Flat pattern sheet metal drawing

SOLVED

Re: Flat pattern sheet metal drawing

With the flat pattern feature you are not able to but in a Bend Back feature after it. So instead of supressing the bend back feature, you supress the flat pattern. You still get the use of the parameters that the flat pattern creates. You try and use a combined state to see the different views.

Re: Flat pattern sheet metal drawing

I think view states had a hand in this. I will see later if I can reproduce this.

Re: Flat pattern sheet metal drawing

l´m really sorry, but don´t understand yours replies Andrew Hermanson and Antonius Dirriwachter. Could you make a screenshot/picture what do you exactly mean?

If l use BEND BACK it´s everytime push above flat pattern and regeneration of bend back is failed... it´s logicaly...but try to describe what do you mean with your previous replies. Thanks you in advice...

Re: Flat pattern sheet metal drawing

I understand the problem you are having. I am not sure how I achieved the bend back after the flat pattern in the previous example. I will see if I can replicate the process and I will post.

I did look further into what I did for the dual states on the drawing. I did not use family tables but did use view states.

I will further investigate this and document it so that others can use the information. Please give me a few days to get this resolved to a satisfactory state. I will update this post if I find anything relevant in the meantime.

Re: Flat pattern sheet metal drawing

I just confirmed it -can- be done but it doesn't make sense why; and it could well be unstable in case one tries to make changes. But: I used a simplified rep state to create the bend back while the flat pattern was excluded. Of course it failed because there was nothing to bend back. I next excluded the bend back from the new rep as well and regen allowed it. Saved the rep and went back to the master and the bend back remained below the flat pattern.

I then removed the added simplified rep; saved; erased all displayed; and reopened. No issues, no errors on regen. PTC really needs to take a look at this.

I need to think through how to best use this <snip> workaround.

Again, form features is a different challenge but we can also flatten forms with reps or family tables.

It´s ABSOLUTLY perfect! Thanks you very much! Below is my solve (inspirated with your help) of sheetmetal unbend states in Creo 2.0.

You are very welcome

Re: Flat pattern sheet metal drawing

Can someone tell me how to bend unbend pipe in Sheetmetel.

Re: Flat pattern sheet metal drawing

Tubing is not sheetmetal. You cannot use sheetmetal to bend or unbend tubing.
