How to keep aspect ratio fixed, when rotating 3D objects in GUI?

I know that you can fix the aspect ration by right clicking on the axes and choosing: Rotate Options > Fixed Aspect Ratio Axes. But I'd like my GUI to do this automatically without every time manually specifying that? Is there a way to problematically achieve this? (ex.: including a command in the opening function)
thanks

DataAspectRatio and DataAspectRatioMode are among the properties cleared when a cla() is done, whether implicitly or explicitly. cla() is done implicitly each time you invoke a high-level graphics routine such as plot() and you do not have "hold on" or "hold all" turned on for the axes.
Therefore, instead of setting the properties in your opening function, set the properties after you plot.

I did set those properties right after creating my object too, but didn't give me the desired result!
It was only after using "axis vis3d" that the aspect ratio was fixed during 3d rotation.
thank you

Maybe this will do what you are trying to accomplish?
axis vis3d

yes.. I came across "axis vis3d" and that solved my problem, but you have to write that every time after setting all other axes/object properties.

yep! I have this in the opening function, as well as right after when I create my graphical object. The funny thing is that the "Fixed Aspect Ratio Axes" is checked on, but the graphics still acts as if not fixed. If I manually turn it off and on it will be fixed!! can it be a bug?

Set the axes' DataAspectRatio and DataAspectRatioMode properties to the necessary values.

I did that already in the opening function. Unfortunately, I still have to check the "Fixed Aspect Ratio Axes" option manually on the axes :(

hmmm, so you have something like:
set(handles.axes1,'dataaspectratiomode','manual');
set(handles.axes1,'dataaspectratio',[1 1 1]);
and it still comes undone?
