DGNLib is a small c / C library to read and write DGN files.Building: This is a preliminary source distribution, and I did not go to any trouble to make it easy to configure and build. To build please do the following: 1. Updated cpl_config.h to represent your platform with precision. Usually all that matters is # define WORDS_BIGENDIAN on big endian platforms. The rest can probably be ignored.2. Compile the sample program. On Unix, this can be done something like this:% gcc dgndump.c *. cpp-lm-o dgndumpWhat New in this version: · This release adds support for BSplines, shared definitions of cells and text nodes. · 3D solids and surfaces has been fixed.
