TopoGX

TopoGX is a software application which can intelligently convert a 2D DXF drawing into a useful 3D DXF drawing. It is intended for surveyor produced drawings like the one to the right here (click the image for more details), but is equally suited to any 2D drawing where the Z levels are represented as text items. Additionally TopoGX contains a powerful triangulation engine which can produce a constrained delaunay triangulation of a 3D drawing almost instantaneously. It features numeric text items are converted to Z levels, 2D arcs are converted to curved 3D polylines, automatic detection of block inserts which are suitable for level assignment, the 3D lines and polylines are used as constraints for the surface triangulation, Z levels are assigned to line and polyline features wherever appropriate, 3D Height Coloring shades your converted DXF Surface according to level, and Shows your 3D surface instantly and allows quick viewing of any survey errors or inconsistencies.
