Join Scott Onstott for an in-depth discussion in this video Continuing with Sweep and Sculpt, part of AutoCAD: 3D Surface Model Design.
- We're going to continue building spokes.…This time, we have to create the spokes…that go through these holes…on the upper flange of the transmission.…I'll pick a spoke, and select it,…and type, l + a + y + c + enter,…to change it to the current layer.…I'm going to orbit underneath,…so I can see the holes from below.…I'll select my chosen spoke line,…and move it up,…so that it snaps to the center of this hole.…Now, I'm going to draw a line,…up through the hole ...…
4 units long.…That should be enough…to penetrate through the flange,…and poke out on the other side.…Now, I remember, from before,…that this hole is 2.9, in diameter.…I'm going to design the spoke…to be just slightly smaller,…at a diameter of 2.8,…or a radius of 1.4.…I'm going to copy this line down,…the distance equal to the radius,…which is 1.4.…In doing so, I'm creating a path…that is the centerline of the spoke.…
Now, let's take a look, over here,…where the spoke meets the rim.…I just copied this lower line down.…That's the centerline of the spoke.…However, this centerline needs to go through…
