    Drawing 3D Motorbike

    Registered forum members do not see this ad.

    So, I'm doing a CAD assignment and we've been asked to "Produce a 3D solid model of a mechanical vehicle assembly". So basically, make a 3D model of a car, motorbike, boat, etc. I've chosen to do a motorbike (see the attachment). As you can see, it's mostly finished, but I'm really struggling with the wheels. So if anyone could help with that, that would be great. Also, part of the question says to "Use materials to create a photo-realistic finish to your 3D model". What does that mean, and how do I do it?

    Thanks.

    Re: materials.

    That refers to a finish of some type (ex. - glossy paint). Materials can be applied directly to objects or assigned to layers. After the materials are applied you would need to place some lights and create a rendering.

    Re: your drawing.

    Ah......why did you create the motorbike using extruded surfaces? Why didn't you use solids as per the instructions?

    When is this assignment due?

    OK, thanks. So, do you have any advice for the wheels?

    I wouldn't worry about the wheels. You don't really have a 3D solid model in my opinion.

    A 3D solid model of a bicycle. The left side utilizes a 2Dwireframe visual style. The right side uses the Realistic visual side. No materials have been applied at this point.

    Note: I did not create this 3D bicycle. It is used here for demonstration purposes only.

    So if I wasn't supposed to extrude the 2D drawing, how do I do it?

    3D models can be created from 2D linework HOWEVER depending on the geometry and the method used you'll end up with either a surface or a solid. Unfortunately for you everything appears to be an extruded surface.

    An example of a simple rendering. The materials were brass for the padlock body and polished chrome for the locking portion.

    Disclaimer: I don't work at a job where applying materials, setting up lights, then producing a rendering of a 3D model is required. This is one of only three attempts I ever made so take it with a grain of salt.

    What about it? At least it appears solids were used. That's a start anyway. What other solid modeling or editing commands have you used thus far?
