Mathematica: why does the 3D plot remember the last point of view / rotation it made, even after evaluating it again?

I find it a little annoying.

I am making a 3D graph, initially it appears in the default orientation. Then, using the mouse, I rotate it somehow.

Now I run the command again, expecting to get the original form (i.e. the original orientation, before I turned it with the mouse), but instead it just gives me the same plot that I have on the screen, i.e. seems to have saved / memorized the last point of view in this output cell.

I wanted him to return to the starting point. So, I delete the output cell to make it happen.

How do you think it works? Forcing to remove cell output is annoying when I try. I think it should return to the original default orientation.

Graphics3D[ Cuboid[{-.1,-.1,-.1},{.1,.1,.1}], AxesOrigin->{0,0,0}, PlotRange->{{-1,1},{-1,1},{-1,1}}, Axes->True, AxesLabel->{"X","Y","Z"}, Ticks->None]

If you run above and then move the plot and then run the command again, you will see what I mean.

version 8.0.01

EDIT:

Stranger: I added a viewpoint parameter to make it display by default, but the same result. He remembers the last point of view. The following is the default view using.

  Graphics3D[ Cuboid[{-.1,-.1,-.1},{.1,.1,.1}], AxesOrigin->{0,0,0}, PlotRange->{{-1,1},{-1,1},{-1,1}}, Axes->True, AxesLabel->{"X","Y","Z"}, ViewPoint->{1.3,-2.4,2}, Ticks->None]

I find it strange.

Try:

 With PreserveImageOptions->False, settings for image options from the previous version of a graphic are always ignored.

In your Mathematica notebook, draw your plot, then orient it the way you like.

Then place the cursor to the left of PLOT OUTPUT and type "AbsoluteOptions [" Then place the cursor to the right of PLOT OUTPUT and type "]" Shift-Enter

You will get a ton of information. Find ViewPoint, and then use this as an option in your graph. Then you will always have the same orientation.

I like to think of restarting the Plot command as updating an already created graphic. In the end, he does not make a second plot.

From this point of view, if I rotate or change my drawing, I do not want Mathematica to mess around with it when I add a shortcut or change the style.

However, if I remove my graphic to begin with, Mathematica uses the default rotation and size.

Therefore, I consider the behavior logical and appreciated.
