How to extract only a region from a DXF/DWG file
Posted: 22 Sep 2005, 11:58
Hello
I am currently testing CAD Import VCL, it looks very good. I have a special quesion:
We develop a program for displaying environmental data (e.g. groundwater level) as contour maps. Some of our clients want do display DXF/DWG plans (roads, buildings etc.) in combination with the contour maps which are created with our software. But often the contour map covers only a certain (rectangular) region of the CAD plan, which means that only a part of the CAD plan has to be displayed. The boundaries of the contour map are known (in world coordinates), can I tell CAD Import VCL to read only those elements which are inside the rectangle defined by our contour map?
