Topographic Survey Drafting
Contour modeling, spot elevation grids, surface TIN generation, and 3D grading meshes for civil designs.
Contour modeling, spot elevation grids, surface TIN generation, and 3D grading meshes for civil designs.
Topographic drafting illustrates the contours, elevation differentials, and physical landscape details of a parcel of land. At ArcusCAD, we convert your field spot elevation coordinates, breaklines, and field measurements into highly detailed topographic maps.
Using AutoCAD Civil 3D, we generate digital terrain models (DTM) and triangulated irregular networks (TIN surfaces) to draw accurate contour intervals, surface slopes, drainage patterns, and grading structures. This provides civil engineers and architects with a solid baseline map for construction, roadway, or storm-water drainage projects.
Contact UsWe process your coordinate databases (PNEZD formats) and place spot elevations. We cross-reference raw breakline points to maintain correct geometric slope lines.
We define boundaries, exclude bad shots, model retention ponds, and construct the TIN surface. Contours are generated and labeled with elevation text tags.
We format layout scales, place legends, draw elevation scalebars, insert grid crosshairs, and check contours against survey point notes.
