As long as the Separation distances have been defined to take account of the gaps between walls and ceilings/floors then all modules will treat the adjacencies properly. If any internal surface is flagged by ModelIt as having an external adjacency then you should review the distance as thermally these will be considered with external air at the boundary.
Aesthetically, there is no quick way to remove the gaps between rooms if you have built the model this way. In future you may wish to attach the dxf but then manually trace over it following the convention of outer surfaces for external walls and centreline for internal partitions then define your Constructions with the appropriate thicknesses and use Inner Volumes in ModelIT to get a true representation of room areas/volumes.
Hope this helps for future reference,

I wouldn't trust the ConstructDXF as far as I could throw it.
Considering the problems that you'll get with it for later stage design it's simply not worth the time "saving" bringing in the geometry quickly. Get the coffee on, switch the phone off and get tracing - you'll get far better modeling results snapping to grid and ensuring your points are exactly where you want them. Considering the life of the project you'll probably be more comfortable knowing your model build is solid and you don't need to worry about little bits of external wall sitting in your partitions because there's a gap between adjacent rooms.
Having said that... if you are doing early design stage feasibility then it's fine - no point going to the nth degree of accuracy if you are working on a few early proposed designs and are only after a flavor.
