You should be able to recreate them yourself. Rename the folder your templates are currently in then try to start a new template. SolidWorks should create new default templates. You can also do a search in your SW install folder; there is normally a tutorial folder that contains templates. Two words of advice: create backups
Thanks for responding.
I got my Drawing Template from SW Install Folder.
Thanks & Regards
BTW you can use an existing drawing, remove all unwanted stuff and save as Drawing Template.
