We have been using CAD VCL as part of our aluminium costing software in South Africa for the past several years. We have had absolutely no problems with the software. Each time there was a change to the AutoCAD file format, CAD VCL were very prompt to release an update that ensured compatibility. We are in the process of re-writing our software in the latest version of Delphi and we will most definitely use the CAD VCL libraries in our new software.
