Coordinate Transformation

How do I transform a calculated alignment between coordinate systems?

Answer: This can be done in the Alignment Design dialog via 'Tools > Coordinate transformation'.

Why does my alignments become jagged when transforming a Quadrimodel between different coordinate systems?

Answer: This is because a geometric line, like an alignment, need to fit 100% if the should look good. A transformation will shift the points of the curves and straights slightly so they are no longer tangent in the points between the different elements. In many cases the alignment will no longer be properly defined, and you may see strange results.
To solve this you do as follows:

NOTE: This only works for coordinate transformed alignments that has previously been used in our Novapoint Alignment Design tool as it stores extra geometry data to the task.

How can I transform a road model between coordinate systems?

Answer: When doing a coordinate transformation of a Quadri modeo, then the results of a roadtask/model will be transformed. Note that a road model design is related to an alignment, and any recalculation of a roadtask/model is dependent on the alignment to be in the correct position.

Note:  Be aware that the chainage could be shifted slightly. This depends on the coordinate systems that is used in the transformation. This can also affect chainages in the start/end of alignments added through 'Alignments as Surface Edge' or other parts of the description that no longer match. This could result in errors or warnings in the calculation.

How do I import a road model from another project that needs coordinate transformation to fit the new project?

Answer: This must be done in multiple steps.
