Hello, Mat again
Have you already solve this problem?
I applied the code you wrote to my Creo, then it works.
(dont have to select its reference)
which version of Creo/ProE do you use?
weblink can't insert feature directly.
API reference says "pfcSolid.CreateFeature is Not implemented in the current release".
and unfortunately, PTC won't enhance pfcAPI including weblink any more.
So the only way you can insert the feature is UDF(or using macro)
