Hi,
I was wondering if there are any advantages or disadvantages in regards to setting drawing limits. I never set my drawing limits, I also never have the grid toggle on either.
I have never given limits much thought and argued with many people that there is nothing magical about 0,0,0 having to be in the lower, left hand corner of your drawing. And the grid gets in the way, visually, and is not needed if you use osnaps and relative coordinates to draw and place entities.
A good argument for 0,0,0 having to be in the lower, left hand corner of your drawing, is Xref's can be attached at the same coordinates and copy base point works the same way. The lower left corner is just a good point to remember.
I also do not used grid.
I think you have written about the ACAD-command "_limits". I never set my drawing limits, too.
You can use it, if you want to plot from modellspace. "limits" are like the paper.
If you use the rasterpoints (F7). They are shown only inside the limits.
If you want, that nobody draws outside the limits. LIMCHECK.
I use limits in layouts when I plot. Particularly useful when I have a "D" or "E" size drawing and I just want to plot from either drawing size a portion of that drawing on an "A" size.
