Surface design tools for the future??

Hi all,

Just wondering if Autodesk is planning to a surface modeling module for IV.
I am not talking about the so-called surface modeling in IV 5.3 and 6, but
real surface modeling - something you can actually create an idw from. The
most anoying thing is that iges files (I am talking big files of car body
panels) just dont come through on the idw!!! What is the point? How do I
show my imported iges components?

I am sure SW can do this???

Thanks for the most userfreindly package ever anyway!!!

Dear Pieter

I am trying to loft a body of a sports car at the moment.
irrelevent but I may have some thoughts that help.
The IDW is a 2d enviroment I suspect you need to pull the iges surfaces into either a part file or an assembly. (Inventor should sort this) I suspect It will be easier if you can do each panel on its own.
Once the surfaces are in the part If I remember right from a dealer demo you need to promote them to make a solid panel
then you can make an idw file with a nice shaded views of the panel and add the key dimensions.

sorry you don't like inventor, I am rather fond of it. Stick with it the rather sparse interface is great when you are doing jobs you know how to do.
We all know that the best system is the one you know how to drive.

I have had some success with IGES from 2d Bentlty to Autocad then to Inventor. Went via Autocad because I am more familiar with it and it's a general system rather than the specialised modelling system that IV is

hope this helps Jon G

Jong, what I think Pieter was saying was:-

You can't create drawing views of either

1) Imported surfaces (Unless you thicken or stitch into a solid but you
might not have much chance with complex parts)
This applies whether they're promoted or not.

2) Solids which have had faces deleted and are now surface models. (Unless
you thicken or heal and solidify them)

This really needs to be added, as it's something MDT has done for years.
Also, why aren't surfaces in ipt files saved if they're not promoted? If I
spend 2 hours importing an IGES file, I want to save it before I do anything
else, but if it isn't promoted, you end up with an empty file!

This workflow of importing surfaces and having to promote to be able to save
them is in my opinion very wrong - When you save a file, it should look just
like it did when you saved it when you re-open it. I can't think of any
other system that has "construction geometry" which gets discarded on
saving.

I know the quick answer is "promote them" but it can take a long time on
complex surface models, and it's easy for users to forget to do this. Auto
stitch and promote helps, but it increases the time taken to open the file
by a large amount.

Whilst I'm on the subject of surfaces, I'd also like to see :-

1) Quicker importing of IGES files. MDT is still a lot quicker to import the
same IGES (or STEP for that matter) file as Inventor.

2) Be able to colour surfaces - Having them all yellow is difficult to work
with on a complex model.


(complaining mode off) - Inventor 6 is a definite step in the right
direction to having integrated solids and surface editing, but a bit of fine
tuning wouldn't go amiss.

Cheers

Rory

Yea... thats excactly what I think!

Autodesk definitely has the best platform when it comes to ease of use. But
we want the power functions now - more surface tools (not construction
surfaces) and lofting, shelling and filleting of that can be improved!

I am not complaining guys... just asking for more! Thats what a paying
customer has to do???

Regards,
Pieter
