Learn how to create stirrups and experiment the difference between the Stirrup command and the offStirrup object.
Draw a 300mm, wide 450mm high rectangle and make a copy of it.
Open the AutoRebar Settings.
Check the Scale 1:10 option under the Scale tab.
Uncheck the Draw local dimensions option under the Dimensions tab.
Start the Stirrup command ; confirm 10 millimetres for the bar diameter and 30 millimetres for the concrete cover.
Click the top-left corner and the bottom-right corner of the rectangle to insert the stirrup in the concrete section.
Run the offStirrup command and repeat the sequence on the second rectangle.
Select the first stirrup and try to stretch the grip points. Notice that the second stirrups reacts differently
Double click the first stirrup and change the offset-to-cover and/or diameter properties. The stirrup shape is lost because it is made of a Rebar object bent into a stirrup shape.
Double click the second stirrup and change the offset-to-cover and/or diameter properties. Notice that the offStirrup object maintains the correct geometry.
Note: the Loop command allows the creation of circular stirrups.
