RemarksThe positionings describe an additional translation of sections. Basically, the positioning is a vector having the length 'length' and an orientation that is described by the parameters 'sweepAngle' and 'dihedralAngle'. If the 'sweepAngle' and the 'dihedralAngle' are set to zero (or left blank) the positioning vector equals the positive y-axis of the coordinate system (in case of a positive 'length').
If the parameter 'fromSectionUID' is set, the positioning describes the translation between the 'from' towards the 'to' section. If the parameter 'fromSectionUID' is left blank the orgin of the positioning vector is the origin of the parent coordinate syste.
The orgin of the section coordinate system is the position which is described by the positioning vector PLUS the translation which is described in the section.
Please note: If the orgin of the positioning vector is defined by using another section, i.e. fromSection is defined, the orgin of this vector equals the end of the positioning vector of the previous section. This means that the section translation of the from-section has no influence on the positioning of the to-section. Therefore the total translation, which is described by positionings, is the sum of the current positioning and all positionings that are defined 'before'.
An example for this is given at positioning 3 and 4 at the picture below. Please note, that any other combination of positionings would be possible.
Application of the sweepangle does not lead to a rotation of the section. Application of the dihedral does not lead to a rotation of the section.
