Sheet metal question 4

[eex23]

Hello,

look at the attached prt file (its NX7). We got some parasolids with sheet metal parts. These parts were created in NX, prior to NX7. I am trying to recreate some of them, but it seems impossible to get desired things to me. Take a look at the corners: to the left side I already added "move face" feature to show what I am getting using standart sheet metal funkctions. Right side corner is the one I want to get. So how has been it done using standart sheet metal functions?

Thanks.

Hi,
Is this what you want to get?

no. Look at the attached picture. In that case the gaps are minimal.

From the looks of it, and someone might have to correct me if I am wrong, I haven't used NX 7 Sheet metal, but I believe that NX7.5 Sheet Metal is very similar. So if this is to be assumed correct, and you are looking to create an overhang bend like the right side of the part that you uploaded. Depending on how you create the flanges and the original Base tab is going to depict how you would do this.

If you draw out the entire Flat Pattern, and then added bends where they should be located this would be one way of achieving this.
1) Create a Sketch that matches the Flat Pattern
2) Apply Bends at proper locations.

If you created a Single Base then added Bent Flanges you would need to add additional information.
1) Create Base Tab
2) Create Side Flanges
a) These should be created square we will add to them in a later step.

3) Create Angled Flange.
a) There is an option so that you can edit the sketch Profile when you are in the Tab and Flange Commands, Edit the angled flange so that it has the step that you want and then have it fall in the middle of the Side flanges.

4) Create Secondary type Base tab.
a) You will create one for each side. Draw the profile in the desired style and you should end up with what you have shown.

Hi eex23,

Use Closed corner function and set treatment as open, overlap closed, gap 0. Try this.

Hi,
Sorry i don't have NX7 with me but i am attaching NX8 (but the method is quite straight forward and can be easily done in any previuos NX version)sheet metal part with me.I just created a tab and then accompolished the same using only two Flanges (edit the flange sketch to get the desired result).
I am attaching a image also.(zip file).Do let me know if i am missing your point.

I guess the question I have to ask is, WHY ARE YOU STILL RUNNING NX 7.0? Didn't you get the memo?

(tongue in cheek)

John, the memo was received but management has decided to delay the upgrade until we have time to do the upgrade. The upgrade must be coordianted with the PDM tool which requires a 5 month test and prove out to do its upgrade. Then we need to arrange for user update training and IT decided to move us to 64-bit servers, delaying the PDM update even more.

(Back to normal Friday business)


While I did the above as a joke, I will tell you that the coordination of CAD and PDM is not always understood by all parties. Dealing with PTC and my Windchill upgrade, I had an email from a senior Windchill developer on an issue. He was shocked when I told him that to go to the latest build of Windchill 10, I had to use a newer build of Wildfire 4 than we currently had running, and I was only 1 build behind the latest. Not everyone reads the software compatibility matricies. And to top it off, the latest build of Wildifre 4 was only available by download, no CDs sent by PTC. Downloaded ZIP files are blocked by our corporate firewall, so I had to download and burn 10 CDs at home on my own time in order to upgrade Wildfrie 4.

Thank you all for your help. Actualy my problem was solved using closed corner function.

to John Baker: no, we havent recieved any memo about NX7. What kind of memo we should recieve from our seller?
I will ask them for it.

That was a bit of a joke as there was no actual 'memo', but when NX 7.0 was released it was done on Windows ONLY becasue NX 7.5 was being released shortly thereafter and we advised our customers to that effect and 'suggested' that unless there was some overriding need to upgrade at that time that people should wait for NX 7.5. Also there was only a single MR for NX 7.0 and very few MP's as most people got the 'message' and waited for NX 7.5 (or upgraded from NX 7.0 as soon as NX 7.5 was released). Note that while we're still issuing critical MP's for NX 7.5 there is absolutely nothing being done with NX 7.0.

In that case we got the "memo"
As far as I know our company also wanted upgrade from NX4 to NX7.5, but there were some issues with our grip programs. NX7 was also chosen for the possibility to use old mating conditions. Actually we have installed NX8 for testing purposes, and being sincere, I cant get used with new assembly constraints :/ New assembly constraints lets you to make assembly faster, but it becomes pain if you try to edit something.
