Autodesk removed the ability of C3D installs to have a shortcut to run "plain" AutoCAD Map starting with C3D 2023. This was yet another unwanted "feature" by Autodesk. There is no functional or logical reason to remove the shortcut from C3D installs. C3D already comes with core AutoCAD and there is no reason to have to install AutoCAD separately. Autodesk's "solution" just adds gigs of wasted space to a workstation for absolutely no benefit to the user.
