Uncover an innovative civil engineering tool that allows for quick visualization of terrain from multiple angles and facilitates the export of surveys in DTM format. This tool efficiently accommodates the import of large LiDAR Point Clouds for easy data analysis, while also enabling the integration of .xml and .dwg files into your favorite CAD software for seamless sharing. By utilizing an external database, it significantly bolsters data sharing functionalities. The software empowers users to modify surfaces by adding break lines and holes, as well as managing both 2D and 3D profile alignments, including those derived from LiDAR Point Clouds. It offers four unique methods for volume calculations: comparing surfaces, evaluating planes, analyzing cross sections, and assessing solids. Additionally, it simplifies Point Cloud data to generate surfaces, retaining only the essential points that accurately depict surface behavior. Users can conveniently position, shift, and rotate building footprints within a parcel while adhering to design constraints. The application also enables automatic parcel generation from survey points or existing drafts, enhancing efficiency. Moreover, it supports users in creating, editing, and triangulating surfaces by selecting points and break lines, proving to be an essential asset for civil engineering tasks. This comprehensive functionality not only streamlines workflows but also allows professionals to concentrate on design and analysis without facing unnecessary hurdles, making it an indispensable tool in the industry.
