Toy Car body remodeling

[ninolemann]

Hello,

I'm Trying to remodel a cartoon car so that i can use its bodywork for a slotcar game.

i am failing miserably.

- shelling doesnt work. too detailed.

- i can delete faces, (like the wheels, the bottom, the seat) and thicken everything that i want. this only works up to 0.9mm, but at least a solid car body remains.

the chassis with all the electronics has a lot of overhang behind the rear axle, so i wanted to reshape the tail like a thirties streamline boattail car. no chance....

(of course, the model from grabcad needs to be resized for the tiny car chassis)

is there anybody with a lot of sculpting experience who could assist me in:

widening th body stance for the rear axle

remodeling the tail so that the overhang is covered nicely?

shutting the whole surface thing to end up again with a complete  solid body?

Thanks.

attached are the cartoon car STEP and the Chassis STEP.

Any help is appreciated.

No step file to be found.

But, yes, I can help with sculpting. It will be a new model though.

Depending on the model, converting a STEP model (B=Rep) into a T-Spline often does not yield usable results.

But where there's a will, there's a way 😉

This Tutorial is quite old now and doesn't use Sculpt environment - but it might get you started

Thanks for the assistance!

To explain a bit further: a friend of mine is making a parcour for kids, to learn about exoskeletons, prostethics and even BCI controls (Brain-Computer-Interface). Part of it is surpassing a computer driven slotcar with another car in a race, controlled with the output of brain activity (there are easy sci-fi-like headsets available, who measure your general brain activity as a control value).

The toy cars look really futuristic, and for the parcour they want something different.

I had something like donald duck's 313 in mind, and i found a shape on grabcad. but the chassis i modeled will not fit at all, so i probably do it all by myself.

this time, i'll try to attach the STEPS.

should i try with the canvas trick? or whats the best way to capture a form?

I am not sure what you are referring to with "the canvas trick" but I doubt it's needed.

This vehicle was created from very simple geometric shapes and can be re-created entirely with the solid modeling tools in Fusion 360. No sculpting needed. It's not that it could not be used, but it isn't needed 😉

We'd need to have a better understanding of what exactly you want to change e.g. a pencil sketch with dimensions etc to be able to provide some guidance as to how thatch be done.

That is what I would do.

If you can find some good straight-on images from top, front, side... ...you can put those on canvases to trace over.

Better yet, if you can shell out $25 and use photos and caliper measurements of actual toy.

Donate the toy or keep it for yourself when done.

If only images were available that would certainly my preferred method. It's worked fine so far.

However one of the posts had the actual model attached. Below is an image.

I that case I'd recreate that model with parametric solids, an take measurements with the digital tools in Fusion 360.

If I were to convert this into a sculpt model I'd export a .stl, open it in Blender an re-topologize the geometry either manually, or using Retopoflow. Then I'd export the resultant quad mesh into Fusion 360.

Soo,

I made a small car body that'll do.

This is a side project, so i couldnt do it any faster.

In the end, it looks like a Lotus Seven, but the guy i made it for likes it, so its good enough for me. It even has a small PMMA windscreen...! (see attached picture)

Turns out you can do a lot in FUSION, if you are just skilled enough. Or determined...:)

(it was the latter for me...)

Thanks again for all the help and support! I guess this Thread can be considered 'closed'..

Kind regards,
