top controls and fitting

[Novembrine Waltz]

I'm writing because the absurdity of this situation is making me alter.
I have autocad version 2011.
I am following at the university a course in which they also make some basic lessons of autocad (which in fact I already know a little use since they are at the iii year of architecture). 2 times ago he taught us to use the top tool and he says that I never used for example.
Today I find myself trying to use them and they do not succeed in any way!
I ask you, maybe give me a hand.

I believe two lines, joined at the right angle.
example use fitting.
asks me "select the first object or." and various options I choose "route".
then specific a measure.
select the first line. as it tells me "select the second object or select the second object by holding down the maiusc key to apply the corner".
with neither of the two options creates me this fateful corner.
same thing with top. specific the two distances but it does nothing to me.

I'm really freaking out because it's the theme of one of the exercises. Where am I wrong?

the online command guide should help you solve the doubts or problems you find... anyway. . .
holding shift (maiusc) the two commands apply the angle, i.e. join the two selected lines without applying radius or bevel. the usefulness of this function is found when you have to connect two unparalleled quays apart using a command only and few mouse clicks; otherwise you should use methods that require minimum two commands with all the steps that this entails.
clarified this, which maybe was where you were stuck, the top and radius command works the same way...
1- select the command
2- Select the option to set the radius and bevel value
3- Select the first line
4- Select the second line.
Of course the radius or bevel must not be larger than the lines, but in this case a message appears to you.
in case of polylinea after setting the value select the option polyline and select a single segment of the perimeter

a possible reason why it may not make the berry or bevel is that the elements are not on the same floor. in practice if you have a z of different lines can't join them.

I tried. calmly (because then I acted).
And I understand. in practice if I gave bigger values (which, a square of 3x3 units, gave it the value of radius 45) did not give me the error message. in practical my mistake that I wrote the value of the angle instead of that of the radius (and there because it seemed to me that the prof also had the angle option, maybe I don't have it?) but autocad didn't warn me that I was doing a stuff out of measure compared to the selected lines and made me obviously extra my view.

the angle option exists only in the top command (securely the prof was referring to this)
the case of the maiusc+clik button on the second line has been mistranslated so as to confuse the user, because there is no angle (as you have been told) but only a connection (or a top) with zero radius (or top).
