Creating Measures in Tabular Editor With C Sharp Scripts

Hi.  I have a problem and I could use some help.

 

I have a consulting firm that was charged with creating enterprise tabular models for big things like sales, inventory, etc.  They delivered models, but the measures in them need a lot of help.  For example, the sales model has approximately 2400 measures.  there is one base measure for "sales", "cost", etc. and then about 25 "time intelligence" calculations for MTD, QTD, YTD as well as compared to prior month, year, percent change from another period, etc.  On reviewing these measures, about 40% of them are wrong: they don't calculate correctly.  The money has run out, so they're not fixing anything anymore.  😖

 

I've written calculation groups/items to actually use real time intelligence for each.  I've verified that measures using these calculation group/items are correct.  But I have the problem of how to actually create/update measures in the data model itself because unfortunately I don't have the skill set to code in C sharp.  And I'm not correcting 2400 measures manually.

 

What I'm hoping someone can provide is (in order of preference):

1. Sample code to loop through a list of base measures and create the necessary time intelligence measures
2. Resources to educate a C sharp programmer on how this can be done
3. Any other assistance!
4. Resources on how I can quickly learn enough C sharp to do this myself 😕

Would appreciate any help that anyone could provide.
