Inverse

  • The Inverse function calculates distances and geometric relationships between a reference position and a selected reference object.

  • Calculations can be performed from a base point or directly from the current position.

  • From COGO page select Inverse.

Calculation method

  • Select the reference object against which the calculations will be performed.

  • The following object types are supported:

    • Point: calculates the distance and related information between a base point and a reference point, or between the current receiver position and a reference point.

    • Line (2 Points): calculates the distance and related information between a base point, or the current receiver position, and a line defined by two points.

    • Arc (3 Points): calculates the distance and related information between a base point, or the current receiver position, and an arc defined by three points.

    • Arc (2 Points + Radius): calculates the distance and related information between a base point, or the current receiver position, and an arc defined by two points and a specified radius.

    • Drawing Object: calculates the distance and related information between a base point, or the current receiver position, and a drawing element selected from the graphic view.

Inverse to a Point

  • The software calculates the distance and related information between the base point and the selected reference point.

    • Ref point: select from CAD or from point list the reference point. Press > and select Measure to measure a new point.

    • Point 1: reference point; it’s calculated the distance between the base point and the reference point or between current position and the reference point.

  • Press Next to start the calculation.

Inverse to a Line (2 Points)

  • The software calculates the distance and related information between the base point and the selected reference line.

    • Ref point: select from CAD or from point list the reference point. Press > and select Measure to measure a new point.

    • Point 1: first point defining the reference line.

    • Point 2: second point defining the reference line.

  • Press Next to start the calculation.

Inverse to an Arc (3 Points)

  • The software calculates the distance and related information between the base point and the selected reference arc by 3 points.

    • Point 1: first point defining the reference arc.

    • Point 2: second point defining the reference arc.

    • Point 3: third point defining the reference arc.

  • Press Next to start the calculation.

Inverse to an Arc (2 Points + Radius)

  • The software calculates the distance and related information between the base point and the selected reference arc by 2 points and radius.

    • Point 1: starting point of the reference arc.

    • Point 2: ending point of the reference arc.

    • Radius: radius of the reference arc.

    • Clockwise Arc: defines the direction of the reference arc.

  • Press Next to start the calculation.

Inverse to a Drawing Object

  • The software calculates the distance and related information between the base point and the selected CAD drawing object.

  • Select the reference drawing element directly from the graphic view.

  • Press Next to start the calculation.

Calculation result

  • Software shows the distance and other values calculated.

    • Create Point: creates a new point at the calculated projection of the base point on the reference element.

    • Stakeout: starts the stakeout procedure to guide the operator to the calculated projection of the base point on the reference element.
