Modeling a wind-up clock


In this step we will create two legs for the clock. For that we need to set two lines which we will use as reference. I have aproximated the angle between the two legs to 60 degrees.

Using or command, create two lines:


the two lines in approximately the middle of this surface, and use Intersection command to get the intersection points like on the image below:


Using Copy command, copy the points two times, first with 4.0 as distance on the lines, and the second time 2.2.


Next, using command, create three circles, with 0.1, 0.5 and 0.7 as radii. Then, using OrientOnCurve command, orient them on line using points as reference places where to place them. Use cop option in OrientOnCurve to copy the circles:


Using command, connect three circles, and use Straight sections option:


Using command, extrude the biggest (0.7 in radius) circle and input the -0.1 as distance value:


With extract a V direction curve, in this case it will be a circle:


Next, we need to make a surface out of this circle. Using command we will create a ring surface. Use 0.05 as pipe radius. Then, using , just make a hole:


the leg, and the legs are done!

    Hi, nice tutorial!

    But is the video already on? I’d like to see how to render it with V-Ray! Thnx! keep up the good work!

    I`m sorry but I don`t understand the steps in the picture N=5, the step with the controllpoints
    when I move them there are no changes and I see in the picture the backmost part of the clock is thinnier
