Respond to the prompts to select the wires and specify parameters such as wind direction, required horizontal and vertical clearances, and so forth. A clearance envelope is displayed in the drawing and clearance violation status is indicated on the command line.
Before running the command:
After running the command, respond to the following prompts:
Select a catenary overhead wire. The clearance envelope will be generated for this wire. You will be able to choose the sag scenario to be used for the catenary geometry or a set of two sag scenarios to create an interpolated range between both.
Select another object to which clearance needs to be checked. This may be another wire or any type of AutoCAD solid or surface object. If another wire is selected you will have the option of choosing the sag scenario to be used or a set of two sag scenarios to create an interpolated range between both.
Indicate a sag scenario to be used for the catenary wire(s). The same scenario will be used for both wires if checking clearance between wires.
If wishing to check an interpolated range between two scenarios, specify another sag scenario for the catenary wire(s). If no interpolation is needed, choose the same scenario as in the prior prompt. The same scenarios will be used for both wires if checking clearance between wires.
The wind direction will be applied perpendicular to the wire with the exact direction dependent on the wire's start and end points. Use this prompt to reverse the wind direction if necessary.
This will define the horizontal extent of the clearance envelope, generated around the initially selected catenary wire's geometry (or interpolated geometries if two different scenarios were selected). The value is in default length units of the industry model (for example, in the US template it will be feet).
This will define the vertical extent of the clearance envelope, generated around the initially selected catenary wire's geometry (or interpolated geometries if two different scenarios were selected). The value is in default length units of the industry model (for example, in the US template it will be feet).
After these prompts, the system will generate a clearance envelope, optionally an interpolated surface for the second wire if two scenarios are being checked, and potentially a conflict object to indicate areas of clearance violation. These objects will be generated on the currently active AutoCAD layer.
Indicates no intersection was found between the wire's clearance envelope and the object to which clearance was being checked.
Indicates a violation was found between the wire's clearance envelope and the object to which clearance was being checked. The area of overlap between the clearance envelope and the other object will be indicated by a red solid or surface object.
Choose Yes to erase the generated clearance objects or No to keep them. After this prompt, the command ends.
