MicroStation to AutoCAD Conversion

Question

Is there a list somewhere of MicroStation elements that do not convert to AutoCAD? Line style problems, fonts, leaders, annotation scale, cells, etc.

you might want to consider using DWG Workmode:

Best is to stick with DWG format only in case of multi-format environment then you will avoid any conversion problems. 
 What we do: 
 
 Use only RGB colors, no color code colors allowed. Still there are issues with invasion of unwanted colors or colorbooks. Seems this issue will never get fixed. 
 Use only text styles as textstyle(none) is not possible in DWG. Unfortunately Textstyles are flawed in Microstation so it is easy to corrupt text styles as for example justification is part of text style which is not the case in DWG . There is only one improvement in CONNECT Edition now regarding text styles so with such pace it will be fixed in CE Update 51 or something. 
 Use Shared cells but it is very inconvenient to manage them. 
 Do not use line codes(0-7), only custom linestyles and also custom linestyle even for 0 linestyle otherwise it gets converted to CONTINUOUS in DWG. Drawback is that custom linestyles are not hardware accelerated and can make file slow for very long lines.

not sure of a list but look up the help under save as DWG and you will see all the different settings under the options also good search keyin 
 " sharing DGN and DWG data" yielded a lot of useful information to consider.... 
 But generally what happens or you need to consider 
 DGN linestyles 0-8 are supported all custom linestyles are not ( unless they are already acad ones) 
 Cell convert to blocks 
 non truetype fonts ie Bentley fonts are not supported and you need the create shx option so the non true types are converted and acad can then read thenm but you have to allow the acader be able to find them so I like to send them to the same place the dwgs are ... 
 for dims here is option for dims to save the active dims settings and create inline leaders if you wan them... 
 entity mapping has a lot of things listed 
 and under advance there re options to drop things 
 and create true color from DGN colour numbers.... but this may not be compatible with dwg print settings 
 construction elements to const layer 
 there is loads of settings .. you need to look at them all maybe print the help and come up with your own setting for different types of dwgs needed....
