Quicksurf generates contours or surface meshes for topography starting from x, y, z files, digital elevation models or extracted drawing entities, such as spot elevations or contour polylines. 3D breaklines defining elements such as building pad perimeters, roads or geologic faults may optionally be used. Contours may be based on a TIN, grid or triangulated grid. Contouring directly on the TIN (Triangulated Irregular Network) is common in civil site design. Contouring on the grid allows for smooth curved surfaces between your data points. Contouring on the triangulated grid (unique to Quicksurf) allows both smooth curving surfaces and exact honoring of breaklines. Optional contour line indexing, annotation, hachuring, and color options are available. More about topography.

Quicksurf can display your surface colored by surface slope in percent or degrees, complete with colored legend showing the slope breakdown. Iso-slope contours may be created and draped onto the surface in 3D. Creating slope analysis maps is quick, easy and flexible. A larger version of this image is available on the topography page.

3D flowlines represent the 3D path a drop of water would take if placed on the surface. A flowline perpendicular to a contour line. Flowlines are a great way to check drainage designs or delineate watersheds.

Thickness (isopach) maps represent the thickness between two surfaces. For example, an isopach between the top and base of a coal seam would be used for mapping the distribution of the coal seam. A thickness map between an existing and a design topography is the basis for cut and fill volumes. Thickness maps are created by subtracting two elevation surfaces, such as an existing and a design topography, or the top and base of a geologic unit. Quicksurf includes much more than just subtraction: over 30 surface to surface mathematical operations are included, including trend analysis and slope analysis.

Creating building pads set into the existing topography is painless. If the pad is slightly sloping, create a temporary surface by specifying two points and a slope, draw the pad perimeter polyline and drape onto the design slope. Supply the cut slope and fill slope angles and Quicksurf's intersect slope command will project the slopes from your pad perimeter and calculate the head of the cut and the toe of the fill and draw the resulting daylight line in 3D. Create a new design surface by selecting the daylight and perimeter lines as break lines and your done. Check the cut/fill volumes and adjust to balance your material volumes.

Quicksurf is used by many private firms and government agencies to map coastal and navigable waterways, reservoirs and rivers. Profiles, cross-sections, water and sediment volumes are generated quickly and easily. Quicksurf may be configured to handle line-based survey data which choke many slope based modeling packages.

Modeling contaminant distribution with Quicksurf uses the Kriging capability of the program. Interactive variogram design allows you to create custom semi-variograms to match the transport characteristics of the contaminant - stratigraphy combination. Logarithmic contours may be used or irregular contours based on specific contaminant thresholds may be generated. Several maps may be combined to show the relationship between the contaminant and bedrock topography, stratigraphy or ground water surfaces.
