Curved construction objects and radial grids

In this video we introduce two new construction objects (construction arc and construction polycurve) and a new command to copy construction objects.  We also introduce the new radial gridmodeling aid that represents a three-dimensional complex of horizontal and vertical planes

In Tekla Structures, grids are used as an aid in locating objects in a model. The grid is shown on the view plane by dash-and-dot lines.
