If that is the only place it shows (91.5°) Then 88.5 degrees is good enough because it is a Reference Number. In other words they are saying somewhere in that ball park. If you can show us that 91.5° without ( ) then don't worry about it
Switch the order of feature selection and maybe it'll switch to the correct side of the angle. Sometimes you can type in the angle you want and it will correctly determine that angle.
A reference dimension is just what it sounds like. It is a dimension shown for reference. In other words it is there for informational purposes only.
They are not a requirement in any way.
Reference dimensions can be used to clarify other dimensions on a drawing. In some instances, they make a drawing easier to understand.
Reference dimensions on blueprints
How are reference dimensions shown on a drawing?
There is no
GD&T symbol for a reference dimension. Reference dimensions are shown on a drawing as a value enclosed in parentheses.
An alternate method is to follow the dimension with “Reference” or “Ref”. The use of “Ref” or enclosing the dimension inside parentheses are by far the most common notations used. These notations are specified in
ASME Y14.5 the Dimensioning and Tolerancing standard.
When to use a reference dimension
Reference dimensions are useful for clarification purposes. Their inclusion can make it clear how another dimension should be inspected or manufactured.
At other times they are included to make the drawing easier to read. It isn’t always immediately clear what a part looks like by looking at the blueprint.
A very common use of reference dimensions is to provide a conversion of the length units of the drawing from either metric to inches or vice versa.
Watch out for these conversions! Too often they are rounded excessively and not accurate.
Reference dimensions should never be used for acceptance..
I will say this though, since you find it so important to record this number, you are totally ignoring the other number, The (4X) and your reporting it based off the average of the cone, You need to make 4 lines at 90° apart from each other and report them separately, If you're going to waste your time with a Reference number you should do it this way.
I'm new to programming and just trying to get it right, just trying to learn. That is what I was going to do, but I don't have a lot of time to get this done. I was asking for advice, not some stupid comment like I'm supposed to know everything...
