Stop Case 1/Stop Case 2 Chamfer

Untitled.png

I'm trying to igure out a way to create this chamfer without doing a sweep. Please see image.

 

I need a chamfer on the edge, between the two points. I can do stop at reference, but can't seem to select more than one point on which to stop. As you see, I need it between two points.

 

I can't seem to find the option for stop cases, either.

 

I'm new to Creo Elements/ Pro E 5.0, but have seven years modeling experience. Thanks in advance for your assistance!

    Re: Stop Case 1/Stop Case 2 Chamfer

    I haven't seen the chamfer command do that before, but if a round would serve your purpose you can use that blue curve on your part as a guide for the round.  See "thru curve" option within round command.

     

    But, a sweep would be the better choice.  However, don't use "Sweep" use "Variable Section Sweep".  It will give you what you want without the cascading menus.  Variable Section Sweep doesn't mean that you have to vary the section.  It just an option.

     

    That's a good looking background color.  What are the RGB values?

    Hi

    Do you want to chamfer with in certain limits?

    Check the following

    This may help you

    There might be some more options

    (I rarely use these options)

    For the end geometry you could create a boundary blend or a filled sketch if you still want to work without sweeps.

    Re: Stop Case 1/Stop Case 2 Chamfer

    When I try this, the box where you select the stops is greyed out. I also can't add any transitions. Did I miss something?

     

    Thanks

    Re: Stop Case 1/Stop Case 2 Chamfer

    Sounds like the simplest solution os to use a swept cut.  No need for a VSS on simple geometry and with a simple trajectory like this.  And, it appears a swept cut would give you the proper cutter geometry anyway, so why do anything else?  Why the hesitation to use a sweep Kris?

        Don't get hung up on whether things are actually "chamfers" or "rounds".  You can always rename the feature and call it what you want.  The key thing is getting the geometry right.  THAT'S the only thing that actually matters.  And in this case, it isn't really a "chamfer" anyways, it's the result of an interpolated toolpath (sweep) using a chamfer cutting tool, is it not? 

         

        There are usually a couple of different ways to do things in Pro/E, the simplest that actually gets the geometry needed is always the best option.

         

        Good luck!

        Hi Kris

         

        Chamfer at stop reference has certain limitations

         

        But you can select Plane instead of point for defining Stop Reference( As I have tried in the following image)

        This will give you some useful results

        I would not say this is a very good solution; But I want to just share some of the Creo/Pro-Engineers Features.

         

        I hope you will find it interesting

         

        Regards

    Re: Stop Case 1/Stop Case 2 Chamfer

    Ok Kris, here's one for you:  I had a case where I wanted to stop a round on both sides of a part (mirror image) at a face.  I went thru all the different options of the stop cases, realized I'd have to do it as surfaces and do a bunch of monkeying around before I could use a solidify/cut to remove the material, and decided to just sweep a surface, put a fill surface cap on it at the vertical surface, and then remove the material with the solidify/cut.  It ended up being 7 features total as opposed to being 2 IF I could have gotten the rounds to work as solid rounds, but I couldn't and stopped wasting time trying.  Sometimes, it's best to just use what works and not Get hung up on whether it's "technically" a "round" feature or not.  Get it done, and move on.  As I've always said, a good Pro/E user knows the commands.  A great user knows the Pro/WORKAROUNDS (and is Pro/FICIENT in the use of the Pro/FANITY module)!
