I got several problems in my project:
1.I have several elbows less than 5 degree in pipelines and got error "Bend angle specified for the bend element is within 5 degree of bend far end point, either use the bend far end point or move the specified node more than 5 degree away from the end point"
The problem is , the piping layout will be changed if I move the node. And a gap will be generated between the pipes if I connenct the skewed pipes together without a BEND.
Is it possible to build the elbow in CAESAR II less than 5 degree?
2. I have 384 element in the pipelines. ALLOWABLE STRESS button is actived for every element. Can you recommend a convenient way to active the button? I have to press button one element by another. it can't be propagated.
3.I have 2 uniformal Loads, snow load (lb/in)and seismic load (g-value). I can't input the two uniformal loads at the same time because they have different unit. What can I do for uniformal loads with different unit?

Any advices will be appreciated greatly!
