Changing the properties of a custom parameter

[JorisSteurs1246]

I need to change the properties of the custom parameter G_L by unchecking the leading and trailing and units string checkbox and also presision set to 1.1 ( screenshot attached)

I have to do this for about 250 files, so I'm not eager to do this manual.

Any suggestions, iLogic maybe ???

Thanks

I know already that with design assistant I can copy over my modifyed custom property to other files , but this will also copy over the value of the modifyed custom property. In my parts the value is linked to an exported parameter , also called G_L and the values should stay in sync. Uncheck and check again the export box  in tthe parameter UI will bring them in sync again but this will make the the custom Iproperty settings back to defaults with its trailing and leading zeros etc that will bring me again to square one.

Yes, it is quite possible with iLogic

Yes, if you wish to format the parameter, it must remain exposed as property/marked for export.

Yes, there are other posts that have all of the information you need elsewhere on the forums.

Been looking around quite some time and I find many posts around custom Iprops but they only talk about creating them and setting their value but never about setting the properties of the custom Iprop.

If the Custom iProp is just the exported parameter, then it takes the format that you set for the parameter in the parameter window.

If you want to have the format of the custom iProp and Parameter be different, you need to find yourself a genie in a bottle..... or create ANOTHER parameter that you can format and export as desired.

Thanks for guiding me around Justin, 

By accident I think I just found a genie in a bottle under this post.

As good as I understand it they manage to format the custom properties in this code.

I think I might find most of what I need there  to puzzle my thing together.
