Have you ever wondered why you have set the VIEWRES in one drawing and then when you open another drawing, it has changed even though you may have changed it using the OPTIONS dialog box?
There are some settings that are only saved in the current drawing and then there are others that are saved to the “registry” that will take effect in the next drawing that you open. If you want any of these “current drawing” settings to be set for you automatically, this is where saving your drawing as a template (.dwt) is very helpful.
In the OPTIONS dialog box, if there is a little (.dwg) symbol next to the setting, that means that any changes to that setting will only be saved for the current drawing. Also notice at the top to the OPTIONS dialog box, that there is the symbol next to the text that says “current drawing”…
The next time you are in the OPtions dialog box, have a look around and notice what settings are for the “current drawing.”
