Help with conditional dimensions syntax

brian_jordan

In searching the help files I have found  the following

You can also use ternary operators (such as '?') which can yield conditional results. For example, say the length of a sketch entity should be 7 inches if the width is greater than 5 inches. It can be written this way:

#width>5?7:4

How can I incorporate this into an If... Else statement so that in one hit I can specify in addition eg #width>8?9.2:4 #width>10?12.4:4 I'm sure this is possible but for the moment the syntax escapes me.

Thank you

You're almost there - the biggest thing you are missing is units, plus you must test the larger value first otherwise the second "if" would never be reached. Parentheses around the embedded "if" are also required.

#width > 10 in ? 12.4 in : (#width > 8 in ? 9.2 in : 4 in)

You can nest additional ternaries anywhere you want in the expression.  I like to do something certain in the 'if' and then do more logic in the 'else' so I would phrase this like:

#width>10?12.4:(#width>8?9.2:4)

but some other ways would be:
#width>8?(#width>10?12.4:9.2):4
#width<8?4:(#width<10?9.2:12.4)

All work out to the same logic in the end

@NeilCooke @Jake_Rosenfeld Thank you both for your help. So near and yet so far!
