FS get and set properties

graham_lock

Hi all,

I'm simply trying to get / set the name property on parts.

If I try reading the name property I get the following error:

@getProperty: Cannot get properties during feature regeneration

If I try to set the name property I get the following error:

Precondition of setProperty failed (definition.entities is Query)

I would have expected this to be simple so I'm probably missing something.

Any help appreciated.

Thank you.

If you haven't done so, I'd take the FeatureSciript course in the Learning Center.

Also, here's a simple custom feature that renames parts.  Take a look at its code.

BTW, what may not be obvious is that you can't get properties in a feature, only set them. Properties are often set after feature regeneration, so, while the feature is being executed, you wouldn't be guaranteed to get the right value. getProperty will only work in custom part property code and custom table code.

If you just want to store metadata on parts, use attributes.

Thank you, I'll look at the course and the sample.
