How to Convert Known Dimensions to Reference Dimensions in Creo

I am using Creo Parametric 11.0.1.1 and facing an issue with dimensions created from assembly references.

While creating a new part within an assembly, I use geometry from an existing housing as an external reference. I then create an offset from that referenced geometry to define the new part. The resulting geometry is created as a composite curve.

When I create a radius dimension on an arc of this referenced composite curve, Creo creates it as a known dimension with the kd# prefix. This dimension cannot be retrieved in the drawing using Show Model Annotations.

I tried changing the following configuration option:

sketcher_known_dim_on_ref_ent no

However, Creo does not retain the value as no. After I set it to no, it changes back to yes, and the dimensions continue to be created as known dimensions.

I also tried recreating the dimension after changing the configuration option, but the result is the same.

The selected geometry is identified as:

Arc of Composite Curve (Reference)

Could this be a bug in Creo Parametric 11.0.1.1?

I would like to know:

• Why does sketcher_known_dim_on_ref_ent automatically return to yes after setting it to no?

• Is this a known issue or limitation in Creo 11.0.1.1?

• Is the no value unsupported or ignored for referenced composite curves?

• Is there another configuration setting or modelling method to create a reference dimension instead of a known dimension?

• Is there any way to retrieve known dimensions in a drawing using Show Model Annotations?

Any guidance or confirmation from users experiencing the same issue would be appreciated.
