From flat data sheet to curved model. How

[stevenqneuk]

Is there anyone out there who can solve my problem? I have a filler neck for a car radiator that I need to model in Pro-E. I also have the data sheet for the filler neck. Sounds easy so far. The problem is, the data sheet shows part of the filler neck in flat form but its really curved. The three pics below show the real part, the data sheet and what I have in Pro-E so far (the highlighted edge is were the problem is). Thanks to anyone who can help

For the part that slopes down, I would use a Variable Section Sweep with a trajpar relation. Find out the starting height and the ending height and do a search in the forum for "trajpar".

Trya "spinal bend"


Dunno why people keep jumping on VSSs, have been on Pro since '91 and can't think of any occasion I've used one of these..

odd
i would have used "toroidal bend"

then toroidal bend

ive tried both vss and this way.
toroidal bend is definatly the way to go. much more direct, and very easy to modify

unfortunately the toroidal bend help is pretty lame @ best. i suggest d/ling the tyre models and learning how to use it. if u have not used this feature before

Hello,

Here is how I did this.



1.Revolved wall

2.Edge rip

3.Regular rip

4.Regular unbend

5.Cut

6.Bend back



Hope you find it useful.

I guess there's more than one way to skin a cat. dougr, you should take a new look at VSS - there's been a lot of changes sincethe horse & buggy days of CAD.It seems especially in WF, easier than ever.(were you on hiatus or something?)

Looks like your right Mgnt8. I sent the same info to a Pro-E trainer and she recommended I create a sketch on an offset DTM plane then use project or wrap to place the sketch onto the curve and use this to extrude or cut into the surface.


Maybe the subject should have been "how many different ways can this be done?" lol. Anyway, I have learned loads of new modeling techniques over the last couple of days, keep your sugestions comming

Why don't you create the rim in the flat state as the first feature then roll it up in sheet metal and add the neck?



If done this way you can probably do it in 3 simple features

best regards

 

[great_cheetah]

i think ralbu just demonstrated a toroidal bend in sheetmetal

 

[Dell_Boy]

I have just tested my suggestion and yes it does work though the revolved wall is done as an unattached wall however it can be merged for a grand total of four SIMPLE features and not a VSS or toroidal bend in sight

It is possible to do it in three simple features with no unattached walls in any version of Pro/E but you have to twist it's arm a little to accomplish this.
