Does SolidWorks have any way to read in data from Unigraphics?
Yes. SolidWorks includes a translator which allows for the import of native Unigraphics part and assembly files. SolidWorks and Unigraphics use the same modeling kernel Parasolid®. Instead of sending the data through translators such as IGES and STEP, the Parasolid file format (usually *.xmt_txt) is available for import and export. This capability allows you to bypass IGES and STEP, providing you with a cleaner data exchange between SolidWorks and Unigraphics products.
