How do you create a basic dimension in Solidworks?

How do you make a basic dimension?

To create basic dimensions: In a part, click Smart Dimension (Dimensions/Relations toolbar) or Tools > Dimensions > Smart. In the Dimension PropertyManager, under Dimension, click DimXpert basic location dimension .

What is a basic dimension on a drawing?

In Geometric dimensioning and tolerancing, basic dimensions are defined as a numerical value used to describe the theoretically exact size, profile, orientation or location of a feature or datum target.

What is considered a basic dimension?

What Are Basic Dimensions? Basic dimensions describe the theoretically exact location, orientation, size, or profile of a feature or datum target. Because basic dimensions are theoretically perfect dimensions, there are no tolerances associated with them.

How do I set dimensions in SOLIDWORKS?

To configure a dimension:

1. Select a feature, sketch, or mate in the FeatureManager design tree to make its dimensions visible in the graphics area.
2. In the graphics area, right-click a dimension and click Configure Dimension .
3. In the Modify Configurations dialog box, you can: Create new configurations.

Do basic dimensions have to come from a datum?

Basic Dimensions

The basic dimension originates from the datum. The basic dimension is enclosed by a rectangle. Basic dimensions are used to establish the “true profile” which a profile tolerance will then control. So if a profile tolerance is applied to a hole, the diameter MUST be a basic dimension.

Can a basic dimension be a datum?

Basic dimensions can indeed be used to define the location of a feature, or to define the location of a datum on a feature. For example for a sheet part, one point on a straight edge might be the secondary or tertiary datum, and it’s location along the edge could be defined using a basic dimension.

What is the difference between a reference and basic dimension?

A basic dimension is a dimension of where a feature is theoretically located (or where it is intended to be located). It must have some other tolerance to it from GD&T. A reference dimension is just there to reference, but can be completely taken off the drawing to make sense.

When should you use basic dimensions?

Basic dimensions are used to establish the “true profile” which a profile tolerance will then control. So if a profile tolerance is applied to a hole, the diameter MUST be a basic dimension. There are two methods of dimensioning described in Y14. 5: rectangular coordinate dimensioning and geometric tolerancing.

What are the the 3 basic dimensions of a project?

Every project is constrained by three dimensions: time, budget, and scope.

What are the only two purposes basic dimensions?

What are the only two purposes Basic dimensions serve? Basic dimensions serve to orient and locate 1) tolerance zones and 2) Datum Targets. 7.

How many basic dimensions are shown?

There are three different types of dimensions on prints: Reference Dimensions, Tolerance Dimensions, and Basic Dimensions. We’ll review brief descriptions of each and then dive deeper into Basic Dimension.

What is dimension Standard SOLIDWORKS?

in SolidWorks, dimension formatting follows the standard that is set for the document in tools, Options, Document Properties, Drafting standard by default. You can change the document or template defaults for each type of dimension listed under tools, Options, Document Properties, Dimensions.

How do I show dimensions in SOLIDWORKS 2019?

To re-display the dimensions, right-click the feature or one of its faces, and select Show All Dimensions. To show dimension names, click View > Hide/Show > Dimension Names or Hide/Show Items > View Dimension Names (Heads-up View toolbar).

How do you change dimension to MM in SOLIDWORKS?

Go to Tools>Options>Document Properties>Units to change the units that are being used within the SOLIDWORKS design environment. There is also the units’ popup menu in the bottom right-hand corner of the SOLIDWORKS screen.
