Modeling a wind-up clock

STEP 4

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 Line or Polyline command, create two lines:

Move 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 Circle 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 Loft command, connect three circles, and use Straight sections option:

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

With ExtractIsoCurve 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 Pipe command we will create a ring surface. Use 0.05 as pipe radius. Then, using BooleanDifference, just make a hole:

Mirror the leg, and the legs are done!
