Hi All
I am currently converting, Catia Models to Inventor models. Iam facing serious problems in matching the profiles expecially in loft areas. Attached is the file where there was a mismatch with loft features. Some body can help me in solving the problem.

I'm not sure i can help you, but i did notice that the translation report said there was an error:
Severity Entity Id Message
Warning 51 Some Surfaces have been truncated
So are you sure your imported model is correct?

To make sure, myself i improted once again , but it was still having the same translated report. And when i overlap Catia file and converted file in Catia V5 they both are matching.
So, importing is not a problem.

ya, i tried to do in that way also, i created new sketches in inventor but there are not really useful to match the profile. I think in Catia there was an option where we can select the section parallel to a plane, but i think in inventor we are not able to do it so (Even that option is not highligthing in conditions Tab).
attached is snap shot of catia Loft

Why do you need it as a native Inventor feature? Is it not correct from Catia?
Can't you simple convert to a solid in Inventor or do you need to edit the Loft?

Hi! The two products are using two different ways to compute loft surfaces. One can argue that if you bring the same sections from Inventor to Catia, the loft would look different there too. It depends on how one CAD software maps the sections and define the smooth surface across the sections. There are assumptions made by each software to make the loft work The assumptions may not be the same.
Thanks!
Hi John
You are correct, but we have to admit that some thing which was already in production cannot be changed now, Those parts are made with catia and now they want to change something in model and that cannot be done in inventor.
The one thing which i dont understand is, why cannot we loft a sketch parallel to a plane , in the same way how we are doing for sweep. If we can do it, i think we can solve this problem to maximum extent.
The main problem is, in conditions parallel to plane option is not at all being highligted for this part...

Hi! I must have misunderstood the issue then. I am not sure what you meant by parallel sketches cannot be lofted. I thought the sketches are all paralleled and they can be lofted but the shape looks different from its original design. Is it true?
Thanks!
To Give more clarity on my thinking why they are not matching, i made a presentation and same is attached to this.
Hope some body will help me
Can you post image of the actual part?
I don't mean to "muddy the water", but the Catia part doesn't look like "good geometry" that I would be trying to match.

Actual part is a core and yes i have checked actual part and catia model are matching with each other. It is because the fact that this is the model which was used for making Patterns at foundry.
Ahh, now that I know the part shown is a core it makes more sense.
If I get time I will try to see what I can do to accurately reproduce the geometry.
I didn't think the tangency looked right in this area, but know what is there

Hi! I think you might be looking for "Area Loft" (3rd type of Loft). You will need a centerline rail going across sections. You can specify the section area at any given point on the rail. Could you take a look?
Thanks!

It will be great if you can help me in finding a possible solution for this problem, because there are lot of models in the same way.
Hi John
Yes i tried to change the are in area loft . But it was not yielding any result for my problem.
