Unlike other rebar families, spiral rebar is multi-planar and cannot be edited at the family level. However, you can scale and rotate individual instances.
Adjusting the Height of Spiral Rebar
To change the length of the spiral, use the triangle shape controls at the top and base of the rebar spiral. Drag the arrows accordingly to lengthen or shorten the spiral.
These controls do not stretch the spiral. They add the proportionate number of coils required to maintain the specified height of the spiral rebar.
Scaling the Diameter of Spiral Rebar
To scale the width of the spiral rebar coils, locate the scaling control opposite the rotation control which is at the end of the actual rebar coil. Drag the control to adjust the diameter of the spiral.
Rotating Spiral Rebar
The positioning of the spiral rebar can be rotated to align the end of the rebar as needed. Drag the rotation control at the end of the top rebar coil to rotate the position of the end of the rebar.
