TLCatenaryA

Generates a catenary curve using a base point and a parameter "a" specified by the user

TLCatenaryA3d

Launches the TLCatenaryA command in 3D mode. This mode changes the coordinate system internally so that the vector of gravity is aligned with the Z axis of the current/active UCS and the Catenary XY plane is aligned with the two control points. All coordinates are still transformed back to the current UCS, but the Catenary equation parameters are reported in the internal coordinate system

TLCatenaryLength

Generates a catenary curve using a start and end points and a total length specified by the user

TLCatenaryLength3d

Launches the TLCatenaryLength command in 3D mode. This mode changes the coordinate system internally so that the vector of gravity is aligned with the Z axis of the current/active UCS and the Catenary XY plane is aligned with the two control points. All coordinates are still transformed back to the current UCS, but the Catenary equation parameters are reported in the internal coordinate system

TLCatenarySlope

Generates a catenary curve using a start and end points and a slope at a location all specified by the user

TLCatenarySlope3d

Launches the TLCatenarySlope command in 3D mode. This mode changes the coordinate system internally so that the vector of gravity is aligned with the Z axis of the current/active UCS and the Catenary XY plane is aligned with the two control points. All coordinates are still transformed back to the current UCS, but the Catenary equation parameters are reported in the internal coordinate system

TLCatenarySag

Generates a catenary curve using a start and end points and a sag specified by the user

TLCatenarySag3d

Launches the TLCatenarySag command in 3D mode. This mode changes the coordinate system internally so that the vector of gravity is aligned with the Z axis of the current/active UCS and the Catenary XY plane is aligned with the two control points. All coordinates are still transformed back to the current UCS, but the Catenary equation parameters are reported in the internal coordinate system

TLCatenaryBulge

Generates a catenary curve using a start and end points and a bulge specified by the user

TLCatenaryBulge3d

Launches the TLCatenaryBulge command in 3D mode. This mode changes the coordinate system internally so that the vector of gravity is aligned with the Z axis of the current/active UCS and the Catenary XY plane is aligned with the two control points. All coordinates are still transformed back to the current UCS, but the Catenary equation parameters are reported in the internal coordinate system

TLCatenaryVerticalBulge

Generates a catenary curve using a start and end points and a vertical bulge specified by the user

TLCatenaryVerticalBulge3d

Launches the TLCatenaryVerticalBulge command in 3D mode. This mode changes the coordinate system internally so that the vector of gravity is aligned with the Z axis of the current/active UCS and the Catenary XY plane is aligned with the two control points. All coordinates are still transformed back to the current UCS, but the Catenary equation parameters are reported in the internal coordinate system

TLCatenaryArea

Generates a catenary curve using a start and end points and enclosed area specified by the user

TLCatenaryArea3d

Launches the TLCatenaryArea command in 3D mode. This mode changes the coordinate system internally so that the vector of gravity is aligned with the Z axis of the current/active UCS and the Catenary XY plane is aligned with the two control points. All coordinates are still transformed back to the current UCS, but the Catenary equation parameters are reported in the internal coordinate system

TLCatenaryPoints

Generates a catenary curve trough three known points specified by the user

TLCatenaryPoints3d

Launches the TLCatenaryPoints command in 3D mode. This mode changes the coordinate system internally so that the resulting catenary lies in the 3d plane defined by the control points and the vector of gravity is aligned with the Z axis of the current/active UCS as close as possible. All coordinates are still transformed back to the current UCS, but the Catenary equation parameters are reported in the internal coordinate system. The catenary curve will pass through all 3 points but the direction of gravity may deviate from the Z direction depending on the configuration of the input points. The resulting curve is still sensitive to the orientation of the UCS and different UCS systems will result in different curves for the same set of control points

TLCatenaryBestFit

Generates a catenary curve by performing a least squares error function optimization on a set of input points. The Error function is defined as the sum of squares of the catenary residuals at every point in the set. In addition to the standard output a residuals list is generated for all input points along with the final value of the error function.

TLCatenaryBestFit3d

Launches the TLCatenaryBestFit command in 3D mode. In this mode the least squares optimization is computed in multiple stages. During the first stage a best fit 3d plane is derived off of the set of control points. This plane is then used to compute a catenary local coordinate system taking the UCS gravity vector into account. Finally a best fit least squares analysis is computed during the third stage. Note that the function minimization during the first stage is performed orthogonally to the plane whereas in the third stage the vertical distance (along the Y or Z vector) is minimized. As is the case with the CatenaryPoints3d command the resulting curve is still sensitive to the orientation of the UCS and different UCS systems will result in different curves for the same set of control points.

TLCatenary3dActivate

Activates the TL Catenary 3d App with the Autodesk App Store. Active internet connection is required. Once activated the app can be used offline. This command is not available in the ribbon and needs to be manually typed in at the AutoCAD command prompt
