SOLVED Motion Study Results Exporting to CVS file

JS 2021-04-09

‌

Hi, I am a part of Clemson BAJA SAE. I am designing a rear suspension and I need to analyze graphs like camber gain and wheel paths. Thus I want to export the result plots to a CVS file with a macro. I can not do this by hand since my plan is to run an algorithm that continues to update and improve the suspension design based on the results of the motion study.

boolstatus = swCosmosMotionStudyResults.ExportCSVFile(plotFeatures(2), "C:\Users\Matt\Desktop\Baja 2019-2020\Programming_For_Design\Trace Path1.csv")

All I need is for this line to work. It does not throw an error, but it does not export the file. I believe I correctly got the plot features because the size of the array is 3. However, when accessing GetTypeName I get this run time error. This makes me scratch my head because a type mismatch error was not thrown when initializing plotFeatures as an IFeature object and GetTypeName is a method of the IFeature object, which makes me think plotFeatures is corrupted in some way.

Thank you for any help!!

SOLVED

I pretty much figured it out with a little workaround, but still, the method achieves all my goals. For some reason, only actual plots that have X-values and Y-Values can be used in the ExportCSVFile(...) function. Thus to achieve a CVS file with the wheel trace path. I added three linear displacement result plots to the same plot (Plot6). The full file path is needed including the new file name. This macro can run even with the plots hidden, thus can be used iteratively in my new genetic algorithm.

'PLOT FEATURE MUST BE AN ACTUAL PLOT, EXPORTING TRACE PATHS DID NOT WORK ==> Angular Displacement, Linear Displacement, and Etc can work

Debug.Print "it worked: " & boolstatus
