Hybrid Design?

[jackk]

I just saw another post that dealt with Hybrid Design in R14.

Now that its been out there for awhile, I'd like to ask the same question that was asked earlier: Why Hybrid Design?

Is anyone using it? What are the advantages?

See my response on Volumes. A certain large manufacturer recently dumped their in-house written CAD system in favor of V5, but they wanted certain functions added to it.

Hybrid design is when a combination of open part modeling,
solids and possibly freestyle surfaces are being
developed at the same time in the same part or product.

it needs a license to use it.
Example: my company only has GSD but not the freestyle surfaces, it requires another license to use freestyle surfacing.

check the catia domain in the link below.

I don't get it guys... Hybrid design, freestyle surfaces, requires a license...

HD2 *IS* the license for hybrid design. It contains GSD, in place of GS1. (basically GS1 has no LAW funcitionality, whereas GSD does - $8000 difference)

Additionally, the "hybrid" part comes from the ability to use surfaces and solids in a "hybrid" fashion. There is ABSOLUTELY NO FREESTYLE functions in "hybrid" design - at least not the base HD2. FS* (freestyle) pacakages are add-ons.

This is the "advanced" surfacing package. Nothing magical about it.

I don't think this thread is regarding licensing.
I believe the question was "Why Hybrid Design?"
If I understand jjack's question, he wants to know why someone would want to create wireframe elements and surface features within the same body as your solid features.
How is this better than having these objects in an openbody?

 

[solid7]

If that's truly what his question was in reference to, then I'll simplify my previous answer:

You CANNOT create complex surfaces without either hybrid design, or some other package + GSD. (Hybrid design = HD2 = MD2+GSD)

You can choose to use, or not to use the hybrid design functionality, but the package, on the whole, makes the most sense of all, if you intend to do surfacing. (other than freestyle)

It's the basic equivalent of the "advanced design and detailing" package in V4.

It works extremely well if you are using V4 data, or if you are using B-REP data from other packages. (if you don't care about feature based data)

Hope that helps.

I find it easier to work in the old fashioned way, with the wireframe and surfaces in openbodies, and when going solid to work inside the part body.

With hybrid design your work is more structured in a "cronological way" (more like pro/e) but I still dont get used to it

 

[solid7]

I would also compare the "hybrid design" mode to working in SolidWorks, perhaps just a little...

Yes - my original question was to find out the advantages and disadvantages of using the new Hybrid Design feature that was added in R14. (I'm sure other people are interested in the licensing aspects - but I'm not).

When my company migrated to R14, we made the recommendation to our users that they not use this new Hybrid Design feature, because we felt it would cause too much confusion. As Lordraille explained it above - ordered geometric sets are difficult to work with!

It's been awhile, and I was wondering if anyone has come up with any advantages to using Hybrid Design. So far, I think I only have 3 items on my list:

ADVANTAGES OF HYBRID DESIGN:

1. all geometry can be in the same set, so you don't have to look far to find the surface that trims the solid

2. it's similar to SolidWorks (thank you Solid7)

3. you can transfer all the geometry in the part body, not just the solid geometry. (but I forgot what we were transferring to - was it V4 ?)

DISADVANTAGES OF HYBRID DESIGN:

1. It's different from the normal mode, so it's confusing to the average user

2. Wireframe and surface geometry must be in order (either cronological or hierarchial - pick one)

Any more?

thanks everyone, Jack

PS: you can call me JJack or Jakk or even JAK, but please don't call me late for dinner

Probably there is no universal answer like: hybrid design is Good or Bad.

I think there are two main scenarios:
1. If you need some rather simple surfaces, wireframes or planes for your solid designed part it is more useful to place these entities inside PartBody. This makes your design more structured and clear for others.
2. If you need complex surfaces with a long design history it is definitely better to make it inside OpenBody. The OpenBody gives you more freedom what is essential for complex surfaces.

I completely agree woth JOGLA

when working with complex surfaces, and large amounts of them is far easier to work with openbodies.
