Draft Surface function enhancement.

Direct selection in single surfaces is blocked. We can not select single surface without its feature consideration. We need to use Exclude Loops to solve situation. Practically when I select surface for draft Creo takes all surfaces done with that features. (Example - Quilt Solidify). That's very bad!!!!!

I'm no sure what you are talking about.  When I create a draft feature in Creo 2, it won't let me select a 'feature' to draft, I must select surfaces.  Yes, I can select 'intent surfaces' or an entire 'quilt', but by default it selects one surface at a time.

It's ben that way for as long as I've used Pro/E, back to rev. 16.

It is easy do a solid parallelogram with 20x20 mm with thickness 2 mm. Exrude cilinder (diameter 10 mm) quilt with capped ends in the middle of parallelogram. Cilinder must be extruded in two directions for 10 mm. Solidify. Try to draft cilinder surfaces.

In your JPG it says it is selecting individual surfaces, not the feature.  You cannot draft the tangent half circles separately, this is more about geometry than about Creo.

If, however, you are talking about the fact that the surface ID is the same above and below your rectangle that bisects the cylinder, this is easily handled in the options tab of the draft featureby selecting 'loops' of given surfaces to exclude from the draft.

The issue is that Proe / Creo considers bolf halves of the extruded cylinder to be teh same surface ID because they were created in the same feature with the same sketch entity.  you could also create the sketch and then use that sketch to make two extrudes, one up and one down.  Then you'd have separate surfaces to draft.  Or use the exclude loops.

I don't want more use loops. It's boring and I used I-Deas and UG from 1998. Last two work perfectly without loops.
