Complete mouse model - Shell / Thickness problem and convert issues

[Anonymous]

Dear all,

I know there might be similar thread to this one, but I am really suffering and the reason to that is not having enough knowledge to understand different environments and bodies in Fusion 360.

I don't know where to start, I cannot convert the model to be selectable to add thickness or shell, and even if I do there is a lot of intersections which cannot be fixed, I tried a lot and gave up now, the best I can do is provide you the screenshots as well as the file to kindly take a look.

Also if you disable the history you can see my main model which is done in sculpt mode, I've tried to go backward to that and find a way, but intersections make things impossible, I'm totally lost and don't know how to go to final step to print this out.

Thanks a lot for your time, the F3D file attached within this thread as well.

I'm a newbie has well, I'm sure someone will correct me if I'm wrong 🙂

But from what I can see, is the surface has to many "angles" , "sharp corners " , "Bevels"  for the Thickness or Shell Tool to deal  with, Try making a more smooth flowing model, shell it or thicken , then add bevels, fillets , opening for buttons last   .

Adding opening , fillets , bevels last, make it easier to make changes to them, with out having to go back to the start.

Also if you actually want to manufacture it, you need to think about what process your going to use to make it and design to match the process.

Sometimes when I'm not overly concerned about having the exact same thickness across the whole shell, I will quickly design a smaller version of the body I want to shell and then use it to "cut" the main body.

had a quick play,

if I removed the button opening , I could thicken it 1mm, but it forms intersecting geometry .

the red lines show the problem areas.

I checked your file, and to be honest, I think you're beyond helping ...

you have many issues so I'll try to point you at some of them, but before that, you really need to watch some more tutorials before going further in F360, to understand the differences between environments,  patch, solid, etc.

The first issue is the bottom patch. If you checked the bottom of your model from an elevation (side) view, you'll notice that the edges are not on the same level, so you need to cut horizontally so that you get a fully flat bottom edge loop, then use the patch to close it

The second issue is the sculpt environment. The topography of the sculpted body isn't a clean one, and that produces problems down the road, even if it finished form (got out to the model environment), but still, your biggest mistake is that you're trying to create the details in the sculpt environment, where they should be created in the model environment

I hope this help you understand what you need to work on

Best of luck

Thanks to both of you,

Yes that red lines ate the problem areas, 

I did cut the base, it looks ok, but still having errors, so I am thinking to redo all I did, or maybe find a way to shell out and not in, and adding such details in model environment is kind of impossible I think, the only way is patch modelling a I guess. believing this model is rubbish is hard as I worked a lot on it, but because I come with a 3ds max background, I really need a lot of work to get into Fusion 360 nature, I'll play around a bit, if no chance then will remodel it, and still have no idea to do it in patch or model environment.

Will keep you guys updated.

Thanks a lot.

New and quick start, did it just now, looks like its easier! 

and need to find a way to extrude the projected lines.

Ok, I deleted the constraints and used them to split the face 😄 hope this thread help other people too.

I'd have to thoroughly agree with @SaeedHamza that the T-Spline model was beyond help.It would just have taken a little bit more work!

So here are a few tips for better T-SPline modeling.

1. Model mostly (70%+)  in box mode and make sure you have a nice edge flow and no overlapping geometry. In fact your model topology was not that bad at all as it was all quad faces and if you make things look neat in box mode, the result will be a smooth surface with a minimum amount of NURBS patches.

2. Only add detail such as creases and additional edge loops when you are happy with the overall shape and proportions. It is much easier to handle a lower number of polygons.

3. Avoid creasing altogether and add edge loops. The result will be very smooth G2 fillets. No extra filleting needed. If you adhere to the first two tips this will be easy.

hmmm not so happy with this.. faced another problem, so whats the basics to cut them down? is there a way or I should start a new model again? I used the tutorial on Autodesk website, project curve and then split face, and now : 

Thanks:

And even at this stage Shell is not working too, so what do you suggest? when is the best time to add shell? and when is the right time to cut those buttons down? 

[Anonymous]

Removed the sections and shell worked, now I'm trying to add those buttons, have no idea if they will extrude in and keep the shell or not, but really gonna finish it today with your help 🙂

[TrippyLighting]

Actually I should have re-read my post. I would have to DISAGREE with @SaeedHamza on the T-Spine

[SaeedHamza]

lol, don't worry, the like was for the tips and NOT the agreement

Thanks to all, just decided to finish it asap due to having no time 🙂

So here we go. Any questions, send me a message or reply here 😄
