Alignments
autocad_entity: aec_alignment
Features with autocad_entity set to aec_alignment store alignment entities which represent centerlines, lanes, shoulders, right-of-ways, or construction baselines. Alignments can store a combination of lines and curves that are viewed as one object. Alignments can be stand-alone objects or the parent object of profiles, profile views, and cross sections.
