Who has succesfully used the Warp feature

[Huug]

When Wildfire came out, one of the new features was the Warp feature.
I have seen lots of demo's, and the help section shows some examplesas well.


As a true parametric enthousiastI couldn't imagine any need for such usesless freeform dragging, *but* now I have finally modelled a part where some warping can be usefull.

This small cap will be made of TPE (rubber) and the current flat state is how it will be moulded. WhatI like to do now, for visual purposes, is to close this cap using the bend option within the warp feature. But no mather whatI try, I don't succeed. The warp features responds very slow, adding dimensions in the option box doesn't make any sense, and (un)checking any boxes helps either. There is alsoa list that allows you to add several warps, but that makes just some more mess of the part.


So who of you did succesfully made use of this warp feature? And who find it easy to work with? Who has an example of how to use it?


Will I upload this part so you guys can give it a try? It is made in Wilfire 2.0

Warp is recommended in cases when you import a part and want to make changes to it. Remember neither warp feature is truly parametric nor the imported part.


So if we define Modeling purposes :

1. 
   <LI>Modeling for Analysis (parametricity very impotant and warp not recommended)</LI>
   <LI>Mdeling for Manufacturing(Parametricity useful as well if the project is subject to ECOs and ECNs and hence warp not recommended)</LI>
   <LI>Modeling for animation and presentaion (warp recommended)</LI>

We have used warp successfully in the third case and in cases where we need to make changes to imported parts.


I hope this info is useful.


Comments are welcome.

I use warp feature in case where I must put already created complicated

I don't think the Bend operation will bend your part far enough the wayyou want it. AFAIK Warp is for more slight deformations. Instead you might try aspinal bend

 

[Huug]

Deforming this part was for presentation purposes only.
The unfold version is yet released and moulds are created as we speak.

But spinal bend is the way to go! Thanks mgnt8!
It is always nice to learn some functionalityafter 10 years behind Pro/E!

And this is my expirience of Warping:

DID YOU SEND THOSE OUT ON TUESDAY

Hi all... It was pretty simple to warped it...I can upload filebut only in RAR file=1,09MB2006-02-16_120651_warped-bonnet.prt.rar . I created itin Warp feature with Bend Tool. (rotation at 170 degrees)


And this is the rendered model of bonnet..View attachment 1836

Hi all... It was pretty simple to warped it...

Looks good but this method doesn't close the plug because the radius required for the bend is too big. I think there needs to be more documentation on Warps. Does anybody have any tutorials or links?

Huug, That's great that you found this solution. Is the Spinal Bend parametric?

 

[Miko]

Is the SPINAL BEND a deformation function ? Or it is only special sweep ? I cant find some informations about this special function ... Does anybody know where can I found some info.?

 

[Israr]

rcamp,


yes Spinal Bend is parametric.



Miko,


Download a file from the Files section of this forum that has been modeled using Spinal Bend. Redefine it and learn how it was developed.

Or takea look at my part! Resume the last two features, a solid and the spinal bend,and look how it's built.

Aspinal bend requires a(parametric, in my case sketched)curve that isjust as long asyour part, and is straight there were the product should not deform. It is a nice old functionality, with menu's at the right. It is not rewritten to the wildfire "dashboard" and ptc probably won't do that in the future.


Thanks for all your interest, and Miko for the documentation. I'll spent some time on it.

Huug:


My pleasure. I think, that tutorial of Warping isvery useful. I wasnever try this function in PROE before, but look like very powerful and iteresting feature.


But when I take a look atyour solution I must say:I mean that your uploaded file ofbonnet was pretty complicated to create and tedious. Why did you create firs surfaced model andthan solidifi it? Why you didtuse solid and warp? The topic was:"Who das succesfully used the Warp feature" And your solution is "Spinal Bend" hmm. I used less features to create itthan you because I used Warp.


(sorry for mistakes in sentences but if you can pleaserepair it and I will be very thankful)

I am still learning English language.

I think, it's interesting within discussion:

One thing annoying about the warp features is that flat surfaces (that remain flat) are no longer seen as planes. So you can't skethc on them without creating a new datum plane through 3 points at the edges.

The topic was:"Who has succesfully used the Warp feature" And your solution is "Spinal Bend" hmm. I used less features to create itthan you because I used Warp.

Surface modelingflowsthrough my veins. I hardly use ever solids. The reason for this isthat Ialways have to deal with complexmodels. Mostly plastic injection moulded parts, that come with drafts, rounds, parting lines, cutoff planes and all the geometry that is needed to get a correct cavity and mouldable parts, allthough I do not make use of mould design.When a models starts easy, it turns in most cases to a complex part, were several draft angles meet and rounds are desired. When it is build in solids, it can be awfully difficult to get it right.


But when a real simple part has to be created, like this bonnet,I simply forget to use solids. So it can look complex to newbies, but it's just the wayI work. Note the difference in file size when saving with the solid suppressed or resumed.


Butback to the topic: For presentation purposes I wanted the part to be closed, where the strap should look deformed in a natural way. The strap will normaly bend in three steps. I was thinking of the new warp feature to do this, but I didn't succeed in that. I turned out that Spinal Bend was the correct way to get the desired geometry, with thanks to mgnt8.


Conclusion: I still didn't succesfully used the warp feature!
