In 2020 Civil 3D, the Raster Design (RD) tab is on the ribbon and all the tool icons are visible once the tab is selected. However, the infamous "unknown command" pops up when selecting a tool from any of the RD palettes. The path(s) to the RD program and the Help files are in the support file search path in CD3. The AecCo.cuix file has been copied to the CD3 support directory and it still will not launch.
What is puzzling is that I have 2020 Map 3D installed as well with all the same paths, etc. as CD3 and RD actually runs - no problems. What is the issue with loading RD in the CD3 product?
