I have tested many (probably all inclusive vectordraw there is very expensive but also very professional) dxf readers on the market. All of them had so many bugs that I could not build up my project with these toolboxes. Your toolbox is probably the most bugfree on the market. The first task I would suggest you to do is to make a better documentation. All the other products had normally a good documentation and where easy to get started with. This is a little harder with your tool.
CADSoftTools team comment: Now we have made a completely new help system which works similar to Delphi VCL Help. All developers who used the former manual, please take our apologies for the difficulties with the old help files and we thank you for your understanding.
