Hello
What is the purpose of the square symbol under the diameter symbol (see image) in the properties of a dimension in a drawing?
It is a symbol that is added before a coast like the diameter symbol.
Kind regards.

Personally, I use it when I have a square shape to side

So it must be able to be used for both extrusion and material removal?
Good evening
I confirm what @stefbeno has just written ! Normally reserved for profiles (the main ones have their symbol for example HBA! Personally, I use it for square profiles, it allows me to put only one dimension instead of two. NF ISO 5251
But I find these symbols a little too limited for example it's the same symbol for IPN or HEA HEB, etc which means that you always have to put the annotation that goes well :-(
Kind regards

This is good for square profiles, the equivalent of Phi for diameters.
