Part 12: What We Found, What We Have
- Obtaining Drawing Information


CAD is constantly storing accurate, detailed information about objects in your drawing. You can utilize all this information at any time to get details through the use of commands that measure distances, calculate areas, angles, properties of objects, etc.

Additional Object(s) Information

Tables can be created and/or inserted (attached) in the drawing. Information can be embedded into the objects themselves, called Block Attributes.

Showing Information of Your Drawing

At any time you can display the following types of information:

Information about selected objects.

Status of the current drawing.

Calculating Distances and Angles

CAD accurately tracks every point location in the drawing in relation to the underlying Cartesian coordinate system, the program can very quickly calculate the distance between any two points that are selected.

See figure at right.

Calculating Areas

You can easily calculate the area and perimeter of any enclosed object, or the area enclosed by a polygon that is formed by a series of points that you specify.

See figure at right.

What are Block/Cell  Attributes ?

An attribute is a label or tag that attaches data to a block. Examples of data that might be contained in an attribute are material, weight, dimensions, etc. See figure below.


A table is a compound object that contains data in rows and columns. It can be created from an empty table or a predesign template.

See table to right.

Tables - "Spreadsheet"

A table can also be linked to data in a spreadsheet. See figure at right.
