add closed sketch loops to existing feature

[ilotey]

is there a way to use vb to add closed sketch loops to an existing feature?

I am trying to create a parametric template for a fan guard assembly, complete with drawings.

I am using an arrangement of circles defined using some linear sketch patterns as the cross-section of a revolved feature.  Using ilogic/vb, I want to automate the number and spacing of items in the linear pattern, and then update the loops selected for the revolved feature.

I have found code on this forum (courtesy of Curtis Waguespack) that I can use to select all closed loops and create a feature.  I can apply this code to create a NEW revolved feature, but I haven't been able to figure out how to use it to UPDATE an existing feature.

I need the feature to UPDATE rather than create new to maintain links in my assemblies and drawings.

Any help is appreciated.

got it.

Set oRevolve = oCompDef.Features.RevolveFeatures.Item("revFaceWires") 'get the feature
Set oSketch = oRevolve.Profile.Parent 'get the sketch
oRevolve.Profile.Parent.Edit 'edit the sketch
Set oProfile = oSketch.Profiles.AddForSolid 'get the profile loops and save to oProfile
ThisApplication.CommandManager.ControlDefinitions.Item("FinishSketch").Execute 'exit the sketch edit
oRevolve.Profile = oProfile 'update the profile definition for oRevolve
oPartDoc.Update 'update the doc

part updates, drawing doesn't break.  YAY!
