Chapter 27 Storing Data in a Drawing
Creating Fields
You can create fields to hold data you want to store in the drawing. A field is
a user-defined property. On the Database menu, click Options to create a new
field.
Before adding new fields, you should ask yourself what type of data you want
to store. For example, if you are planning a computer network, you might
want to know how much cable you need. To store this data, you could create
a Cable Length field. If you are creating an electrical schematic, you might
want to know the tolerances of the resistors in the circuit. To store this data,
you could create a Tolerance field.
Once you know what type of data you want to store in a field, you are ready
to select its type. Every field must be one of five types:
You can have many fields in a drawing, but each field you create must have
a unique name. The field name should describe the data it contains because
it appears when you request information about an entity. Field names can
contain letters, numbers, spaces, and punctuation marks.
When you are naming fields that you plan to export to another application,
consider that some programs do not support the use of blank spaces, special
characters like an underscore (_), or punctuation. If this is the case, it is best
to use only letters and numbers in field names. AutoSketch can validate field
names to limit them to ten characters where the first character is a letter and
remaining characters are letters, numbers, or underscore characters.
