API - Difference between methods

cool.stuff — Thu, 04 Jan 2024 14:55:03 GMT

Hi!

I've been reading about API methods to get bar forces and I have not been able to find the explanation anywhere.

What is the difference, in practice, between bar forces and BarForceServer.ValueEx and BarForceServer.Value?

Many thanks in advance

hi @cool.stuff

'ValueEx' is used to extract forces in case of code combinations or moving loads and 'Value' in case of simple cases or manual combinations

Dim BFD as IRobotBarForceData Dim bar_num As long, case_num As long, case_cmpnt As long, point As double Set BarForceServer = RobApp.Project.Structure.Results.Bars.Forces With BarForceServer set BFD = .ValueEx(bar_num, case_num, case_cmpnt, point) ' Code combination set BFD = .Value(Value(bar_num, case_num, point) ' Others End with

see getting internal forces from RSA to XL (API) and 866-867 of Robot Object Model pdf file.

Best Regards
