CAST Design Tool | Strut-and-Tie Method (STM) | Q & A about STM

1.	Can CAST be used to design statically indeterminate strut-and-tie models?	Answer
2.	Can CAST handle multiple loading cases in one model?	Answer
3.	What are the differences between Outer Boundary and Inner Boundary? When and where are they necessary?	Answer
4.	What is a Stabilizer? Why and when is it necessary?	Answer
5.	Can STM Element or STM Node ID labels be changed?	Answer
6.	When creating the strut-and-tie model, should I create STM Nodes first before create the STM Elements?	Answer
7.	Why are most of the buttons in the left toolbar disabled? Are they not available yet?	Answer
8.	Some of the menus are labeled (NA) at the end of the phrases. What does this mean?	Answer
9.	I obtained error messages during the truss analysis. What should I do?	Answer
10.	Is there a way to overwrite the default values used in CAST?	Answer
11.	Can we customize CAST window?	Answer
12.	Does CAST support color printers?	Answer
13.	What are Stress Ratio, fc' Ratio, and Beta Ratio? Which one should I use for design acceptance?	Answer
14.	How are STM Node shapes constructed in CAST?	Answer
15.	I want to capture image displayed on some dialog boxes, such as the Define Non-Prestressed Reinforcement Tie Types and Show STM Node Info dialog boxes, and then paste it in my design report. I also want to copy and paste the values shown in dialog boxes' text boxes. Can I do that?	Answer
16.	I was trying to check the Stress Ratios, fc' Ratios, and Beta Ratios in the struts and nodes, but I could not get the values. All were labeled NA after I ran analysis. Did I miss something when defining the properties?	Answer
17.	I tried to remove the Outer Boundary, but I could not select and delete it. Is there a way to remove it?	Answer
18.	Where can I obtain examples of CAST input files?	Answer
19.	Where can I go to get more information about the CAST Design Tool?	Answer
20.	What if my questions are not listed here?	Answer
