Make guide is greyed out

[mnmlrgrt]

The object is selected, yet the make guides is greyed out.
If there are any idea why, would be appreciated

[Kurt Gold]

What kind of object is selected?

Is it perhaps already a guide? Or something else?

[mnmlrgrt]

it is a text

[Kurt Gold · Accepted solution]

That won't work with live type objects.

You would first have to outline the type object (convert it to paths).

See Type menu > Create Outlines.

Kurt,
Is it also possible this same limit might be the same for "live" polygons?

[Kurt Gold]

I don't think so, Larry.

At least I'm able to convert polygons (live shapes) to guides.

Astonishingly, Illustrator is courteous enough to make them amphibious, that is: they are actually guides, but at the same time still live shapes that can be modified through the Transform palette.
