I have been getting an issue message that says, 'An item with the same key has already been added.'
the above message will appear if there are 2 or more alignments with the same name. Civil Site Design does not recognise the case of the alignment name.
Alignment_One and alignment_one are considered to be the same name and therefore will display the 'An item with the same key has already been added.'
Renaming one of the alignments (to a unique name) will resolve this issue
