The default surface style sets the appearance of the surface that is created, provided that it isn’t changed during the application process.  It can be accessed through the command settings in the Toolspace environment.

I am writing this while my computer chugs on a HUGE data file I am importing, and it occurred to me that I don’t remember what the default style is for this project.  I have had some large surfaces to load, and occasionally failed to get the drawing stabilized, not because there is a problem with the data file (besides the huge size), but because after it is loaded, there is not enough memory to display it.

Reduce the overhead by creating a default style that has the least amount of displayed information as possible.  For me it is 10’ contours using continuous lines or just a border.  This way when the beast is displayed, you can get a grip on the drawing before you run out of resources.
