I am considering purchasing Autocad LT for a Mac and have a few questions. I will be receiving files from the full version of Autocad that I will need to open and edit. I will not be doing anything 3d just drafting floorplans, elevations, etc. Will I be able to do this with the LT version? Also, if these files are coming from a windows based system will I have trouble working with them on a Mac. Any information would be helpful. Thanks!
