A Minimum Distance sensor is one example of how Design Sensors monitor design dimensions. |
The Variable sensor monitors variables from your variable table. Sheet Metal sensors offer specifics such as monitoring internal faces that warn bends are too close together to be manufactured. A Surface Area sensor is helpful if you need to know how much surface finish is required or the minimum surface area for heat. If you need something outside the box, you can use a custom sensor to monitor any numeric result that is calculated from a custom program. For example, you could create a custom program that assigns a manufacturing cost to each feature type used for creating sheet metal parts.
When a monitored condition is out of range, sensor alarms and violations are highlighted in the sensors tab in Edgebar and graphically in the upper right corner of the graphic window. Clicking this graphic launches the Sensor Assistant, which provides hyperlinks to all the sensor violations and warnings in the document.
Click the Design Sensor alarm to launch the Sensor Assistant. |
Design Sensors are quick and easy to set up; you should use them in any situation in which critical dimensions must be within range. In this exercise, I'll create a Design Sensor to watch a minimum distance between the edge of a hole and the edge of a plate it is placed through. Other types of sensors work in a similar fashion, so once you know the workflow in this exercise, you will be able apply other types of sensors.
Start by creating a plate 150 mm square, and place a 15 mm hole in the corner that is located 30 mm from each edge.
Create the base geometry. |

The Sensor Assistant keeps track of sensor alarms that have been triggered by changes to the model. It quickly accesses the affected sensor definition information so you can review it and fix the alarm or the model as needed.
You can activate or deactivate the Sensor Assistant and alarm notification in the graphic window using the Show Sensor Indicator option on the Helpers tab of the Tools / Options dialog box. This does not affect the operation of the sensors themselves.
For more detailed information on sensors, the Solid Edge Help menu has more advice on how they work, the kinds of sensors available, and even some great examples. If you're not already using sensors, try them out. They will help you reduce costly design errors and costly prototypes.
See you on the Edge next time.
