Every dimension has a shown or implied tolerance, the dimensions shown as HOLD are the dimensions that are not to be affected by the stack up of tolerances of the holes or features around them.
An aligned dimension is a type of dimension in technical drawing and design that is positioned parallel to the feature it measures, ensuring clarity and precision. This type of dimension is typically placed to the right or above the feature, allowing for easier reading and interpretation without needing to rotate the drawing. Aligned dimensions are commonly used in architectural and engineering drawings to convey measurements clearly and accurately.
Dimension.
In a technical drawing, a hexagon bordered number typically indicates a specific type of dimension or annotation related to the geometry of the object being represented. It often signifies a reference or a standard that must be adhered to, such as tolerances or specifications. The hexagonal shape can also denote a special note or requirement that is crucial for the interpretation of the drawing, distinguishing it from other annotations.
Drawing a spade or club.
It basically means the measure of the size of an object. Such as a shape is measured in length.
An underline on a dimension means that it is not to scale.
Scale provides the ability to measure a depicted feature or arrangement of features on the drawing, and scale it to what it was / will be in the real world. It is not always possible to dimension every possible feature, and a scaled drawing allows someone to infer what a given dimension will be.
Ref usually means that this dimension (and any associated tolerancing), is specified somewhere else, possibly on a lower level sub-assembly drawing.

It means you can't look at it or you'll go catatonic Cute. Actually, it means that the entity that is being "referenced", usually a dimension, should NOT be inspected. It might be an overall length of the part. This might be a "cut length" for the machinist where the actual required dimension is shown elsewhere on the drawing.
A reference symbol inside a basic dimension symbol indicates that the dimension is referenced to a specific datum or feature in the design. This helps clarify the relationship between the dimension and the referenced feature, ensuring accurate interpretation and manufacturing. It enhances the precision of technical drawings by providing context for where the measurement is taken from.
It means that when you do a basic configure shape on your type 2 Three-Print paper you must hold your dick in a conservative manner.

"NS" on a blueprint typically stands for "not specified" or "not shown." It is used to indicate that a specific detail or dimension is not provided on that particular drawing and may need to be clarified or determined through other means.
Dimension.
Drafting means actually drawing the drawing.
