Using copy, rotate with reference, arraypolar, move commands I got the complete chain. I duplicated it with copy command and I had my first link. Later, I joined the mirrored curves, and built a surface from it, which I then extruded. Basically, I repeated the process I used when drawing the Disk Brake Rotor but with a different shape.įor the chain, I first drew one module with control points curve, mirroring curves to get it symmetrical. I used the command extrude to achieve the width. Regarding the chainring, I first drew the contour and the whole in it with control point curves, then generated the surface selecting the contour and trimmed the whole out. Later on, I used the pipe command to accomplish the shape.įor the grips, I drew the section first with polyline command and then used revolve through the handlebar axis to get shape. Using the control point curve command I drew the first half of the handlebar’s axis and then mirrored it to achieve symmetry. For the Hub I drew a line, half a curve which I then mirrored to achieve symmetry and then used the revolve command to get the surface.įor the Disk Brake Rotor I first drew the contour and the whole in it with control point curves, then generated the surface selecting the contour and trimmed the whole out. Having drawn the wheels I started adding some details. I then used the command revolve over an axis. To follow with, I drew the wheels with circle and pipe commands.įor the Rim I had to draw the section with control point curve command, taking into account its particular shape and details. I then used the command pipe to generate the tubes: Top tube, seat tube, head tube and down tube, giving the correct diameter in each case. First, i drew lines, with the lengths and angles I had measured from my 123D Catch model. Every single component is attached to it so I decided it was a good starting point. The first component I drew was the frame. I Used the model as a reference to measure every component of the bicycle, and then started my drawing from scratch. Using 123d catch software, and with the given pictures, I produced a 3D model of the bicycle. These pictures covered entirely the object, from a 360 degree visual. To start with, I took pictures to the selected object, using a DSLR camera and a tripod.
