! EIGHT hours of work LOST!!!
I have had several instances lately where TC has crashed causing hours of lost work.
Turbocad autosaves the drawing every 10 minutes by default.
In the event of a crash .... look in the Autosave Folder, open the last Temp file, Save it as a TCW with a variation of the correct named file. (reason for a variation file name, is so that it does not overwrite the original file, just in case it is corrupt / etc)
Buy opening up the Autosave file, means that the worst you have lost is 10 minutes.
You can also look in the Backup Folder and open that file ... Save it as a TCW with a variation of the correct named file.
This will give you 3 variations of the same file and will show the different stages of when they were last saved.
Also ... Crashes do happen ... so make a habit of Saving
I Save files when >> i have competed a Stage, taking a break, before i Render, before i Print.
