Megafunction library not found in ModelSim Altera

i've solved this vsim 3033 error by copying the 220model.v found in C:\altera\13.0sp1\quartus\eda\sim_lib into my modelsim working directory (for e.g. resource_library as in the Modelsim Tutorial pdf file - chapter 5 working with multiple libraries).

besides the parts_lib folder, i also created lpm_lib (optional and arbitrary name ) folder under the same resource_library folder to segregate my custom modules and altera lpm modules.

i then compiled the 220model.v in the resource_library directory into the lpm_lib library. it should be clearer if you refer to the tutorial pdf file page 39.

maybe it's not the proper method but it works for me.
