Mass Accuracy in iLogic

[Anonymous]

Hello,

 I recently asked for help to set the mass calculation accuracy to 'VeryHigh' when doing calculations in iLogic.

I asked for the iLogic equivalent to the VBA term:

  ' Set the accuracy to VeryHigh.
      oMassProps.Accuracy = k_VeryHigh

and was provided with: 

     oMassProps.Accuracy = 24580 'k_VeryHigh=24580      

However, I believe that the value 24580 is actually equivalent to k_Medium.

Can somebody please confirm the iLogic equivalent value of k_VeryHigh.

Many Thanks,

 Nick

p.s.

From the VBA object browser:
k_VeryHigh = 24580
k_High = 24579
k_Medium = 24578
k_Low = 24577
k_None = 24581

To be more sure, you could use:

Imports Inventor.MassPropertiesAccuracyEnum
oMassProps.Accuracy = k_VeryHigh

iLogic uses the exact same methods as VBA 99% of the time, sometimes with a catch. In this case all you needed was the imports statement. VBA will apply the import automatically, where iLogic needs it explicitly stated.

Hi Mike,

 Many thanks for the swift response.

I have my suspicions that iLogic does not respond to the numerical input, or there is a slight programming error, as through my (and others) testing, using 24580 only achieves Medium accuracy.

Many thanks for the alternative method, it seems a more robust way of achieving what I am trying to do.

Having tested it, my model is now achieving the accuracy I require, and is accomplishing it in only 75 iterations, whereas yesterday it was taking over 350.

Having struggled with this project for a month now, two weeks of which solely on trying to resolve the issues caused by the mass inaccuracy, I can safely say you are my saviour.  Have some kudos.

Many thanks again,

  Nick

Honestly, I didn't expect it to work any differently for you. I'm glad it did though.
