the appearance tab.Change "Size of display normals" to 0.075 or to your liking.Ī surface that doesn't display a 'normal' is set so that it has its backface towards you. A tip here is to change the length of the displayed'normals' as it make them easier to see in complex models. This will make the modellook somewhat hairy. Selectorth->normals and 3D->normals to see them. You can see'normals' by turning them on in the 'orth' and 3D windows. The ray is ejected from the front surface only. A 'normal'is the direction a light ray would travel if it is ejected at right angles toa surface. Generally it is a good idea to check 'normals' at this point.
