In SolidWorks, a vertical ordinate dimension is a type of dimension that measures the distance or height of an object from a defined reference point. It is an essential tool for accurately dimensioning 2D sketches and 3D models. However, there may be instances when you need to continue a vertical ordinate dimension across multiple features or parts in your design.
Continuing a Vertical Ordinate Dimension in SolidWorks
When working with complex designs or assemblies, it is common to have multiple features or parts that require vertical ordinate dimensions. To continue a vertical ordinate dimension in SolidWorks, follow these steps:
Step 1: Create the Initial Vertical Ordinate Dimension
To begin, create the initial vertical ordinate dimension for the first feature or part. This can be done by selecting the appropriate reference points and using the Smart Dimension tool.
Example: Let’s say we have a design with two parts – Part A and Part B. We want to measure the height of both parts from their respective base planes.
- Select the first feature or part (Part A) and choose two reference points that define its height.
- Go to the Annotations tab and click on Smart Dimension.
- In the graphics area, select one reference point, drag your cursor vertically, and click on the second reference point.
- A dimension line will appear, indicating the measured distance between the two reference points.
Step 2: Add Additional Vertical Ordinate Dimensions
To continue the vertical ordinate dimensions across multiple features or parts:
- Select the next feature or part (Part B) that you want to measure.
- Choose two reference points that define its height.
- A new dimension line will appear, but it won’t be vertically aligned with the initial dimension.
Note: By default, SolidWorks creates a new vertical ordinate dimension that starts at zero. To continue the dimension from the previous feature or part, you need to modify its properties.
Step 3: Modify Dimension Properties
To modify the properties of a vertical ordinate dimension:
- Select the dimension you want to modify by clicking on it.
- In the PropertyManager, under Type Properties, change the “Start value” to match the value of the previous dimension.
Note: The “Start value” represents the distance between the selected reference point and a defined zero position along the vertical axis. By setting it to match the previous dimension, you ensure a continuous vertical ordinate measurement.
Step 4: Repeat for Additional Features or Parts
If you have more features or parts that require vertical ordinate dimensions:
- Select each feature or part in sequence.
- Create a new vertical ordinate dimension using two reference points.
- Select and modify each subsequent dimension’s properties as described in Step 3 to continue from where the previous dimension left off.
Note: It’s crucial to maintain a consistent “Start value” for all vertical ordinate dimensions to ensure accurate measurements and a visually organized design.
Conclusion
In SolidWorks, continuing a vertical ordinate dimension is essential for accurately measuring the height of multiple features or parts in a design. By following the steps outlined above, you can create a visually engaging and organized design with continuous vertical ordinate dimensions.
