Issue:
When opening AutoCAD, the specialized toolsets (for example, MEP, Architecture, Mechanical, Electrical) are not showing.
Causes:
Running core AutoCAD and not the desired vertical (toolset) program.
Solution:
AutoCAD "toolsets" are individual, separate programs and not add-ons or plug-ins which come with the core AutoCAD program. The desired AutoCAD vertical program (toolset) must be installed individually. Core AutoCAD is not required to be installed for an individual toolset.
For example, only AutoCAD Architecture needs to be installed for the program to operate.
