Cone Measurement

Easson2D supports probing the cone surface at multiple heights with the probe and generating a cone element from the acquired spatial measurement points.

The probing method for cone measurement is basically the same as for cylinder measurement: points must be acquired in layers at several different heights on the cone surface.

1. Select Cone Measurement

Click:

Probe Measurement → Cone Measurement

to enter the cone measurement state.

Once in the function, move the probe to the cone surface to be measured and acquire points.

2. Acquire a Group of Points at the First Height

First, select a height position on the cone.

At the same height, acquire points evenly around the cone. Each group requires at least:

3 measurement points

It is recommended to spread these 3 points around the cone instead of concentrating them on the same side.

This helps determine the circular cross-section at that height position more reliably.

3. Continue Acquiring Points at Other Heights

After completing the first group, move the probe to another height position on the cone.

At the new height, acquire points around the cone again:

At least 3 measurement points per group

Therefore, cone measurement should include measurement groups at at least two different heights.

For example:

Layer 1: 3 pointsLayer 2: 3 points

If the cone is tall, or if you want more measurement points, you can add more measurement groups at additional heights.

Since the cross-section diameter of a cone changes with height, measurement data from different heights can be used to establish the entire cone geometric element.

4. Complete the Measurement and Generate the Cone

After acquiring all the required probe points, right-click:

in the image area or the geometry area

to end the current probing operation.

Easson2D calculates the measured cone from the points acquired at different heights and generates the corresponding cone element.

Basic Workflow

Cone measurement can be summarized as:

Probe Measurement → Cone Measurement → Acquire at least 3 points around the cone at the first height → Acquire at least 3 more points at another height → Add more measurement groups at other heights as needed → Right-click in the image area or the geometry area → A cone element is automatically generated

Point Distribution

During cone measurement, pay attention to point distribution both around the circumference and along the height.

Around the Circumference

Measurement points at the same height should be spread evenly around the cone.

Avoid concentrating points within only a small arc.

Along the Height

Measurement points must be distributed across at least two different heights.

Keep a reasonable distance between different heights so that the measurement data reflects the change in cone diameter along the height direction.

If all measurement points are concentrated at the same height, only the circular cross-section at that position can be determined, and a complete cone element cannot be established.

Measurement Recommendations

For more stable cone measurement results, it is recommended to:

• Acquire at least 3 valid measurement points at each height
• Spread the points at the same height evenly around the cone
• Take points at at least two different heights
• Keep a reasonable distance between different heights
• For taller cones, increase the number of measurement heights and points
• Avoid burrs, notches, and clearly abnormal surface positions
• Ensure all measurement points come from the same measured cone surface

A reasonable circumferential distribution and height span help Easson2D establish the cone element more reliably.
