HI Steve,

Great model.

The only thing that i find little weird is the break pad, seem to be very, very close to the interior of the rim.

Unless it is optical illusion.

Hi Denis,

It is very close... but I made sure it missed the rim :) I rebuilt it twice so I could get the angles correct. In the end to ensure I had the biggest disc size possible, I drew 2 curves (the top half) inside the rim (using the rim and hub as guides, then mirrored, joined, planar and extended the caliper to give depth.

Thanks very much everyone for your feedback..

Steve

Nice model and render Steve. I'm guessing you've got a fair bit of experience with another modeller!

Looking forward to seeing more of your work.

Hi Mark,

Thanks very much. Yes, you're right. I have owned Modo since 201, but subdiv modeling seems to be my nemesis. I am alright with small modeling tasks in Modo, but when it comes to big stuff like cars they end up looking like my patio.. all lumpy :( I wanted a modeler that could let me be creative and didn't get in the way.. and Moi has certainly done that. :)

I have just finished the hub bolts, valve and pad plate. I'll upload when it has rendered.. might try a different colour scheme too.

I am seeking some advice for my tyre ;)

1. Can I align text to a curve? I tried yesterday without much success. It is for the side wall of the tyre. I managed to get the Y of yokohama aligned but it was a bit hit and miss using rotate and the bottom to points of the Y to align to a circular curve the same diameter as the centre of the tyre. Is there an easy and accurate way to do this?

2. Also the tread of the tyre. My thoughts are to create a boolean array of blocks or tubes depending upon the style of tread and then diff the array from the tyre. Are there any other ways of doing this?

Thanks again all.

Steve

Hi Steve,

> 1. Can I align text to a curve?

MoI doesn't currently have a function for that, but it is definitely something I want to add in the future.

Currently the easiest way to get text along a curve is to do it in a 2D illustration program and import it into MoI. There is one 2D illustration program called Expression which is available for free from here:

One other technique is if you project some curves on to your object you can then do something like a sweep along them to make a tubular cutting object to use for the boolean difference.

Check out here for an example:

Michael... you are a star! Thanks.

I have inkscape... would that be suitable for the text?

I like the idea of projecting the curves onto the surface too.

Thanks

Steve

Hi Steve,

I may be misunderstanding what you want to do but projection sound like the way to go. I used that to do a ship's nameplate, projected onto the ship's hull. It works nicely.

Actually, re-reading your post, I reckon I did misunderstand what you want to do. Is your concern that you want to have the letters projected on the sidewall radially from the centre of the hub?

Perhaps you can do something like the following images? Work out the start and end positions for your complete text, do a circular array of the line markers, then on the vertical add each letter, rotate the letter from the hub centre into position using the line markers as your guide and repeat for each letter in the text. Finally, you can project the curves onto the sidewall of the tyre.

Alternatively, you could rotate the tyre, project, repeat.

Hi Mark,

That's an excellent method! I will give that a try later. Thanks very much for all of your help.

Hi Steve,

> I have inkscape... would that be suitable for the text?

Yes, I think that would work as well, the only thing is that I don't think that Inkscape exports to the older style AI format, but you could try exporting to PDF format. PDF though is a complex file format and MoI's PDF importer is not always able to make sense of them.

That other program that I linked to before Expression does export to the more simple AI v8 format, and that format is much more reliable for getting 2D data over into MoI though.

Very cool render and sculpt!

Thanks Michael.

In the end I used a combination of sketch (for mac) which exported as eps. Then used Marks advice using lines from centre and rotating each vector text character around the tyre. The only problem was getting the spacing correct as the text is proportional. Oh.. and it took ages! lol.

Thanks again

Steve

Thanks very much Pilou. :)

Well, I'm going to call it wraps on this model. Added wheel nuts, adjusted the rake of the spokes, added valve and cap and built the tyre. The tyre was... erm... an experience to say the least, but I got there in the end.

Thanks for your help folks...

Cheers

Steve

Beautiful! Love the renders. Can't wait to see more !

Very nice model and rendering keep it going!

Very nice. MoI is winning me over as my choice as a vehicle modelling program.

Out of curiosity, what was your rendering process? My current plan is to take my exported models into Blender and use Luxrender, but I'd love to know how you're doing it.

Hi Aaron,

Thanks very much.

I am using Simlab (Rendering Edition). I used to use Hypershot Web edition but their recent upgrade and dropping the web edition means a very expensive upgrade.. Simlab uses the same engine as Hypershot.

I export as an obj with pretty high resolution (but not max). Import into Simlab, assign materials, set up the environment and lighting and render. I prefer Simlab over Octane because the macbook pro has a 330M GPU which is not the fastest. Simlab uses CPU and as I have 4 cores it renders pretty fast.

I believe other Moi users do use your method with great success, so you should be fine with Blender and Luxrender, if that is your preferred tool chain :)

Cheers

Steve

Thank you for the advice - I'm always looking for cool ways to render things.
