h2. Must tendons which are modeled as loads be assigned to group ALL?

*Extended Question:* During [staged construction|kb:Staged construction], when tendons are modeled as loads, must load be applied to tendons which are grouped using the group ALL feature? Load does not seem to transfer to individual tendons or tendons within the standard group.

*Answer:* When [tendons|kb:Tendon] are modeled as loads, tendons do not exist within the model as objects ([joints|kb:Joint], [frames|kb:Frame], [shells|kb:Shell], [solids|kb:Solid], etc.). As a result, load must be applied to groups which contain these entities. The group ALL feature is useful for this purpose.

Three options are available for [modeling|kb:Modeling techniques] tendons:

# Model tendons as objects.
\\
\\
# Determine which objects will be loaded by stressed tendons, then create groups to control loading.
\\
\\
# Apply tendon loads in separate [load patterns|kb:Load pattern] which are created for each construction stage. Then for a given stage, apply these load patterns to objects within group ALL.
