Carlson Software’s Precision 3D (P3D) Topo 2017 — designed for surveyors, civil engineers and contractors — allows users to import survey data, points, polylines, surfaces, point clouds, traditional LiDAR and aerial drone survey data from a wide variety of programs and entities to create useable 3D surfaces.

“P3D Topo enables much faster design and analysis in the 3D environment than the many step processes of the CAD world,” says Carlson’s Nathan Crews, lead developer of Precision 3D. “Its 3D design tools save lots of time and reduce the chance of errors, making it an obvious tool to improve the business bottom line.”

Designed with ease of use in mind, Carlson P3D Topo also provides fast point cloud editing of .las, .laz, .ply, .xyz, .pts, .e57, and .pcd files, which allows users to reduce the size of the point cloud and still have an accurate surface, view large areas for environmental or overview needs, merge overlapping point clouds and crop to just the area desired, and import other spatial data such as DEM, GeoTiff, Jpeg2000, georeferenced jpg and shape files.

Then, 3D surfaces can be created and merged from the imported files.  P3D Topo allows for real-time surface editing with dynamic contours, faces and slope arrows, with easy-to-execute drag and drop design. Unlimited undo and redo allow users to study their changes and make things perfect as they can view the 3D surface with user-controlled textures to quickly spot errors in the DTM.

Carlson P3D is designed to help contractors perfect files for use for machine control — they can go in and create a design surface of the TIN and bring the TIN into P3D to make sure the machine control files are good.

“Editing tools include surface blending, spike and dimple removal, DTM vertex editing, and surface pad placement by defined polygon and sideslope conditions,” Crews says. “Surveyors, contractors and engineers alike can use the software to make sure the final DTM surface is of the highest quality.”

Carlson touts P3D as useful for presentations when the audience, such as a town council or a client, might not be able to read or understand construction drawings. In addition, with its built-in LandXML 2.0 import/export, users have the ability to export the files to Civil 3D, Esri geodatabase, Trimble, TTN, Topcon, TN3 and STL in addition to Carlson.
