Italian Developer Paolo Rossi has created two sets of externals for PowerCADD 7: Topography Tools and Architectural Extensions.
These tools are for topographic survey, the acquisition and analysis of topographic data. The tools allow you to place a reference point object in the drawing that has a Z height and name as well as the normal X and Y location.
These objects can be imported from or exported to a text file. In PowerCADD you can do a 3D interpolation of the points, and it is also possible to automically draw a section of the terrain surface.The locations are in global coordinates, so it is possible to import X,Y,Z points from a text file and put these points over a parametric map.These points can be exported to a text file containing the name and X, Y, Z coordinates of the point. So you can import these points to another program that can handle the coordinate data.With IPaRos Topography, you can add new points, and you can also:
Twelve tools for topographic work.
• create new points interpolating in 3D space existing points;
• insert two topographic symbols
• create sloped terrain symbols;
• create a middle line between two lines, polygons, or curves;
• create a section profile of the terrain.
