When drawing in AutoCad, you have the option of adding dimensions to your drawings. Dimensions are entered using the following commands: Linear Dimension is used to measure the distance between two points, Angular Dimension is used to measure the angle between two lines, Radius/Diameter Dimension measures the diameter or radius of a circle or arc, Edit Dimension allows you to edit all previously created dimensions, Continuous Dimension allows you to continuously add dimensions one after the other.
What are dimensions in CAD?
Dimensions in CAD are annotations that indicate important dimensions and details of objects in a drawing. They specify lengths, angles, radii, diameters and other geometric attributes required for accurate design and manufacturing. Common types of dimensions include linear (for straight-line distances), angular (for angles between lines), radial (for radii of circles or arcs), and diameter dimensions. They ensure precise communication of the design intent, and enable correct layout and implementation by engineers, manufacturers, and designers. Dimensions are important to verify that the physical product matches the design specifications and facilitate quality control and consistency.
Types of dimensions in AutoCAD:
To add dimensions in GstarCAD using various commands and techniques, including linear, angular, radius/diameter, editing dimensions, and continuous dimensions, follow the steps below:
1. Linear Dimension:
Command: DIMLINEAR
Type DIMLINEAR in the command line and press the Enter key.
Click on the first point of the object you want to dimension.
Click on the second point.
Position the dimension line and click to place it.
2. Angular Dimension:
Command: DIMANGULAR
Type DIMANGULAR in the command line and press the Enter key.
Click on the first line.
Click on the second line or specify the vertex.
Position the dimension line and click to place it.
3. Radius/Diameter Dimensions:
Radius dimensioning Command: DIMRADIUS
Type DIMRADIUS in the command line and press the Enter key.
Click on the arc or circle.
Position the dimension line and click to place it.
Diameter dimensioning Command: DIMDIAMETER
Type DIMDIAMETER in the command line and press the Enter key.
Click on the circle or arc.
Position the dimension line and click to place it.
4. Editing dimensions:
Command: DDEDIT
Type DDEDIT in the command line and press the Enter key.
Select the dimension you want to edit.
Change the text, dimension style, or other properties in the edit window.
Press Enter or click outside the editing area to apply the changes.
5. Continuous dimensions:
Command: DIMCONTINUE
Type DIMCONTINUE in the command line and press the Enter key.
Select the dimensioning you want to continue.
Click on the end point or the centre point of the object you want to dimension.
Repeat the process to add continuous dimensions to other objects.
These commands allow you to efficiently add and edit dimensions in CAD to ensure that your drawings are accurately labeled and clearly communicated.
Please note that while the trial offers full access to GstarCAD’s features, it is limited to a specific duration. After the trial period expires, you may need to purchase a license to continue using the software.
Dimensioning in GstarCAD?
Dimensions in GstarCAD, similar to AutoCAD, are important annotations that indicate the exact dimensions of objects in a drawing. These dimensions ensure accurate interpretation and implementation of the design.
In GstarCAD, dimensions can be customized through styles that control aspects such as text size, arrowhead and units to ensure they meet specific project requirements. The Dimension Style Manager in GstarCAD, similar to AutoCAD, allows the user to efficiently create, modify and manage these dimensioning styles. This functionality ensures that drawings are not only accurate, but also clear and consistent, facilitating effective communication.
