In SolidWorks, showing dimensions in a drawing is an essential part of communicating design information effectively. By displaying dimensions, you can convey the size and position of features accurately. In this tutorial, we will explore different methods to show dimensions in SolidWorks drawings.
1. Basic Dimensioning
The most common way to display dimensions in a SolidWorks drawing is through basic dimensioning. This method involves using the Smart Dimension tool to add dimensions to sketch entities or model edges.
To apply basic dimensioning, follow these steps:
- Select the Smart Dimension tool from the Dimensions/Relations toolbar.
- Pick the desired sketch entity or model edge to dimension.
- Drag the dimension line and place it at the desired location.
- To modify the value of a dimension, double-click on it and enter a new value.
2. Ordinate Dimensioning
In some cases, using ordinate dimensioning can be more efficient and organized than basic dimensioning. Ordinate dimensions are useful when you want to establish a reference point and measure other features from that point.
To use ordinate dimensioning:
- Select the Ordinate Dimension tool from the Dimensions/Relations toolbar.
- Pick a reference point on your drawing as the origin for all ordinate dimensions.
- Select other features or points that you want to measure from this reference point.
- Determine their relative positions by dragging their corresponding dimension lines.
3. Baseline Dimensioning
Baseline dimensioning is another method for displaying dimensions in SolidWorks drawings. It allows you to create a baseline from which you can measure multiple features.
To apply baseline dimensioning:
- Select the Baseline Dimension tool from the Dimensions/Relations toolbar.
- Pick the first feature or point to include in the baseline.
- Select the subsequent features or points that you want to measure.
- Drag their respective dimension lines and position them as desired.
4. Chain Dimensioning
If you have a series of features with equal spacing, chain dimensioning can be a time-saving technique. It enables you to add dimensions to multiple entities in one go.
To use chain dimensioning:
- Select the Chain Dimension tool from the Dimensions/Relations toolbar.
- Pick a starting point on your drawing.
- Select all the subsequent entities that you want to include in the chain dimensioning.
Conclusion
In this tutorial, we explored different methods for showing dimensions in SolidWorks drawings. Basic dimensioning, ordinate dimensioning, baseline dimensioning, and chain dimensioning are all powerful tools that allow designers and engineers to communicate design information accurately and efficiently. By incorporating these techniques into your drawings, you can enhance clarity and ease of understanding for yourself and others involved in the design process.
Note: It’s important to remember that each method has its own advantages and may be more suitable for specific situations. Experiment with these dimensioning tools to find the most effective approach for your particular drawing requirements.
