Rounds do not complete in Creo

[jferguson4]

I am finding that some edges on a simple rectilinear model will accept a round of say .125 radius on a 4 inch side, show the geometry but not remove the model material which would be gone if the round completed.

I've tried starting with different simple models and it fails on some and not others. There may be a common origin of the trick edges like they are edges created by an extrude.  I haven't gotten to sorting this out.

I've been running Creo and Pro/e for a very long time and have never encountered this before.  

What would you look at assuming this isn't a bug?

If this query is not posted in the correct area here, let me know.

More information would be needed. What version of Creo are you running? Post some examples or at least pictures of the issues you are facing.

[jferguson4]

I'm using Creo 9 on an HP 8100 Elite with a Nvidia 1070GX graphic card.  I should be clear that round works most, but not all of the time.

As I think I said above,. in 32 years using Pro/E and then Creo, I've never had this happen before with a simple round.

I could add the pRT file if that would help.

Hi,

please do it.

Your screenshot looks like something that happens when you use the "surface" option (instead of "solid") for the attachment:

I was thinking the same thing. I'm on Creo 9 and have inexplicably had the surface option come up as the default on some occasions. I've never figured out why, always figured I must have mistakenly fumble-fingered something wrong.

HI Guys,

I made another model like the one with this problem and everything worked.  This one seems to be locked. It will accept edits and keep the edit information but not change the model.  extrusions do not work either to add or remove material.  So my question now is if there is some way a model can be copied - and I did copy it such that it can collect edits but not act on them.  

I don't know how the rest of you work, but I usually develop 2 or 3 different parts when I'm designing usually by saving to a new name so that I can go back more easily if i don't like where I've come to.

So simple question. If you copy a part, might it be locked, or might the original somehow become locked.  If this can happen, is there a way to unlock the "locked" part?

You'll get much better answers if you upload the file.

You can't "lock" a file to make it so it will only do surface rounds

[jferguson4]

I think I've found the problem.  This part has 2 bodies, see screendump.  I don't have any other files with this condition so I'm assuming that this is where the problem is.  What do you think?

I need to get sharp[ on this.

[jferguson4]

here's the part

@jferguson4 

The part didn't attach. Easiest way is to zip it. 

[jferguson4]

how about this?  while we're at it, has anyone reading this ever dived into the "bodies" section?

Thanks much.  I suffer to some degree by not using Creo every day.  I'm retired and doing what could probably be construed to be hobby projects.  I do most of my model iteration in OnShape because its drawing module is easier for me to use, and most of these projects get iterated to death through 3D prints.  But when it comes to cutting metal, it's back to Creo which maybe happens 5 or 6 times a year and I'm confronted with improvements to Creo that I may not have encountered the last time I did something.  

Thanks to everyone who helped in this forensic exercise.

Hi,

 (Note: I suppressed some Extrude features)

Copy 1 feature creates Body 2 as a copy of Body 1.

Round 1 & Round 2 features use references from Copy 1 feature (from Body 2).

Rounded geometry is hidden in Body 1.

If you hide Body 1 you will see rounded geometry.

[jferguson4]

Thanks much Martin.  I need to read up on multi-bodies.  It was a new feature that snuck up on me.
