Walls laid up in running bond (with offset head joints), on the other hand, exhibit a similar geometric configuration at the individual courses with the exception that the ends of units in alternating courses project out beyond the faces of the units immediately above and below (Figure 2). Curved walls laid up in stack bond (i.e., with vertical head joints aligned) possess the geometric properties of a regular polygon (Figure 1). The bond pattern also impacts the overall appearance of a curved wall section. The curvature of these walls depends on variables such as the length and thickness of the concrete masonry unit, the width of the vertical head joints at the interior and exterior wall faces and whether the units will be used as is, beveled at the ends, or cut to conform to the desired radius. The greater the radius, the more closely the surface formed by the chords approaches that of a true arc.
EDGE BLENDING ON CURVED WALL SERIES
The end result is a series of short chords rather than a smooth arc. Where curved walls once were formed from hand-hewn stone carved to fit a predetermined radius, radial walls of concrete masonry are usually formed from rectangular units of fixed shape and dimension. The use of concrete masonry in the design and construction of radial walls presents a unique challenge to the design professional. In addition, the relatively small unit size lends itself to unique applications, such as radial walls. The almost limitless variety of sizes, shapes, textures, colors and surface treatments has made concrete masonry one of the most versatile and sought after building materials today. You can create a curtain system like the images within a few clicks.Concrete masonry units are uniquely suited to distinctive aesthetically-pleasing architectural features. The easiest way would be to have a curtain system where you have multiple grid pattern options. But then you might as well create the whole curtain system, if not the whole project in AutoCAD or any other 3d program.
You can obviously make views of each segment and export them to AutoCAD and bring them back in as dwg’s and explode them. You can only pick the top or bottom lines. However, you can't pick accurately the section border of the blend at each height. It would have been much easier to be able to draw model lines at each panel height and connect these lines with other model lines to create the triangle shaped panel. And you can use the curtain panel as workplace to create blends or extrusion to create a custom panels.
You can use reference lines and lock them on the curtain grids and sweep a mullion profile. However, the curtain system do give you the work planes to create an in place curtain system. Also the mullions and panels don't clean up nicely. So the triangle panel consist then of two smaller triangles.
Furthermore, once you have created all blends and stack them up on each other and create a curtain system by face, some panels buckle at midpoint. And if the geometry have different profile sizes in section like the third image, then it is not possible with this method. Each blend has the height of one triangle segment. Scott's method works good, but extremely tedious.
