What is the purpose of the rounded edge?
Rounded corners are more effective for maps and diagrams because they allow our eyes to easily follow lines “as it suits better to the natural movement of the head and eyes respectively” [5]. Sharp corners throw your eyes off the path of the line so you end up experiencing abrupt pauses when the line changes direction.
What is a radius edge on lumber?
The cross section of a straight edge board has 90-degree angles at the corners. A radius edge board is made by rounding these sharp corners. After rounding, each edge has a straight center portion with a smooth quarter-circle at each end.
Why does CLS timber have rounded edges?
CLS calls for kiln dried, regularised sizes, planed (though not very smooth) on four sides with radiused edges. The radiused edges are to ease handling – causing fewer injuries from sharp corners and splinters.
Why does UI have rounded corners?
Rounded corners are perfect for grids, They help with a friendly interaction. They are space-saving. They draw attention to the content and not the component.
Why use rounded corners UI?
Shape. Buttons with rounded corners are easier on the eyes than a rectangle with sharp edges because they take less cognitive effort to visually process. Scientific research done on corners by the Barrow Neurological Institute found that the “perceived salience of a corner varies linearly with the angle of the corner.
Why are 2×4 not actually 2×4?
DIMENSIONAL LUMBER: In the past, when a timber was called a 2×4 [or “two-by-four”], it actually measured 2 inches by 4 inches. Because of this extra milling, a 2×4 no longer measures a full 2 inches by four inches. Instead, a 2×4 is really only 1 1/2″ by 3 1/2″.
What is the rounded edge of a board called?
Radius edge | Appearance Boards.
Why is construction lumber rounded?
During stacking, transport, unstacking, and handling, the rounded edges of construction lumber are less likely to be damaged. In a production mill, lumber is run at high speed through a planer that smooths the board faces and adds the slight round-over on the edges all in one pass.
Why does 4X2 have rounded edges?
2×4 have rounded edges as it’s very beneficial to the wood itself and those working with it. They reduce the number of injuries like unwanted splinters during the handling and manufacturing process and also ensure that the lumber stays looking its best all throughout until the customer sees it.
Why do we ease the edges of construction lumber?
During stacking, transport, unstacking, and handling, the rounded edges of construction lumber are less likely to be damaged. This is the main reason we ease the edges of tabletops, shelves, and cabinet sides. But of all the reasons, this one seems most likely to be merely an added benefit.
Why do studs have rounded edges?
A rounded edge lessens drywall damage, even when studs are not perfectly square. The problem with this being the “original” reason for easing the edges of lumber is that mills were rounding edges on lumber long before drywall became transcendent, replacing plaster and lath.
What are the advantages of a rounded edge on wood?
Rounded Edges Make Boards Easier to Handle Smoother, rounded edges are more suited for bulk handling. When selecting multiple 2x4s from the lumber yard, the slightly rounded edges make it easier to pull individual pieces from the stack. Boards with rounded edges are also easier to slide into the back of a truck.
Do rounded edges on timbers damage drywall?
Framed walls with slightly out-of-square timbers would present a sharp edge when the face of the lumber is not perfectly square to the plane of the wall, so drywall could be damaged during installation. A rounded edge lessens drywall damage, even when studs are not perfectly square.
