What is the meaning of "1 TYP"dimension in the below figure

Hi friend, good morning, TYP is TYPICAL, and it means that all dimension, mentioned in your drawing or in your figure, will be 1 inch. that word is usual on drawings. I hope my comment have usefull for your knowledge.

Whatever comments, or suggetions they are welcome.

Have a good day,

I agree with Hugo, just want to add something. This is used to avoid repetitive dimensions. The following text from

https://en.wikipedia.org/wiki/Engineering_drawing_abbreviations_and_symbols
can help you understand this better.

TYP means 'Other features share the same characteristic. For example, if the drawing shows 8 holes on a bolt circle, and just one is dimensioned, with "TYP" or "(TYP)" following the dimension label, it means that that hole is typical of all 8 holes; in other words, it means that the other 7 holes are that size also.' However, now it has been replaced by a more clear notation for such dimensions. 'The latest revisions of Y14.5 deprecate "TYP" by itself in favor of the specifying of a number of times, such as "2X" or "8X".'

So, in your drawing 1 TYP means there is same amount of offset (1 unit) around that sketch.
