Ie you used the Net Surface tool, then split holes for the wheels? At least it looks like that.
I would be interested in tools that you use for building of surfaces. For example:

I would be interested in tools that you use for building of surfaces. For example:


for the side of the car, I have used simple splines to construct the boundaries and inner control splines. The upper boundary (above the wheels and under the side window) is a Joined Curve made from 5 splines.

Yes, the side surface is a Net Surface with the wheel openings cut from projected curves. I have been trying to upload videos from my CamStudio software but the file sizes are too large. I need to purchase new, up to date video software.

Progress. A lot of spline and surface work. It's really difficult to document the fine details. I will try...

This topic pushed me to try to model a car. In this case AC Cobra 289.

Cars modeling is not my theme. But it is a classic of 3D modeling and excellent basis for other products.

I watched dozens of videos about car modeling in various CAD applications(basically Rhino and Solidworks). Unfortunately, most of what I saw, I could not use with a Shark.

Never modeling was a torture for me. After several hours I abandoned this idea.

I did not like:

1. Absence of the symmetry function
2. Very limited possibilities for editing the surface by points.
3. The results of applying Loft and Cover surfaces are often not predictable. I had a feeling that Shark models on its own without me.

Eh....? Hello! I'm here! I decide what to do and how it should look. :)

Sorry. My impression was that 300$ MOI looks more advanced(surfacing) in comparison with the expensive Shark.

4. An hour later the program crashed. After this crash all the reference images disappeared.

Oh oh!

So I decided to act in a more flexible way. MESH..... The Shark has very limited mesh tools. I used another software for mesh modeling. It is not comfortable. But in 30-40 minutes the main body was ready. Not super precise. But pretty accurate low-poly model.

I did not like:

1. Shark still badly imports OBJ files. I already reported it in support.
2. Shark partially changes the imported mesh. Not good!

But

I LIKE Shark’s SubD to NURBS tool. Make Associative is very very cool feature.

It was perhaps the only positive moment in my experiment.

Ah yes! Here are the results. It was an exercise. Therefore, only with superficial detailing.

Wow, that's really looking awesome :D
I think i have to start using this surface modeling too !

Very impressive (visual) model

However, can a poly model ever be part of a (physical) design process ?

Jol,

For relatively simple projects, I am sure it would be fine. But...

I recently spoke to a friend who works in the GM Design Studio and at this point in time, they (and I assume all vehicle companies) do not use Sub-D at all for anything official. They may whip up a concept with it. However, most Industrial Designers working in that environment are 3D sketching on tablets and then transfer that work to the actual surfacing crew for the "real" deal.

You're right. I'm a visualizer. Therefore, this model is based entirely on the reference images. To build real car based on this model is not possible.:)

Originally it was a surface project. I tried to model this entirely using standard Sharks surface tools. I like CAD modeling for its accuracy. But I did not succeed. I did not find a way to seamlessly "sew" this a smooth streamlined shape.

For my work a fast result is very important. Therefore, I use various ways of modeling. It was an attempt to see if I can use Shark for this type of objects.

This is not a critique of PunchCAD. ViaCAD was my first CAD software. I do not have time to learn another soft. So I want to get the most out of it.

@NeuTechFLA was the first who showed Shark in a serious project. Prior to that, I have not seen anything like it. It was a serious impulse for me.

I'm not competent in engineering. Yes, SubD modeling has no high precision. But I think that many organic- and free-form objects can be modeled polygonally. In combination with NURBS, it works great in many industrial areas. Product/packaging modeling etc... Why not? 3D Printing, Sketching, Concept Design, Prototyping are in any case.

Same - I know of people spending months working on just one part of a car as it adjusts to reflect styling requirements, functional constraints, engineering parameters, manufacturing limitations - sometimes over and over again. I can't really see poly modelling being a useful part of that. ... Would be great if it could though !!

I can certainly see poly modelling has a place in design exploration, as suggested - and I hope that the team continues to improve our Sub-D tools until they're fully functional and joyful to use !

(As for mirroring - there are tools here for auto mirroring - but I do agree, it would be useful to be able to set a 'universal-mirror' (along Y=0 for example) in order to automajically instance everything on the offside of a car or product. I would use this daily).

Hello digitalphaser,

I am very, very happy that you have tried to model and demonstrate Shark's surface tools.

It's been a long time since I gave up modeling in surface mode with Shark.

He misses a lot of things and his engine is old.
I hope Tim and co will have read your post and finally realized the limits of this mode.

The absence of preview mode in surface modeling and the poor option for the connections of tangeance.
Low option for editing surfaces in point mode.

I love SharkFX for its volume modeling and its ergonomics and flexibility.

By cons, I hate his MTS (technical 2d drawing) mode that is horribly buggy.
The realization of technical plans 2d is a hell in terms of time and is absolutely not usable in professional mode.

It's time for Punch! is concerned about the recurring demands of its users to optimize the core of this software, which deserves better than that.

This looks like a play game. How to setup a new rotating view midpoint while drawing a line? Do you know about all the special zoom, rotating, pan view-commands in shark? No other CAD-Program have this, and this make the visual work very much more effective. I guess a compare with shark is not possible. We say in germany Klickibunti. A button for rotating the view is senseless and you cant change the view while working with a tool. And you have to take a tool after each operation. Please don't tell me from such a arcade game.

MPSchmied, I do not understand this. Is your post meant for this thread or an different thread?

We say in Germany:"Every sandpiper praises its swamp." ;) It is also possible that our goals are somewhat different.
