In Solidworks, you should be able to create template (.slddrt) from an existing drawing (.slddrw), so you can in the future quickly create new drawings based on the same settings. It is unlikely that you can create or use these templates in 3rd party software, so Solidworks remains your only choice for slddrw to slddrt conversion.

The table with program actions contains information about what each program is capable of doing with their files. This may be a good pointer for further searches for certain file conversions and help you find the converter you are looking for if our search result is insufficient for you. However, it is far from perfect and may sometimes show results which are not really usable because of the nature of the software handles the files. So a conversion that appears as possible, just because of matched actions, may in fact not be possible.
