Picking Cylinders (v.36 and earlier)

Menu: Survey / Pick Cylinder

The Pick Cylinder tool enables users to detect cylindrical objects within the point cloud and place a survey point at the base of each detected cylinder. This tool is particularly useful for identifying poles, pipes, and structural columns in surveying and infrastructure projects.

✔ Activate the tool and click on a point that is part of a cylinder.
✔ The system will attempt to detect the full cylinder automatically.
✔ If detection fails, adjust the following settings:

• Increase point cloud density (if too sparse).

• Modify detection parameters in Menu: Settings / Objects / Cylinders:

  • Min/Max cylinder radius

  • Minimum number of points required for detection

✔ Once a cylinder is detected, it will be added to the Explorer under Objects → Cylinders.
✔ The user must pick a point on the screen to determine the elevation.
✔ The Pick Points/Lines window will appear, registering the bottom center of the cylinder as a survey point.

✔ Continue picking cylinders until:

• No further cylinders are detected.

• The Pick Points/Lines window is closed.

✔ Note: Even if the survey points are not saved, the detected cylinders remain in the Explorer for later use.

✔ Fast & Accurate Detection – Automatically detects cylindrical objects.
✔ Efficient Surveying – Places survey points at the base of each cylinder.
✔ Customizable Parameters – Adjust detection settings for optimal accuracy.
✔ Seamless Data Integration – Detected cylinders are stored in the Explorer for further processing.

With the Pick Cylinder tool, users can efficiently identify and vectorize poles, pipes, and columns, enhancing CAD, BIM, and GIS workflows. 🏗️📍
