CAD software for surveying

You can do triangulation, isolines, color-filled contour maps, sections, intersections, volume, editing XYZ point files, drawing 4D point cloud files and simulation of rainwater runoff.

It has its own CAD system, called RCAD

No need for another CAD system.
RCAD CAD system, distributed together with RTOPO Hydrology, provides OpenGL real-time orbit, pan, zoom, shading, lighting and motion path animation. RCAD is similar with other popular CAD systems and can load and save DXF files. It has entries in the command text area, graphics area, menus and toolbars and can run scripts.

Simulation of rainwater runoff

You can thus identify the watershed, the direction and meaning of the water flow, the flooded areas, the speed and level of the water. You can set: the amounts of precipitation and infiltration into the soil in m/(sec*m2), the roughness of the land, the calculation time increment, the duration of the precipitation, the total duration >= the duration of the precipitation and drawing the water level at every moment.

About the software

You can process hundreds of thousands of points or triangles, even on less powerful PCs.
Through its own CAD system (called RCAD), specialized for 3D and for a large number of entities, you can do:
-load and draw a file of points having the format: Number X Y Z Code; the drawing is made by POINT,3DPOLY,SPLINE or BLOCK entities, according to a modifiable library of codes,
-edit interactively the XYZ files of points; you can modify the coordinates, the code and the position (in 3DPOLY or SPLINE),
-triangulate the points on a convex hull or between an external contour and possibly more interior contours,
-contour lines and color-filled contour map,
-cross sections and longitudinal profile,
-the projection of several PLine entities over a triangulation
-simulation of rainwater runoff; identifies the watershed, the direction of the flow, the flooded areas, the speed and level of the water,
-the conversion of a triangulation to a regular grid of points,
-the conversion of the existing isolines resulting from maps in points and then in a triangulation,
-represent the geological_stratification resulting from drilling,
-calculate 3D area, center of gravity and the volume between 2 triangulations,
-intersect and divide two triangulations or a triangulation by a horizontal plan,
-interpolate a set of 3DFACE, using quartic triangular patches
-transform a drawing containing entities as PLine, Line, Block and Text, in XYZ points file,
-represent 4D points cloud,
-import and export LandXML.
