The AutoCAD vertical product forums are intended for questions, comments or tips and tricks that are specific to one or more of the vertical products. For example, a question about survey data or grading should be posted in the AutoCAD Civil 3D forum. Whereas, a question about dynamic blocks should be posted in the AutoCAD Drawing Management forum, even if you are using Civil 3D. Following this simple logic will help to keep the forums neat and will enable others to more easily find what they are looking for.
