I am trying to create a sketch inside of a part file that references a SKELETON part file. I need the new sketch to reference lines and geometry from the skeleton part file. Both of these files are inside of the same assembly. I am currently using Creo 2.0.
Any help would be greatly appreciated.
What you're wanting is pretty standard. As Mahesh said, you activate the part where you want to create the sketch. Create the sketch as usual referencing any geometry. Are you getting errors or are you not getting results? One thing you may want to be aware of is the display of inactive components in the assembly. If you want normal display of them, set config option dim_inactive_components to "never".
Also, make sure that config option default_ext_ref_scope is not prohibiting the user of external references.
