I try to read all instance definitions from a 3dm file, but I am not sure about the approach I have to follow for the linked ones. Generally, I use the procedure described above
Instance References with Non-Uniform Scales.
However, it does not seem to fit the case of linked definitions, since the only information that is available is the source archive name.
Is there a way to force the api load them when reading a 3dm file? If not, what is the appropriate method in order to read such instance definitions?
No, you will need to use openNURBS to open the linked definition’s source archive and read the 3dm file yourself.
OK, thank you Dale.
