Wire types, diameters, tensions, and linear weights. 2. Geotechnical and Environmental Inputs
The geometry of a power line is defined by its cable tension and sag. O-calc Pro Line Design moves beyond simple parabolic approximations, employing a precise hyperbolic catenary curve formulation to model how cables hang between structures. The software accounts for physical changes such as thermal elongation due to temperature fluctuations, ice loading, and the effects of wind pressure on the conductors.

The concept of a is what turns a collection of poles into a unified "Line Design." In the inventory window, each cable type displays a chain-link icon, signifying that this span is linked to the corresponding span on the adjacent pole. A jumper cable is the physical manifestation of this link, showing how the cable is routed from an insulator on one pole to the next. The true power emerges when a change is needed. If an engineer decides to upgrade the primary conductor along a five-mile circuit, instead of editing the attachment on every single pole, they simply drag the new conductor type from the catalog and drop it on the primary span of any pole in the line. A prompt appears, asking if the substitution should apply to "This Segment" or the "Entire Circuit." Choosing "Entire Circuit" replaces the conductor across every linked pole, maintaining consistency and preventing errors.
