In AutoCAD, dimensioning is a crucial aspect of creating accurate and precise technical drawings. It allows designers and engineers to communicate the exact measurements of various objects within their designs.
AutoCAD provides a range of dimension commands that enable users to add dimensions to their drawings in different ways. Let’s explore some of the commonly used dimension commands in AutoCAD.
Linear Dimension (DIMLINEAR)
The Linear Dimension command, also known as DIMLINEAR, is used to add dimensions for linear objects such as lines, arcs, and polylines. This command allows you to specify the start and end points of the dimension line, along with the position of the dimension text.
Aligned Dimension (DIMALIGNED)
If you want to add dimensions that are aligned with an object but not necessarily parallel or perpendicular to it, the Aligned Dimension command (DIMALIGNED) is what you need. This command allows you to create dimensions that follow the angle or orientation of the object being measured.
Angular Dimension (DIMANGULAR)
The Angular Dimension command, also known as DIMANGULAR, is used to measure and display angles between two lines or edges. With this command, you can easily add angular dimensions for objects such as polygons, circles, or any other shape with distinct angles.
Radial Dimension (DIMRADIUS)
When working with circles or arcs in your drawings, the Radial Dimension command (DIMRADIUS) comes in handy. This command allows you to add dimensions that measure the radius or diameter of circular objects accurately.
Diameter Dimension (DIMDIAMETER)
Sometimes it’s necessary to specify the diameter rather than just the radius of a circular object. That’s when you can use the Diameter Dimension command (DIMDIAMETER). This command enables you to add dimensions that display the diameter of circles or arcs.
Ordinate Dimension (DIMORDINATE)
The Ordinate Dimension command (DIMORDINATE) is used to add dimensions for objects that are aligned with a specific reference point. With this command, you can establish a baseline and measure the distance of various objects from that baseline, making it easier to create accurate technical drawings.
Baseline Dimension (DIMBASELINE)
In some cases, you may need to create dimensions that are parallel and equidistant from a common baseline. The Baseline Dimension command (DIMBASELINE) allows you to do just that. It helps you quickly measure the distance between objects along a common line or baseline.
Conclusion
These are just some of the dimension commands available in AutoCAD. Each command serves a specific purpose and helps designers and engineers accurately communicate measurements within their drawings. By utilizing these dimension commands effectively, you can ensure precision and clarity in your technical drawings.
