I am workin on a bit of code that would automate the creation of O-rings, but i am stuck on creating the revolved feature, and would appreciate any help. When running the code it works all the way to the model creation, then i get an error message. I am kind of new to SE automation so any suggestions are welcome.



The code is below:

Imports System.Runtime.InteropServices
Module Module1

    Sub Main()
        Dim objApplication As SolidEdgeFramework.Application = Nothing
        Dim objDocuments As SolidEdgeFramework.Documents = Nothing

Ah, you were so close!


Dim objAxes As SolidEdgePart.RefAxes = Nothing

 should be


Dim objAxis As SolidEdgePart.RefAxis = Nothing

Notice that it's "RefAxis", not "RefAxes"...


FYI, I referenced the SolidEdgeCommunity / Samples on GitHub to see working code to compare against. Specifically, I looked at the PartHerlp.vb class of the ApiDemos project and searched for keyword SetAxisOfRevolution.


I would also like to mention that all of the


If Not (objX Is Nothing) Then
	objX = Nothing
End If

are not necesesary in this particular scenario. You have a console app that executes the code then exits immediately. The Runtime Callable Wrappers (RCW) live in a single AppDomain and get released automatically when the AppDomain is unloaded, which in this case is when the application exits.

Re: FiniteRevolvedProtrusion

Thank you for your help, and thank you even more for the links. The examples will help me learn a lot. I am kind of a copy/paste programmer since i didn't have any serious programming lessons beyond for loops, so i didn' really understand what ReleaseComObject does so i left it. I know it's a bad way to build proframs, but i work with what i have.

Anyway thanks for the help.
