Draw a line pattern reinforcing shape by clicking the Draw menu > Draw Reinforcing Shape > Line Pattern command or by clicking the associated toolbar button, . Following are the shape properties associated with line pattern reinforcing shapes.

Type: This item is Line to identify the type of reinforcing shape. It is not editable by the user.

Material: The material property associated with the reinforcing steel. This can be any material property with a Concrete design type. Section Designer uses the steel yield stress from the material property.

X1: The Section Designer X coordinate of the first drawn end point of the line pattern reinforcing.

Y1: The Section Designer Y coordinate of the first drawn end point of the line pattern reinforcing.

X2: The Section Designer X coordinate of the second drawn end point of the line pattern reinforcing.

Y2: The Section Designer Y coordinate of the second drawn end point of the line pattern reinforcing.

Bar Spacing: The specified (not necessarily actual) center to center spacing of bars along the specified line. Section Designer calculates the required number of bars by dividing the length of the line by the specified bar spacing and adding one to the result. Usually this calculation leaves some fraction of a bar left over. If that fraction is greater than 0.1 then Section Designer rounds the number of bars up; otherwise it rounds the number of bars down. Once Section Designer knows the final number of bars to be used it calculates the final bar spacing by dividing the length of the line by the final number of bars minus one.

Bar Size: The size of all of the reinforcing bars along the specified line.

End Bars: The value of this item is either Yes or No. Setting it to Yes means that there are bars at the end points of the specified line. If this item is set to No then the first bar starts one space in from the end point of the line. The sketch below illustrates line pattern reinforcing with and without end bars.
