In Pro Panel API it is sometimes necessary to recognize sides of 3d object, for example to place them in a row with the same orientation.
Please mind that the sides of a Placement3D is something different that sides of its minimal bounding box. They are related to the same part of object 3d, independently of a transformation and a viewpoint.
The representation of sides is in .Corners property, for example :
Placement3D.Corners.UpperRightBackAbsolute – returns upper right back coordinate in absolute system
Placement3D.Corners.LowerRightFrontRelative – returns lower right front coordinate in relative system
In this case orientation is according to placement area.
Example terminal :
Example rack:
In this cas,e orientation is according to absolute axis origin (assumed identity transformation) :
Front : side with the lowest Y
Back : side with highest Y
Right : side with highest X
Left : side with lowest X
Top : side with highest Z
Bottom : side with lowest Z
SE isometric viewpoint :
SW isometric viewpoint :
