Autocad offers a handy Mline command, allowing users to craft Mline styles with specific attributes. One particularly ideal application of this command is in delineating on-site curbs. However, there's a snag: unlike the ease of inputting 'a' or 'c' to form arcs or curves when creating polylines or pressure pipes, this functionality isn't readily available for Mlines.
Introducing an upgraded mline tool for use in Civil 3D could be a straightforward enhancement with myriad possibilities. For instance, it could streamline the preliminary layout of sites by employing Mlines for curbs, resulting in substantial time savings compared to the use of fillets and offsets. It could be rolled out as an update to vehicle tracking, but I personally believe it has a place right inside basic Autocad or Civil 3D.
