Select an object to change or : Now select the arc to lengthen Select an object or : T (Do NOT select the object enter T for Total) With the Lengthen tool you can set the object’s total length, including the Arc length: It could of course be done by calculating the angle mathematically, but an easier way to do it is to draw the arc with the required radius and centre point, then modify it using the lengthen tool on the Modify tab drop down. You can define the chord length with Start, Center, Length, but in this case we want to define the arc length, not the chord. The problem with the arc is that you can draw arcs in over nine ways but none of those specify a length of the arc. This set me thinking and trying out a number of possible options.

This Catenary program for AutoCAD and BricsCAD makes it easy to create or draw a catenary curve as a polyline by specifying the start and end point and the length or sag and optionally a diameter(width).Ī catenary cable is hanging from 2 base points.Whilst teaching a recent AutoCAD course I was asked by a boat designer how to construct / draw an arc of a specific length. The other properties of the catenary are: Length, Sag, Incline Sag and Tension at sag. Specify one property and the catenary is determined. You can also specify an immediate point for the catenary to go through. You can draw multiple catenaries with length or sag or incline sag increasing. Alternatively, enter variable names at the command prompts. Select the color you want for the background. In the search field, enter background color and then hit Enter. You can also draw multispan catenary by picking more than 2 points. To change the color of the screen background, follow these steps: Enter the Settings command. If your picked points have Z coordinates, it is assumed that catenary will be hanging down in 3D space, and the catenary will be drawn in 3D.

Th eTORIENT command also allows the selected text to be aligned to a segment of line (or polyline).

This can be useful for drawing freely hanging cable, hose, chain, transmission line, anchor line (anchor rode), cord, rope, string, suspension bridge cable, arch, hawser, wire, zip lines or the like. TORIENT (CADPower-> Text-> Display -> Text Orient: Make Text / Mtext readeable): Missing from BricsCAD, now available through CADPower. The current version is creating a catenary line using the catenary formula y = cosh(x) = (e^x + e^-x)/2 and numeric analysis that results in a good enough curve for many purposes. How to create catenaries go through immediate pointsĪ parabola is different from a catenary. The parabola does not have the same property.Ĭatenary described according to Wikipedia: The catenary is the solution to a differential equation that describes a shape that directs the force of its own weight along its own curve, so that, if hanging, it is pulled into that shape, and, if standing upright, it can support itself. In physics and geometry, the catenary is the curve that an idealized hanging chain or cable assumes under its own weight when supported only at its ends.

The curve has a U-like shape, superficially similar in appearance to a parabola (though mathematically quite different). It also appears in the design of certain types of arches and as a cross section of the catenoid - the shape assumed by a soap film bounded by two parallel circular rings. The catenary is also called the "alysoid", "chainette", or, particularly in the material sciences, "funicular".
