You can convert most CAD formats between each other if you first export the original to some exchange format like DXF or DWG and then import that to the other CAD program. In this case SLDPRT to DXF and DXF to X_T for example. Other than that, you can also find dedicated CAD converters like the CrossManager that can directly convert from one format to another regardless of vendor.

Convert from sldprt file format
The tables with software actions are a good pointer for what a certain program does with various file types and often may give users a good hint how to perform certain file conversion, for example the above-mentioned sldprt to x_t. However, it is not perfect and sometimes can show results which are not really usable because of how certain programs work with files and the possible conversion is thus actually not possible at all.
