When working with SolidWorks, it is important to know how to show reference dimensions. Reference dimensions are measurements that are used for reference purposes only and do not affect the actual geometry of a model. They are useful for providing information about the size or position of features without actually modifying them.
Why Use Reference Dimensions?
Reference dimensions serve several purposes:
- Clarity: By including reference dimensions, you can provide additional information about the design intent and help others understand the model more easily.
- Communication: When collaborating with others, showing reference dimensions can be helpful in conveying your ideas and ensuring everyone is on the same page.
- Measurements: Reference dimensions can be used as a starting point for taking measurements or creating relationships between features.
Show Reference Dimensions in SolidWorks
In SolidWorks, there are several ways to display reference dimensions. Let’s explore some of the common methods:
Method 1: Using Smart Dimension
The most straightforward way to show reference dimensions is by using the Smart Dimension tool. Here’s how:
- Select the Smart Dimension tool from the Dimension toolbar or from Tools > Dimensions > Smart.
- Select an edge, face, or feature to dimension.
- In the PropertyManager, check the “Display as reference” option.
- Enter the desired dimension value.
- Click OK to apply the dimension as a reference dimension.
You will notice that reference dimensions appear in gray by default, distinguishing them from regular dimensions that affect geometry directly.
Method 2: Converting Regular Dimensions to Reference Dimensions
If you already have regular dimensions in your model that you want to convert to reference dimensions, follow these steps:
- Select the dimension you want to convert.
- Right-click and choose “Display as reference” from the context menu.
The selected dimension will now be converted into a reference dimension.
Method 3: Changing Dimension Type
Another way to show reference dimensions is by changing the dimension type directly. Here’s how:
- Select the dimension you want to change.
- In the PropertyManager, locate the “Dimension Type” section.
- Select “Reference” from the dropdown menu.
The dimension will be updated and displayed as a reference dimension.
Conclusion
In conclusion, showing reference dimensions in SolidWorks is essential for providing clarity, facilitating communication, and enabling measurements. By using tools like Smart Dimension or converting regular dimensions, you can easily incorporate reference dimensions into your models. Remember that reference dimensions are non-parametric and do not affect the actual geometry, making them valuable for design documentation and collaboration purposes.
