Measuring landcover area with respect to soil group

Question

Hello Bentley, 
 I have one query. I want to measure my landcover area with respect to soil group.I already create my soil map and also have landcover map for same location. 
 Suppose I have 3 acres of woodland if you straight measure in landcover map. But if you measure same area with respect to soilgroup the same area may have 1.5 acre in soil group C, 1 acre in soil grop D and 0.5 in soil group B. 
 Color red, blue and yellow are soil groups and green is with landcover. 
 Is there any way to measure these area quickly by loading these two files in microstation ? 
 Attached are the files for example. 
 
 Thank you so much for your time.

for v8i that is what I use so how I would approach this sorry for the long answer but its a lot of steps to get it right.... 
 1. you need to make sure in both ref files every area is a real polygon ie shape not complex string etc 
 2. you need to have by level settings and each type on its own level name ie all the reds on the same level name... 
 Now your greens could be separate level names would be best if your only going to use cad to do your analysis .. 
 3 best option is to export these dgns to a comptable format and import into a GIS package , if you dont have one then QGIS is free ... 
 unfortunately you will need to export each level as a separate DXF if you use QGIS...( FYI MapInfo does it better and easier than QGIS) 
 or 
 with only cad then....instead of 3 use only xrefs into a holding file turn off all the greens polys, and work you way each of green poly level by level ( manual) 
 now 
 4. select the first green polygon and use fence clip copy to capture everything inside the green poly and copy away from the actual site over an away to the right or left .. 
 after you have clip copied it you can turn off the fence and select all of the copied elements and from properties you can identify each coloured area and its individual area which you can copy paste into excel or notepad you can even assign which green shape it was ie level name green1, green2 etc 
 repeat for each green polygon or dont select any if you just want totals latter you turn off the xrefs and select all the copied shapes by their level name and get totals per level name by the selection and measure area tool by level and do the same in the xref and the differnce would be outside the green shapes... 
 If you use item 4 
 you first must have the enhanced fence copy in the user preferences turn on so shapes self heal and stay shapes with clip copy.... 
 The entire process does work but its very tedious and easy to make mistakes when your getting tired which you will... as its all manual 
 To sum up this is so much easier in a real GIS like map info which will import all your dgns as dgn with levels and shapes ( real polygons only) and give you the answer for each green shape as a areas inside or contained by... this is a very simple sql query and it ends up in a table to export or copy to excel etc.. from what you have shown this would take me less than 30 mins or any gis operator (if the data was good...)
