do not find the button found with funnel in 2010 autocad

[Alex97]

Hello.
1) with autocad properties 2007 at the top right with the funnel button I select all the design and I could look for all the lines of a color, a layer etc, now this button where is it?
2) I was making a calculation of a surface so I was going along the edges of a figure and in the end I did not exit the surface, on the command line appears "object may not be self-intersecting" what does it mean?
3) Can you do a dash on a prospectus and use this dash to calculate the surface of the dotted part and then that net of the windows?

Thank you.

It's always there but now it has a green rectangle symbol with lightning

2) I was making a calculation of a surface so I was going along the edges of a figure and in the end I did not exit the surface, on the command line appears "object may not be self-intersecting" what does it mean?

means you clicked the points in the wrong way

3) Can you do a dash on a prospectus and use this dash to calculate the surface of the dotted part and then that net of the windows?

si certo.

2) and how do I know if I clicked a wrong point, but how do I use the same procedure then other times without problems?
3) if I do the purified retino of the windows where I have to click to have the surface of the retino?

Sorry how to get the post report on my email address, I scratched in my profile this possibility but I don't get this report.
Thank you.
