Try this:

EDIT SELECTION MODEL TYPE LEVEL
EDIT SELECTION MODEL FILTER "170"
EDIT SELECTION MODEL TYPE COLOUR
EDIT SELECTION MODEL FILTER "181,102,0"

if max(apply(folder('model'), "number_selected('model', this.Name)")) > 0 {
	message info 'Found a surface'
}

hello, if it isn't a furface but a bidimensional line?

[icse]

yes, this should also find lines.(everything in lvl '170' with your given color '181,102,0')

Apply:

string apply( list list, string expression )

Returns a new list consisting of the values obtained by applying 'expression' to each element of the input list list. In the expression you can give the keyword this to refer to the current list item

Example: Add "_1" to a list of strings
STRING LIST mlist = {'a', 'b', 'c', 'd'}
STRING LIST ulist = apply(mlist, "this + '_1'")
print ${ulist[0]}
// prints "a_1"
print ${ulist[1]}
// prints "b_1"
Example: To find the minimum Z value of the toolpaths in an NCProgram
PRINT = min(apply(folder('ncprogram'), 'limits(this)[4]')) 

max:

real max( list numeric a )

Find the largest value in a list of numbers.
