Question

VB API Access to PTC Creo Model/PRT Annotations

I'd like to access, through code/programmatically a *.prt model's Annotations (e.g. Symbols, Datums, Notes, Dimensions). These would be the objects that are, in PTC Creo 10.x, in the model tree -> Design Items > Anotations. Is this possible through the base license of Creo (i.e. in Visual Basic)? The annotation objects seem like they might be accessible through details (drawings), but I cannot find their equivalents in the Model/PRT file. Could someone point me in the right direction?

PFC APIs (Creo Foundation Class APIs): These APIs are provided free of charge for Creo Parametric users and support Visual Basic. However, these APIs offer limited functionality, and verification is required, particularly regarding full access to all elements of 3D annotations (MBD). The PFC APIs are primarily used for simple applications and for manipulating core Creo parts, assemblies, and drawings.

Although VB is limited, you can modify the model with dimension values, change parameters, and create models.
If you visit my blog, you can get various VBA sample codes. : https://tool-2020.tistory.com/
